B1.1 Cells - Animal, plant and bacterial cells

Question 1

Animal Cell

Answer 1

Type of cell with a nucleus, cell membrane and mitochondria but no chloroplasts or cell wall

Question 2

Plant cell

Answer 2

Type of cell with a nucleus, cell membrane, mitochondria, chloroplasts, a cell wall and a permanent vacuole

Question 3

Bacterial cell

Answer 3

A cell type with a cell wall but no nucleus, where the genetic material is free within the cytoplasm and sometimes within plasmids

Question 4

Cell membrane

Answer 4

Controls the entry of substances into and outside of the cell, found in animal, plant and bacterial cells

Question 5

Nucleus

Answer 5

Contains genetic material in an animal or plant cell

Question 6

Ribosomes

Answer 6

Where protein synthesis takes place

Question 7

Cytoplasm

Answer 7

A jelly-like substance that contains organelles and is where chemical reactions take place, found in bacteria, plants and animals

Question 8

Mitochondria

Answer 8

Where cellular respiration takes place in animal and plant cells

Question 9

Permanent vacuole

Answer 9

Space in the cytoplasm filled with cell sap found in plant cells

Question 10

Plant cell wall

Answer 10

Outside later of cellulose which strengthens and supports plant and algal cells

Question 11

Bacterial cell wall

Answer 11

An outer layer of bacterial cells that, unlike plant cells, is not made of cellulose

Question 12

Plasmids

Answer 12

Small rings of extra DNA found in bacterial cells

Question 13

Chloroplasts

Answer 13

Contains chlorophyll and is where photosynthesis takes place in plant cells

Question 14

Chlorophyll

Answer 14

A green pigment found in the chloroplast that absorbs light energy used to carry out photosynthesis

Question 15

DNA loop

Answer 15

A single molecule of DNA that is found free in the cytoplasm of bacterial cells

Question 16

Flagella

Answer 16

A long, whip-like filament that allows certain bacterial cells to move
