Site of photosynthesis

Question 3

Description and function of Golgi apparatus

Answer 3

Fluid filled membrane bound flattened sacs
Process and packages lipids and proteins
Also makes lysosomes

Question 4

Answer 4

Fluid filled sacs

Stores lipids and proteins that have been produced and transports them out of the cell

Question 5

Description and function of lysosomes

Answer 5

Round organelle, type of Golgi vesicle

Folds and processes proteins made at the ribosomes

Question 8

Description and function of smooth endoplasmic reticulum

Answer 8

No ribosomes

Synthesises and processes lipids

Question 9

Description and function of cell wall

Answer 9

Rigid structure made of cellulose, in fungi it’s made of chitin
Supports cells and prevents them from changing shape

Question 10

Description and function of vacuoles

Answer 10

Membrane containing cell sap

Helps to maintain pressure in the cell and keep it rigid so it doesn’t wilt
