Questions Related to cytoplasm

Gel part below the plasma membrane is

  1. Ectoplasm

  2. Endoplasm

  3. Plasmalemma

  4. None of the above


Correct Option: A
Explanation:
  • 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 activities of a cell is

  1. Mitochondrion

  2. Cytoplasm

  3. Nucleus

  4. Plasma membrane


Correct Option: B
Explanation:
  • 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 functioning of nucleus are formed in

  1. Cytoplasm

  2. RER

  3. Nucleolus

  4. Mitochondria.


Correct Option: A

Which one is not properly paired?

  1. Golgi apparatus- Breaking of complex macromolecules

  2. Endoplasmic reticulum- Protein synthesis

  3. Mitochondria- Oxidative phosphorylation

  4. Chloroplasts- Photosynthesis


Correct Option: A
Explanation:
A. Golgi apparatus is an organelle found in the eukaryotic cells which forms a complex of vesicles and folded membranes within the cytoplasm that is involved in secretion and helps in intracellular transport.
B. The endoplasmic reticulum (smooth and rough) is an interconnected network of flattened, membrane-enclosed sacs which helps in the synthesis of lipids (SER) and proteins (RER).
C. The mitochondria is a double-membraned cell organelle (powerhouse of the cell) which is the site of the ETC and synthesis of ATP molecule or oxidative phosphorylation.
D. Chloroplast is a plastid which contains chlorophyll (green pigment) and is  present in the green parts of plants where photosynthesis takes place.
So, the correct answer is 'Golgi apparatus-Breaking of complex macromolecules'.

Most of the water found in the young cell occurs in

  1. Cell wall

  2. Nucleus

  3. Cytoplasm

  4. Vacuoles


Correct Option: C
Explanation:
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 colourless 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. 
The nucleus contains genetic material like DNA and RNA and helps in the inheritance of genetic characteristics.
The cell wall is made up of cellulose and provides structure and shape to the cell.
Vacuoles are the storage organelles which stores air, water, and food.
So, the correct answer is option C.

In rotation type of cyclosis, the cytoplasmic matrix flows in _____________.

  1. One direction

  2. Two opposite directions

  3. Different directions

  4. Side-ways


Correct Option: A
Explanation:
Answer is "One direction" i.e. option A
Cyclosis are movements of cytoplasm within a cell. Cylosis is said to be rotational when the protoplasm moves around a single central vacuoles in either clockwise or anticlockwise direction. Such movement of cytoplasm are observed in leaf cells of Hydrilla, Vallisneria.

Movement of cytoplasm around a vacuole is

  1. Circulation

  2. Rotation

  3. Regulation

  4. Somersault.


Correct Option: B

The fluid in which organelles of the cell are suspended is called ___________.

  1. Cytosol

  2. Chromoplasm

  3. Chromoplast

  4. None of the above


Correct Option: A
Explanation:

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

The process of growth and division takes place in the

  1. Nucleus

  2. Plasma

  3. Cytoplasm

  4. None of the above


Correct Option: C
Explanation:

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. 

Cytoplasmic inheritance is due to

  1. Plastids

  2. Mitochondria

  3. Cytoplasmic particles

  4. All of the above


Correct Option: D
Explanation:
Extranuclear inheritance or cytoplasmic inheritance is the transmission of genes that occur outside the nucleus. It is found in most eukaryotes and is commonly known to occur in cytoplasmic organelles such as mitochondria and chloroplasts. Mitochondria with their mitochondrial DNA from the mother's egg cell are incorporated into the zygote and passed to daughter cells,

So, the correct answer is 'All the above'.
