Weekly Quiz Competition

Question 1
1 / -0

The function(s) of rough endoplasmic reticulum is/are

A
packaging of materials

B
transport of materials

C
synthesis of proteins

D
All of the above

Solution

Rough endoplasmic reticulum has ribosomes attached to its surface. These ribosomes are responsible for synthesis of proteins. Hence, the main function of RER is protein synthesis.
Question 2
1 / -0

Which among the following is not a function of endoplasmic reticulum?

A
It synthesises lipids.

B
It provides surface for some biochemical activities.

C
It detoxifies poisons and drugs.

D
It manufactures lysosomes.

Solution

Lysosomes are manufactured and budded into the cytoplasm by the Golgi apparatus.
Question 3
1 / -0

Why do Golgi bodies have connections with the membranes of ER?

A
To prevent the membranes from mechanical injury

B
To store and dispatch the materials synthesised by ER

C
To form lysosomes in ER

D
To transport ribosomes into ER

Solution

Golgi bodies are attached to the membranes of the ER. The materials synthesised by the ER are transported to the Golgi bodies, where these are modified and then dispatched. The material may be stored in the Golgi bodies if required.
Question 4
1 / -0

Which of the following organelles have their own DNA and ribosomes?

A
Mitochondria and Golgi apparatus

B
Mitochondria and plastids

C
Endoplasmic reticulum and plastids

D
Mitochondria and lysosomes

Solution

Mitochondria and plastids have their own DNA and ribosomes. These are, therefore, called semi autonomous organelles.
Question 5
1 / -0

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

A
Animal cell: Plastids

B
Plant cell: Mitochondria

C
Animal cell: Cell wall

D
Plant cell: Centrosomes

Solution

Centrosomes are cell organelles that are exclusive to animal cells and perform a key role in cell division. Plastids and cell wall are exclusive to plant cells.
Question 6
1 / -0

Which of the following is a correct pair of organelle and its function?

A
Mitochondria - Production of ATP

B
Golgi body - Synthesis of protein

C
Lysosome - Synthesis of fats and lipids

D
Ribosome - Destruction of foreign substances

Solution

Mitochondria are known as the powerhouses of the cell. The energy required for various chemical activities needed for life is released by mitochondria in the form of ATP (Adenosine triphopshate) molecules.
