1

What do cells become to their function

specialised

2

What do cells that require a lot of energy have lots of

mitochondria

3

What do cells that make lots of proteins have lots of

ribosomes

4

What is an example of a specialised cell and its feature

epithelial cells absorb food, so have villi and micro-villi to increase SA:V, and lots of mitochonfria for energy for transport

5

What are specialised cells grouped together to form

tissues

6

What are tissues

a group of cells working together to perform a particular function

7

What is an example of tissues and what are they composed of

epithelial tissue (made up of epithelial cells)

8

What do tissues work together to form

an organ

9

What is an example of an organ and what is it composed of

the stomach, composed of epithelial tissue, muscular tissue and glandular tissue

10

What do organs work together to form

an organ system

11

What are 3 examples of an organ system

the digestive system, respiratory, circulatory

12

What stage are all cells the same

when they are embryos

13

How are all cells in an organism produced from and what does this mean

mitotic division, they all contain the same genes

14

Why are some cells different if they all contain the same genes

only certain genes are switched on in each cell

15

What 2 functions do epithelial tissues have

1) protective
2) secretory

16
