Cytoplasm - class-IX

The nucleus contains the genetic material of the cell and thus regulates all the activities of the cell.

Cytoplasm is a semi-fluid jelly like substance which contains various organelles and inclusions. It also contains a number of inorganic substances forming a clear true solution as well as organic substances like lipids, proteins and carbohydrates. It is homogenous and colourless in nature.

The peripheral zone of cytoplasm is a thick and jelly-like substance known as plasmogel. The neighbouring area of the nuclear region is thin and watery and is called as the plasmosol. It helps to regulate the amount of water needed by the cell in the cytoplasm.

Let's say, that we took a plant cell and used specific digestive enzymes to digest it's cell wall. 

The main arena of various types of cellular activities is the cytoplasm. Cytoplasm represents a bulk of protoplasm excluding nucleus and vacuoles. The inner part of cytoplasm is called as endoplasm and it is usually in perpetual motion called cyclosis or cytoplasmic streaming. Cytoplasm has various types of cell organelles. Cell organelles are highly organized subcellular protoplasmic structures that have a distinctive shape, chemical composition and function.

Cytoplasm can be defined as a thick solution that fills each cell and is enclosed by the cell membrane. It is mainly composed of water, salts and proteins. In eukaryotic cells, the cytoplasm includes all of the material inside the cell and outside of the nucleus. The cytoplasm is about 80% water and it is usually colourless.

Nucleoproteins are synthesized within the nucleoplasm, which is the fluid contained within the nucleus where DNA and RNA processing occurs.

The semicircular tube like structures present in the cytoplasm are Endoplasmic reticulum. 

The jelly like fluid that fills a cell is called cytoplasm. It is made up of mostly water and salt. Cytoplasm is present within the cell membrane of all cell types and contains all organelles and cell parts. It is made up of eighty percent water and is usually clear and colourless.

Basically cytoplasm is the substance that fills the cell.It is a jelly like substance and it is made up of eighty percent water and is usually clear and colourless.It is thought that the component molecules and structures of the cytoplasm behave at times like a disordered colloidal solution(sol) and at other times like an integrated network,forming a solid mass (gel).This theory thus proposes that the cytoplasm exists in distinct fluid and solid phases depending on the level of interaction between cytoplasmic components.Cytoplasm also constitutes numerous salts and is a very good conductor of electricity.

The cytoplasm comprises cytosol and the organelles. Organelles are usually membrane bound structures inside the cell that have specific functions. Some major organelles that are suspended in the cytosol are the mitochondria, the endoplasmic reticulum, golgi apparatus, vacuoles, lysosomes and in plant cells chloroplasts.

Kernplasm theory was proposed by O. Hertwig. According to the theory, during the life period of a cell, a constant ratio exist between cytoplasmic and nuclear masses and this maintains equilibrium between the cytoplasm and the nucleus.

Cytoplasm is a gel-like substance present in all cells. All of the cell organelles are suspended in the cytoplasm and perform life sustaining activities and thus cytoplasm is called as living fluid.

Cytoplasm is a thick solution that fills each cell. It is enclosed by the cell membrane. It is made up of water, salts and proteins. In eukaryotic cells, the cytoplasm includes all of the material inside the cell and outside of the nucleus. Hence, the correct answer is the option A.

Cytoplasm is a jelly liquid surrounded by cell membrane that consists of various cell organelles. It is the site of many biochemical reactions that are vital and crucial for maintaining life. However replication of DNA takes place in nucleus which is present in cytoplasm. Hence cytoplasm is not the site of DNA replication.

The cytosol is the portion of the cytoplasm and made up of cytoskeleton filaments, some dissolved molecules and water. The cytosol's filament is the protein filaments such as actin filaments and microtubules that make up the cytoskeleton, as well as soluble proteins and small structures such as ribosomes, proteasomes. Thus, the correct answer is option D.

• Cytoplasm is the jelly-like fluid surrounded by the cell membrane and holds all the organelles. 
• The cytoskeleton present in the cytoplasm gives the cell its shape. 
• The cytoplasm constitutes of dissolved nutrients and it aids to dissolve waste products.
  
  Hence, the correct option is C .

Cytoplasm is the jelly-like fluid present in cells that hold organelles and surrounded by the cell membrane. Besides giving shape to the cell, the cytoskeleton facilitates the movement of the cell and the different substances found within the cell. 

Cytoplasm is the jelly-like fluid surrounded by the cell membrane and holds all the organelles. It is the site of many biochemical reactions that are vital and crucial for maintaining life. The cytoplasm is the place where the cell expands and growth of the cell takes place. The cytoskeleton of the cytoplasm provides shape to the cell and it also facilitates movement.

Answer is option C i.e. "Permeability"
Cytoplasmic streaming is the flow of cytoplasmic components. It plays an important role in many cellular functions which are dependent on the permeability of the cytoplasm. For example, cell signalling through the cytoplasm. It helps in movement of larger molecules and subcellular structures through the cytoplasm.

Organelles are usually membrane-bound structures inside the cell that have specific functions. Some major organelles that are suspended in the cytosol are the mitochondria, the endoplasmic reticulum, the Golgi apparatus, vacuoles, lysosomes and in plant cells; chloroplasts. 

Cytoplasm is the jelly-like fluid present in cells that hold organelles and surrounded by the cell membrane. The cytoplasm has three major components- the cytosol, organelles and cytoplasmic inclusions, of which the cytosol is the thick fluid where other cytoplasmic elements remain suspended. The cytosol consists of 70% to 90% water, and it is usually colourless. 

The cytoplasm is the jelly-like matrix in the interior of the cell. The chloroplast contains the chlorophyll pigments which are involved in the production of the food. The solar energy is captured and used for making the food for the plant. The cytoplasm is the site where many cell processes takes place.

The nucleus is the site for DNA replication and transcription. Translation is the process of synthesis of polypeptides by polymerization of amino acids on ribosomes using the mRNA triplets as a template. Ribosomes serve as the site of translation and the process takes place in the cytosol. ER is eukaryotic organelle with a network of tubules, vesicles and cisternae within the cells. Ribosomes are present on the surface of RER but not on SER. Golgi complex serves to modify and pack the proteins synthesized on ER by ribosomes.  The correct answer is C.  

The terms cytoplasm and nucleoplasm were given by Strasburger in 1882. Cytoplasm is the bulk of protoplasm excluding nucleus and vacuoles. Cytoplasm is differentiated into a cytoplasmic matrix, cell organelles and cell inclusions. Nucleoplasm or nuclear sap or karyolymph or karyoplasma is a colloidal complex that fills the nucleus. Nucleoplasm contains the raw materials for the synthesis of DNA and RNA.

The nucleus is the main organelle which controls the activities of all the other organelles present in the eukaryotic cell. 

• The jelly-like semifluid complex of cytoplasm is called cytosol or cytoplasmic 

• In the eukaryotic cell, the cytosol is surrounded by the cell membrane and is part of the cytoplasm, which also comprises the mitochondria, plastids, and other organelles except nucleus. The cytosol is thus a liquid matrix around the organelles.
• So, the correct answer is 'Both B and C'.

Cnidocytes contain stinging structure known as nematocysts. Cnidocytes in tentacular region help in capturing the larger prey as their nematocytes discharge toxins into their prey.

Cytoplasm is the fluid which is present in the living cell. It lies between the cell membrane and the nuclear membrane. It consists of 80% water. It is a colorless liquid which holds the cell organelle and helps in intracellular and intercellular transport. The cellular process like glycolysis and the cell division occurs in the cytoplasm. So, the correct answer is option B.

• The gel part below the plasma membrane is ectoplasm.
  
• The cytoplasm of the cell can be divided into two i.e, ectoplasm and endoplasm.
• Ectoplasm or exoplasm is the outer, non-granulated gel-like part of the cytoplasm of the cell near to the plasma membrane.
• Whereas. the endoplasm is the inner granulated layer of the cytoplasm.
  
• So, the correct answer is 'Ectoplasm'.

• The main arena of various cellular activities of a cell occur is cytoplasm.
  
• Cytoplasm can be defined as a jellylike material present within the cell (inside the cell membrane) which surrounds the nucleus.
  
• All the cellular organelles such as mitochondria, the endoplasmic reticulum, and chloroplasts, are contained in the cytoplasm (all the cellular activities carried out here).
• So, the correct answer is 'Cytoplasm'.

Proteins required for nuclear function are synthesized in the cytoplasm by ribosomes and then transported into the nucleus through nuclear pores.

The streaming movement of cytoplasm around the central vacuole in plant cells is known as rotation or cyclosis.

The cytoplasm is a fluid found in cells and the organelles suspended within. Cytoplasm is found in eukaryotic and prokaryotic cells. The fluid of cytoplasm is called cytosol.

Cytoplasm is the jelly-like fluid present in cells that hold organelles and surrounded by the cell membrane. The processes of growth, expansion, as well as the division of the cell, take place in the cytoplasm. The nutrients are absorbed and stored in the cytoplasm so that these can be used by various organelles when needed. The cytoplasm also helps to dissolve the waste products. 

Ribosomes are cell organelles, which are present in free or in bound form. They are involved in the synthesis of proteins.  
The cell membrane is the outer covering of the cell, which protects the cell. It also supports the framework of the cell. 
The cell wall is a protective outer covering of the cell. It supports the contents of the cell and protects from pathogen attack and wear and tear. It is made of cellulose, lignin.

Movement of calcium ions in and out of the cytoplasm is thought to be a signalling activity for metabolic processes. In plants, movements of the cytoplasm around vacuoles are known as cytoplasmic streaming. 

Cytoplasm is the jelly-like fluid surrounded by the cell membrane and holds all the organelles. It is made up of eighty percent water and is usually clear and colourless. It helps in intracellular exchange of materials.

Cytoplasm is the jelly-like fluid present in cells that hold organelles and surrounded by the cell membrane. In eukaryotes, the nucleus of a cell is separated from the cytoplasm by a double membrane, known as a nuclear membrane. The cytoplasm of the animal cell is made of proteins, carbohydrates, salts, sugars, amino acids and nucleotides. 

• Cytoplasm refers to the living the material or the protoplast within a cell excluding the nucleus.
  
• Therefore, extracytoplasmic cell organelle refers to those organelles outside to the cell cytoplasm.
• A nucleus is the only cell organelle excluded from the cytoplasm.
• So, the correct answer is 'Nucleus'.

The cytosol is also called as cytoplasm in a cell which holds the organelles. It consists several enzymes for different activities such as glycolysis. Glycolysis is the breakdown of large molecule glucose to simple molecule pyruvate. uses its dissolved enzymes to break down all of those larger molecules. The products can then be used by the mitochondria for the formation of energy.

• Protoplast refers to an entire cell including the cell membrane, cell organelles and the nucleus, excluding the cell wall (in plants and few algae).
• Cytoplasm refers to the living the material or the protoplast within a cell excluding the nucleus.
• So the correct answer is 'Cytoplasm'.
