A science article explaining what plants need to live and grow. Photosynthesis is introduced as the requirement to provide sufficient carbon dioxide, water and sunlight to enable plant growth. It is also explained how plants need space and sufficient soil in which to grow their roots.

This article explains how the veins in leaves and stems circulate water, nutrients and energy round the plant; how the ‘stomata’ of leaves are frequently open during the day but shut at night; how carbon dioxide enters leaves through the ‘stomata’; looking at stomata through an electron microscope; an introduction to how leaves use carbon dioxide, light and water to make ‘food’.
In this science article we describe what trees are; we learn to identify different parts of a tree including their leaves, boughs, twigs, trunks and roots; we describe different sizes of trunk and different types of leaf including ‘broad’ leaves and needles; we think of reasons why trees have bark including how bark stops trees getting diseases ; we suggest other weblinks about trees
