Tag: component of the cell

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.
