What are the 2 main cell categories?

Answer 1

Eukaryotic - Any cell that has a nucleus. E.G. Plant/animal cells.

Prokaryotic - A cell that hasn’t got a nucleus. E.G. Bacteria.

Question 2

Nucleus

Answer 2

Contains DNA which carries the genetic code for making enzymes and other proteins used in chemical reactions such as photosynthesis and respiration.

Question 3

Cell wall

Answer 3

Made from cellulose fibres. Strengthens the cell and supports the plant.

Question 4

Cell membrane

Answer 4

Allows gases and water to diffuse freely into and out of the cell. Controls the transport of other molecules.

Question 5

Cytoplasm

Answer 5

Where enzymes and other proteins are made. Location of reactions in anaerobic respiration.

Question 6

Vacuole

Answer 6

Filled with cell sap to help support the cell.

Question 7

Mitochondria

Answer 7

Contains enzymes for the reactions in aerobic respiration (in animals, plants and yeast).

Question 8

Chloroplast

Answer 8

Contains the green pigment, chlorophyll, which absorbs light for photosynthesis, and the enzymes needed for photosynthesis.

Question 9

Ribosome

Answer 9

Where amino acids are joined together to make a protein.
