Questions
Which of the following is the function of smooth endoplasmic reticulum in an animal body?
- To detoxify poison and drugs in liver cells
- To synthesise proteins
- To digest the worn-out cells in the body
- To generate energy in the form of ATP
Which of the following is not a characteristic feature of mitochondria?
- They synthesise energy in a cell.
- They control and coordinate all activities of a cell.
- They possess a double membranous structure.
- They possess their own DNA and ribosomes.
Mitochondrion is called the 'Powerhouse of a cell' because
- it synthesises proteins
- it synthesises lipids
- it synthesises ATP
- it synthesises acrosome
Plastids are important for green plants because
- they trap solar energy
- they store proteins
- they synthesise energy
- they regulate cell function
Why are cristae present in the inner membrane of mitochondria?
- To provide large surface area for ATP generation
- To provide site for protein synthesis
- To provide site for attachment of endoplasmic reticulum
- To provide site for attachment of ribosomes
