Plants have four main parts: roots, stems, leaves, and flowers. Roots hold the plant in the ground and absorb water and minerals from the soil through osmosis. Water and minerals are transported through the stem to the leaves where photosynthesis occurs to produce energy for the plant's growth. Plants need sunlight, water, healthy roots, stems, and leaves in order to grow properly. Temperature also affects plant growth. Roots come in different shapes depending on the plant type and serve functions like anchoring, absorbing water and minerals, storing food, and reproduction through vegetative propagation.

3. Learning
objective
Know that plants have roots, leaves, stems and flowers.
Know that plants need energy for light for growth.
Plants need water and light to grow.
Water is taken in through the roots and transported through
the stem.
Plants need healthy roots, leaves and stems to grow.
Understand how temperature affects the growth of plants.

4. What are the
parts of the
plant?

7. ROOTS
•Roots hold plants firmly to
the ground.
•Roots absorb or take in water
from the soil.

8. Types of
roots

10. Function of roots
• Anchoring: Roots are the reason plants remain attached to the ground. They
support the plant body, ensuring that it stands erect.
• Absorption: Primary function of the roots is to absorb water and dissolved
minerals from the soil. This is crucial as it helps in the process of photosynthesis.
• Storage: Plants prepare food and store in the form of starch in the leaves, shoots
and roots. Prominent examples include carrots, radish, beetroot, etc.
• Reproduction: Even though roots are not the reproductive part of plants, they are
vegetative parts. In some plants, the roots are a means of reproduction. For
instance, new plants arise from creeping horizontal stems called runners (stolon's)
in jasmine, grass, etc. This type of reproduction is called vegetative propagation.
• Ecological Function: They check soil erosion, provide sustenance and habitat to
various organisms.
