Function of parts of plant

What is the function of roots?

• Roots hold the plants in soil.
• Roots absorb water and nutrient from the soil.
• Roots store food for plants use.
• Roots have root hairs that help to increase the surface area to absorb water and nutrient from the soil.


What is the function of stems?

• Stems act as a transport channel for water and nutrients from roots to the leaves and for food from leaves to the roots.
• Stems also support leaves, flowers and fruits.


What is the function of leaves?

• Leaves help to make food for the plants
In the presence of sunlight, leaves take in carbon dioxide gas from the air and release oxygen gas to the air and making food for the plants. Leaves supply the oxygen gas we breathe that we need to stay alive. This process is called photosynthesis.

Photosynthesis process occurs in green leaves that contain green pigments called chlorophyll.

(in the presence of sunlight)
CO2 + H2O --> sugar + O2
Carbon dioxide + water --> food + oxygen

• Leaves also help plants to respire.


What is the function of flowers?

• Flowers are the reproductive organ in the plants.
• Flowers produce seeds used for sexual reproduction.
• Flowers are usually beautiful with bright colors and fragrant to attract insects, bees
(pollinators) for pollination. Pollination process is the transfer of pollen from anther to stigma of flowers.
• Flowers help to produce fruits and carry seeds inside for reproduction of plants.
