in this lesson
How do the structures of a plant use water, air and light to perform life processes?
• Plants have roots, stem, leaves and sometimes flowers or fruit.

• Plants use these specialized structures to obtain their basic needs of water, air
and light.

• Each part of a plant has its own function, where the roots help the plant get water
and nutrients from the soil and the other parts of the plant help it survive.

What does a plant need to survive?
• Plants use structures that are unique among living organisms to produce their own food using sunlight.
• When a tree is planted, it begins to grow from a seedling into a mature tree depending on some resources such as water, air and sunlight to make its food to survive.

Note :
►Plants need water, air, sunlight and nutrients from soil as basic needs to live and grow.
►Water and air are basic needs of plants, animals and humans.
►Humans and other animals need to eat food to gain energy and nutrients to live
and grow.
►Most plants get nutrients from soil and make their own food through a process
known as "photosynthesis" that takes place in the plant leaves.

Plant Needs
• Plants need some resources to live and grow such as:
Nutrients. - Water.
Carbon dioxide gas (a gas found in the air). - Sunlight.

Note :
Soil is not a basic plant need because:
Ex : Some plants only grow in the water

Plants and Food
• Plants make their own food which is a type of sugar that provides the plant with energy to grow.
•Plants make their food in their leaves by means of photosynthesis process :
The roots of a plant absorb water and nutrients from the soil.
Water and nutrients are carried from the roots to the leaves through the stem.
