Nerve tissue

11

Identify 3 plant organs

Leaf - absorbs light for photosynthesis

Stem - holds plant upright

Root - anchors plant into ground and takes in water/minerals.

12

List 3 examples of specialised cells.

Red Blood Cell

Nerve Cell

13

What is an organ?

An organ is a gorup of tissues that work together to perform a certain function.

E.g. the digestive system contains many organs to digest food.

14

What is a tissue?

A group of similar cells working together to perform a specific function (job).

e.g. muscle tissue - contracts to allow movement.

15

What is the funciton of the following organ: brain

controls the body

16

What is the funciton of nerve tissue?

To transmit messages around the body.

What is the funciton of the following organ: liver

Removes toxins (poisons) from the blood

Produces bile to help digestion

23

24

What is meant by a specialised cell?

A cell that has adapted speciali features to carry out a specific function (job).

e.g. sperm cell has a tail to swim to the egg
