1

What are the structures, such as a nucleus, know as in every cell?

Subcellular structures

2

Are all cells the same?

No

3

Why might a cell be different?

Depending on what the cells job is and the organism they are from.

4

How many cells is bacteria made up of?

One cell

5

What is the correct scientific term for an organism with more then one cell?

A multicellular organism

6

What are the 2 main types of cells called?

Eukaryotic cells and Prokaryotic cells

7

What type of cells are plant and animal cells?

Eukaryotic cells

8

What type of cells are bacterial cells?

Prokaryotic cells

9

Do Eukaryotic cells contain a nucleus?

Yes

10

Do Prokaryotic cells contain a nucleus?

No

11

Where is the genetic material in Prokaryotic cells?

Floating in the cytoplasm

12

Which type of cell is larger Prokaryotic or Eukaryotic?

Eukaryotic cells

13

Which type of cells are simple cells, Prokaryotic or Eukaryotic?

Prokaryotic cells

14

Which type of cells are complex cells, Prokaryotic or Eukaryotic?

Eukaryotic cells

15

Roughly how big is a Eukaryotic cell?

Between 10μm and 100μm

16

Roughly how big is a Prokaryotic cell?

Between 1μm and 10μm

17

What subcellular structures do all Eukaryotic cells contain?

A nucleus(at some stage of their development), cytoplasm, a cell membrane and mitochondria

18

What is the function of a nucleus?

To control the activities of the cell

19

What two things does the nucleus contain?

The organisms genetic material, arranged as chromosomes. And instructions on how to make new cells or new organisms.

20

What does the genetic material in a cell determine?

The cells appearance and function

21

What is the plural for mitochondrion?

Mitochondria

22

What happens in the mitochondria?

Cellular Respiration, enzymes, enable glucose and oxygen to react together, the reaction transfers vital energy to the organism.

23

What is the function of a cell membrane?

A selective barrier that controls which substances pass into and out of the cell.

24

What does the cell membrane also contain?

Receptor molecules

25

What happens in the cytoplasm?

Chemical reactions that keep the cell alive

26

Name the extra subcellular structures in plant cells.

A cell wall, a vacuole and chloroplast

27

What do chloroplast contain?

Chlorophyll

28

What does chlorophyll do?

Transfers energy from the sun to the plant as light, which is used in photosynthesis

29

Where is chloroplasts found in a plant?

Only the green parts of a plant

30

What is the vacuole full of?

Cell sap, a watery solution of sugar and salts

31

What is the function of the vacuole in a plant cell?

It helps keep the cell rigid, and this supports the plant and keeps it upright

32

What is the cell wall made of?

Tough fibre called cellulose

33

What is the function of the cell wall?

It makes the wall rigid and supports the cell

34

What is the correct scientific term for a singular cell organism?

A unicellular organism
