2.1 Cell Structure & Function

Question 1

What are the components that can be found in a plant cell but not in an animal cell ?

Answer 1

• chloroplasts

- cell wall

Question 2

The function of ROUGH Endoplasmic Reticulum (RER) .

Answer 2

• transports protein synthesised from ribosomes

- excreted protein will be transported (by transport vesicles) to the other part of the cell.

Question 3

Function of SMOOTH Endoplasmic Reticulum (SER)

Answer 3

A site for

• lipid synthesis
• detoxification
• steroid hormone production

Question 4

Function of Lysosomes

Answer 4

• breaks complex organic materials (proteins, lipids, nucleic acids)
• involved in digestion process & defense metabolism

Question 5

Function of Golgi apparatus

Answer 5

• processes & modifies Carbohydrates, Proteins, Glycoproteins
• (those above) are transported (by secretory vesicles) to other cell parts

Question 6

Function of Chloroplasts

Answer 6

• absorbs & converts sunlight to chemical energy

- for photosynthesis
