Functions of organelles

Question 1

Cell Wall

Answer 1

The main function is protecting and maintaining the shape of the cell. It also helps the cell withstand the turgor pressure of the cell.

Question 2

Chloroplasts

Answer 2

Contains an essential pigment chlorophyll which is necesary to trap sunlight or the production of glucose.

Question 3

Plastids

Answer 3

They contain RNA and DNA that allows them to synthesize necessary proteins for different processes.

Question 4

Vacuole

Answer 4

Acts as storage for nutrients as well as waste materials to protect the cell from toxicity

Question 5

Cell membrane

Answer 5

It regulates what can be allowed to enter and exit the cell, acting as a semipermeable membrane, which facilitates the exchange of essential compounds required for the survival of the cell. It provides mechanical support that facilitates

Question 5

Cell membrane

Answer 5

It regulates what can be allowed to enter and exit the cell, acting as a semipermeable membrane, which facilitates the exchange of essential compounds required for the survival of the cell. It provides mechanical support that facilitates the shape of the cell while enclosing the cell and its components from the external environment.

Question 6

Endoplasmic Reticulum

Answer 6

Contains many of the enzymes required for several metabolic processes, and the ER’s surface is essential for other operations like diffusion, osmosis, and active transport. Helps in the synthesis of lipids like cholesterol and steroids.

Question 7

Golgi Apparatus

Answer 7

The Golgi functions as a factory in which proteins received from the ER are further processed and sorted for transport to their eventual destinations.

Question 8

Mitochondria

Answer 8

Responsible for the supply and storage of energy for the cell. The oxidation of various substrates in the cell releases energy in the form of ATP (Adenosine Triphosphate ).

Question 9

Nucleus

Answer 9

The nucleus is responsible for controlling all cellular activities. Responsible for storage as well as the transfer of genetic materials in the form of RNA or DNA.

Question 10

Ribosomes

Answer 10

Ribosomes are the site of biological protein synthesis in all living organisms

Question 11

Cytoplasm

Answer 11

Site of metabolic reactions. It acts as a buffer and protects genetic materials as well as other organelles from damage due to colision or change in the ph of the cytosol
