Plant Structures and Functions

4

Read about the function of each of the plant parts below and then label the parts of the plant on the diagram provided.

Leaf
Leaves grow directly out of the stem or on small stalks on other parts of the plant. Leaves are where food for the plant is made. The process of making food in a plant is called photosynthesis. To keep the plant cool and maintain moisture balance, leaves also release water through a process called transpiration.
Flower
Flowers grow on stems or on stalks that grow out of stems. Flowers are brightly coloured and often scented to attract pollinators, like bees. They are the reproductive part of the plant that produces fruit and, in turn, seeds.
Roots
Most roots grow underground to anchor the plant in the soil. The roots are where plants take in water and minerals. Small fibrous roots soak up water at the surface and longer taproots drill for water deep in the ground. Large, thick tap roots often store water and nutrients.
Stem
Stems are the parts of the plant that allow it to grow, or in some cases climb, taller. Some stems directly support leaves and flowers, but other stems grow as a single, main trunk that supports branches. Stems contain a transport system that allows water, minerals and sugar to move between the roots and the leaves, and vice versa.
