Chapter 1: Plants Around Us
Normally all plants are associated with the colour green. Thus, we use the term ‘Greenery’ commonly for plants. Plants give us fresh air, food and wood for various purposes. Plants are found in different shapes and sizes. Some plants are small and some are big. Big plants usually grow high. Some plants are weak and some are strong. Almost all green plants prepare their own food.

Trees
Trees are tall plants with woody trunks.
Trees are strong. Most trees have branches.
Some trees bear flowers and fruits, some trees may not.
The roots of trees penetrate deep into the soil. Trees can live for years.
Example : mango tree, peepal tree, banyan tree, pine tree.
Assignments:
1. Read Pages 6 and 7.
Shrubs have thin and woody stems. They have many branches.
So they look bushy. Most shrubs live for years.
Example : rose, hibiscus, sunflower and cotton.
Herbs
Herbs have thin, soft and green stems. They are smaller than shrubs. They have no wood. Many herbs have medicinal use. Herbs live for a few months only.
Example : brinjal, tulsi, mint and spinach.

Herbs have thin, soft and green stems. They are smaller than shrubs. They have no wood. Many herbs have medicinal use. Herbs live for a few months only.
Example : brinjal, tulsi, mint and spinach.
Climbers have thin, long and weak stems.
They need support as their weak stems cannot bear the weight of the plant.
Life of such plant varies with nature.
Example : grapevine, money plant, bean and pea plant.
Some plants have weak and thin stems.
These plants bear heavy fruits.
They cannot climb without support.
Hence, they creep on the ground.
These plants are thus called creepers.
Creepers live for one season only.
Example : watermelon, pumpkin and bottle guard.
Thorny Plants
Some plants have sharp, woody and pointed structures.
These structures save them from enemies.
Such plants are known as thorny plants.
Example : rose, cactus.
