Plants grow almost everywhere on Earth.they give us food to eat,keep the air fresh and make the world look beautiful.without them, animals could not live.now find out more about the different types of plants and different parts of plants.
Types of Plants :
now that you know how plants are classified according to the type of stem they have,arrange the following plants under the correct heading.
Parts of Plant:
The Root:This part of the plants grows under the ground.it absorbs water and minerals from the soil.It fixes the plant to the soil.
Roots are of two types-Tap Root and Fibrous Root.
The Stem:This part of the plant grows above the ground.It helps the plant to stand firm.It bears leaves,flowers and fruits.The stem also carries water,minarals and food,prepared by the leaves,to the different parts of the plant.
There are small tubes inside the stem that help it to carry these things to the different parts of the plants.Some stems grow under the ground also .Such stems store food for the plant.
Did you know that potato,onion,ginger and garlic are not roots ,but stems!The sugrcane that we eat is actually the stem of the plant.
The Leaf-The leaves of a plant are mostly green in colour.Leaves are of different types and sizes,for example..big(banana),small(mint),feather-like(coconut).Leaves may be of different types and sizes but they have some common features.
The green colour of the leaves is because of chlorophyll.Leaves are known as the food factory of the plant. Leaves prepare food with the help of chlorophyll,water,sunlight and air.they use the carbon dioxide present in the air to prepare their food.This process is called photosynthesis.
As plants prepare food they also produce oxygen,which is released into the air.this helps to purify the air.
The Flower- This is the most attractive and colourful part of the plant.Flowes which do not have bright colours often have a pleasant smell. A flower is actually the seed-box of the plant.
You must have seen butterflies,bees and other insects visit the flowers.
what attracts them?
They are attracted by the bright colours and the pleasant scent.But why do they keep visiting the flowers again and again? Flowers have nector in them.this nector is the food for the bees and butterflies. Insects help to carry the pollen(yellow powdery substance) to other flowers.this helps the flowers to make seeds.This is called pollination.
The Flower- Fruits store seeds in them.The seeds grow into new plants.
