1

animal and plant cells are examples of E..

Eukaryotes

2

Eukaryotes are complex organisms often described as M

Multicellular

3

Bacterial cells are P...

prokaryotes

4

Prokaryotic cells do not have...

a nucleus or mitochondria

5

prokaryotic cells compared to eukaryotic cells are

smaller, single celled, have rings of DNA called plasmids

6

Groups of bacterial cells are called

colonies

7

What does an animal cell not have that a plant cell has?

cell wall, vacuole and chloroplasts

8

Function of the cell membrane

controls what enters and leaves the cell

9

Function of the nucleus

Controls the cells activities and contains the genetic material (DNA)

10

Function of the cell wall

Provides support to the plant, made of cellulose

11

Function of bacterial plasmids

provide bacteria with variation - usually conferring antibiotic resistance

12

Function of the ribosomes

protein synthesis - its a very small organelle

13

Function of the mitochondria

Site of respiration, energy is released here

14

Describe the feature of bacterial DNA

Circular/loop, not arranged into chromosomes and not found in a nucleus

15

All eukaryotic cells have

a nucleus

16

An organelle is

a part of the cell with a specific function

17

The cytoplasm

is mainly water and is where the chemical reactions occur

18

Substances move in and out of cells by

diffusion

19

In exchange of materials between cells and their environment, substances must cross the

cell membrane

20

All our cells require

glucose and oxygen

21

All our cells carry out a process called R...

respiration

22

We can view cells using a

light microscope

23

Respiration is

is a chemical reaction that occurs inside all your cells to release energy

24

DNA in eukaryotic cells is arranged into C...

chromosomes

25

Plants have chloroplasts because

they need to photosynthesise

26

The function of the chloroplasts are

to trap light energy for photosynthesis

27

Photosynthesis is

when plants trap light energy and react carbon dioxide and water to produce glucose and oxygen

28

The colour of chlorophyll is

green

29

chlorophyll is found in the

chloroplast

30

cell wall is made of

cellulose
