3

What is the cell membrane composed of?

Phospholipids
Proteins

4

Function of proteins?

Create gaps called pores
Pull chemicals through membrane
Take part in immune system
Cells can be identified by their surface proteins

5

What is the nucleus?

Control centre of cell
Contains DNA and proteins

6

What are chromosomes?

DNA and protein

7

What is the nucleolus?

Area of nucleus that stains darker
Makes chemicals: RNA

8

What is cytoplasm?

Between nucleus and cell membrane
Gel-like liquid containing water with salts and other organelles
Most metabolic activity happens here

9

What is the vacuole?

*Plant cell
Has a membrane
Filled with cell sap
(Contains sugar and salt)
Pushes other contents to edge of cell

10

What are chloroplasts?

*Plant cell
Contain chlorophyll
Photosynthesis takes place here

11

What are mitochondrion?

Double membranes
Function: aerobic respiration
Contain DNA and make copies of itself

12

What are ribosomes?

Float in cytosol
Produce protein

13

Name of cell that does not contain a nucleus?

Prokaryotic cell
Eg. Bacteria

14

Cell that contains a nucleus

Eukaryotic cells
