Question 5

Function of cell membrane

Answer 5

Semi permeable

Separates the cell from the outside

Cell wall function

Answer 6

Rigid shape and defined shape

Gives support and strengthens the cell

Question 7

Function and appearance of Cytoplasm

Question 11

Ribosomes structure and function

Answer 11

Red circular dots

Function: to make protein

Question 12

Chloroplast function and structure

Answer 12

Photosynthesis

Lamella
Granium- light stage of photosynthesis(contains chlorophyl)
Stroma- dark stage
Outer membrane

Question 13

Vacuole what are they and their function

Answer 13

Membrane bound sacs within the cytoplasm.
Contains fluid called cell sap.(salts,sugar and pigments)

Function: storage, support, waste disposal, protection and growth.

Question 14

Nucleus function and parts. Diagram

Answer 14

Controls activities of cell.

Nucleolus: makes ribosomes
Double nuclear membrane: semi permeable
Nuclear pore: passageway
Chromatin: contains DNA
Nucleoplasm: holds parts of nucleus together.

Question 15

Cell membrane diagram

Answer 15

Phospholipids
Phosphate head
Lipid tail
Proteins

Phospholipids form a bilayer.
Protein on inside/outside/whole way through.

Question 16

Cell wall structure

Answer 16

Made of rigid carbohydrate- cellulose, strengthens and protects

Mineral calcium for healthy cell walls

Question 17

Def. of Eukaryotic

Answer 17

Organisms whose cell contains a nucleus and other membrane bound organelles.
Eg. Plant and animal cells

Question 18

Def. of prokaryotic

Answer 18

Organisms whose cells don’t contain a nucleus or other membrane bound organelles.

Eg. Bacteria cell
