Plants can be classified into three groups: grasses, bushes, and trees. Grasses have soft, thin stems and are usually short, while bushes are taller and have many woody stems and branches. Trees have thick, woody trunks. Deciduous trees lose their leaves in autumn, while evergreen trees keep their leaves year-round. Photosynthesis is the process by which plants make their own food, using water, minerals, carbon dioxide, and sunlight.

We can classify plants into 3 groups: GRASS BUSHES TREES
PLANT LIFE Grasses have a soft stem. Thy are thin, bendy and usually short. GRASSES
Busses are taller than grasses. Bushes have a lot of woody stems with low branches. The blackberry bush has lots of long branches BUSHES
Trees have a thick, woody stem called a trunk. TREES
Deciduous trees lose their leaves in autumn. Oak trees are decidious.
Evergreen trees produce leavesallyear round. Spring Summer Autumn Winter Pine trees are evergreen
PHOTOSYNTHESIS How plants make their own food
Plants need water, minerals, light and energy from the Sun and carbon dioxide to make their own food. Water Sunlight Minerals Carbon Dioxide
Plants make food in their leaves.
The roots absorb water and minerals from the soil.
The water and minerals travel up the stem to the leaves.
The leaves absorb carbon dioxide from the air through small holes. Carbon dioxide
Using energy from the Sun, the carbon dioxide combines with water, minerals and sunlight to make food. During the process of photosynthesis, plants release oxygen into the air.
