Roles of Organelles

Question 1

Nucleus

Answer 1

The nucleus serves as the repository of genetic information and the control center

Question 2

Ribosomes

Answer 2

A ribosome is an intercellular structure made of both RNA and protein, and it is the site of protein synthesis in the cell

Question 3

Rough endoplasmic reticulum

Answer 3

The RER is associated with many roles in protein synthesis, which also include post-translational modifications, folding, and sorting.

Question 4

Smooth endoplasmic reticulum

Answer 4

Its main function is the synthesis of lipids, steroids, and carbohydrates, as well as the metabolism of exogenous substances, such as drugs or toxins.

Question 5

Golgi apparatus

Answer 5

The Golgi apparatus, or Golgi complex, functions as a factory in which proteins received from the ER are further processed and sorted for transport to their eventual destinations: lysosomes, the plasma membrane, or secretion

Question 6

Chloroplasts

Answer 6

Chloroplasts produce energy through photosynthesis and oxygen-release processes, which sustain plant growth and crop yield. (Only found in plants)

Question 7

Mitochondria

Answer 7

The classic role of mitochondria is generating ATP by utilising the energy released during the oxidation of the food we eat.
