Basic structure of plants New words


stem – plant part that supports the leaves, fruit and flowers


leaf – green, flat plant part that catches the sunlight


flower – plant part that holds male and female parts


fruit – fleshy plant part that forms from a pollinated flower; it contains the seeds


seed – small plant part from which a new plant will grow


root – underground plant part that anchors the plant in the soil and takes in water


Look at the picture of the plant in Figure 1. It has a typical plant structure with six important parts: • Roots branch underground. They hold the plant firmly in the soil.


• The stem is usually stiff and straight like a rod. It holds the leaves, fruit and flowers.


• The leaves are green and flat. They catch the sunlight. • The flowers are pretty. They hold the male and female parts for reproduction.


• Fruit grows from pollinated flowers. The fruit holds the seeds.


• Seeds are small and dry out. Seeds are new plants in a little package.
