Which enzymes are carried by lysosomes?

  1. Endolytic

  2. Exolytic

  3. Hydrolases

  4. Hydrolytic


Correct Option: D
Explanation:

Lysosomes carry hydrolytic enzymes.

Which of the following options is the correct match of the type of cell and cell structure present in it?

  1. Animal cell - plastids

  2. Plant cell - mitochondria

  3. Animal cell - cell wall

  4. Plant cell - centrosome


Correct Option: B
Explanation:

Animal cells do not have plastids and cell wall. Similarly, plant cells do not have centrosomes. Thus, option (2) is the only correct match.

Which of the following is not a component of cytoplasm?

  1. Mitochondria

  2. Ribosome

  3. Nucleus

  4. Cytosol


Correct Option: C
Explanation:

Nucleus is not a part of cytoplasm. Cytoplasm includes only cytosol and cell organelles.

Why does RER look rough under a microscope?

  1. Due to the presence of starch granules

  2. Due to the presence of fat molecules

  3. Due to the presence of vacuoles

  4. Due to the presence of ribosomes


Correct Option: D
Explanation:

RER looks rough when viewed under a microscope due to the presence of ribosomes on its surface.

Which of the following organelles help(s) in the formation of lysosomes?

  1. ER

  2. Golgi bodies

  3. Mitochondria

  4. Both (1) and (2)


Correct Option: D
Explanation:

Both ER and Golgi bodies help in the formation of lysosomes.

Which of the following helps in detoxification of poisons?

  1. Endoplasmic reticulum

  2. Ribosomes

  3. Lysosomes

  4. Plasma membrane


Correct Option: A
Explanation:

Smooth endoplasmic reticulum detoxifies poisons and drugs.

Which of the following cell organelles manufacture(s) proteins?

  1. Golgi apparatus

  2. Ribosomes

  3. Mitochondria

  4. Lysosomes


Correct Option: B
Explanation:

Ribosomes manufacture proteins.

Which of the following structures of mitochondria provide(s) large surface area for cellular respiration?

  1. Matrix

  2. Outer membrane

  3. Cristae

  4. Cisternea


Correct Option: C
Explanation:

Cristae provide large surface area for cellular respiration.

Which cell organelle(s) has/have their own DNA?

  1. Plastids

  2. Mitochondria

  3. ER

  4. Both (1) and (2)


Correct Option: D
Explanation:

Both plastids and mitochondria have their own DNA, besides nucleus.

Which of the following is a correct difference between a plant cell and an animal cell?

  1. An animal cell is larger than a plant cell.

  2. A large vacuole is centrally located in animal cells but many small vacuoles are scattered in plant cells.

  3. Plant cells can withstand much greater changes in surrounding medium than animals cells.

  4. In plant cells, nuclear membrane is absent but cell wall is present whereas it is opposite in animal cells.


Correct Option: C
Explanation:

Plant cells have rigid cell wall which helps them to withstand much greater changes in surrounding medium.
