QUICK CONCEPT REVIEW
As we know plants are living things. A plant consists of different parts such as roots, shoots, stem, leaves, fruits, flowers etc. Each part of a plant plays a very important role. Let us understand these roles in detail:
It is that part of the plant develops inside the soil. Roots absorb water and minerals from soil and sends it to the other part of through stem.
Stem gives support to upper part of the plants. Water and dissolved nutrients from the soil travel up through stems. Food from leaves come down to roots by stems.
Leaves of different plants can have different shapes and sizes. Generally they are green, in coulor. In this part of the plant, food is produced by the help of sunlight. We eat the leaves of many plants for example: cabbage spinach etc.
They are the most colorful and beautiful part of the plant that produces fruit. Flowers attract human and insects because of their fragrance. They are the reproductive part of the plants.
For example Rose, Sunflower.
They come out from flowers. They are the edible part of plant. We eat fruits like Apple, Banana, Orange, Grapes etc.
It is the part of plant from which a baby plant grows. Seed contains food.
Types of Plants
We see many types of plans in our environment like big and tall plant, herbs, shrubs, climbers. Each of these types of plants have different features. Let us study these features in detail.
These are the small plans with soft stem. They have medicinal value as well. For example: Mint, Tulsi, Coriander etc.
5th june is world Environment Day. Plant a few saplings in your school or at home. Look after the plant as it grows into a tree. It may bear fruit and gives shade to all.
They are smaller than trees. They have a short stem of lower heights. Some shrubs contain flowers.
For example: Sunflower plant, Rose plant.
Big plants are called trees. They are tall and have long branches. They have stronger and thicker stems in comparison to the other plants.

Plants with weak and soft stem that need support of other plants, stick or walls etc are called climbers.
For Example: Money plant, grapevine,
Plants with weak stem that grow along the ground are called creepers.
