PLANTS
Photosynthesis    Sexual reproduction   Asexual reproduction


Plants differ from animals in the way they obtain food:

The only way an animal can obtain food is by eating something  that is (or used to be) alive. 
A plant can manufacture food using simple chemicals from the environment.
This process is called photosynthesis and is unique to the plant kingdom

Structure of a flowering plant
ROOT Absorbs water and dissolved mineral salts from the ground. Supports the plant.

STEM Transports food and water around the plant. Holds apart the leaves and flowers.

LEAVES Where photosynthesis is carried out. Have a large surface area to absorb the sunlight.

FLOWER Contains the reproductive organs. Where the plant makes seeds. Flowers that are insect pollinated (eg rose) have colourful or scented petals to attract insects. Wind pollinated plants (eg grass) do not have petals but still have flowers.
