In Human life Plants plays an important role. They provide
following to human:-
1.
Oxygen
2.
Food
3.
Medical Benefits
4.
Cloths
Apart from human being these provide shelter to animals and
birds. Without Plants life is impossible.
There are following parts of plants:-
1.
Roots
2.
Stem
3.
Leaves
4.
Fruits
5.
Flowers
Parts of Plant |
Now let’s discuss about them:-
1. Roots:- Roots are underground part of
plants, They provide strength to plant to stay intact to earth in its position.
More deeper the roots are more strength it provides to plants. They provide water requirements of plants as
they absorb water and mineral from the soil. Whenever we provide water to
plants it is get passed to plants only through its roots. They act as heart of the plant and they are
main part for photosynthesis of plants.
When plants get
converted into trees then these roots get even deeper to earth to reach out at
water level of plants from where these absorb the water requirement of tree.
2.
Stem:-It
is part of plant which is above the ground and when plants are get converted into
trees its stem colour changed to brown and for smaller plants stems are green
in colour. This is the basis of shoot system and at stems flowers, leaves and
fruits are grown. The part of stem where leaves and fruit are grown is known as
node and the area between the node is known as internodes.
From roots Food, water and minerals will
reach to other parts of plant through stem only. They will store the excess
food made by plants in the form of starch. Apart from flowers, leaves and fruits few
stems even have thorn around the stem which protect the plants from animals and
birds. Stems also help in reproduction e.g. if we cut the few barks of plants
these will regrown after a few time which is known as reproduction and even few
plants stems are used in plantation of new plants.
3.
Leaves:-
These are smaller but yet most important part of plant as leaves contains chlorophyll
which helps the plants to prepare food during photosynthesis. There are following parts of leaves:-
(i)
Petiole
(ii)
Leaf base
(iii)
Lamina
Petiole will
keep the leaf cool by exposing the leaf blade to environment from where leave
remains in touch with air.
Leaf base is an expanded
part of leaf.
Lamina of the leaf contains veins which
provide strength to the leaf blade and also help in providing water and
minerals upto leaves.
Apart from chlorophyll leaves also plays
important role in removal of excess water from plants through tiny pores known
as stomata. Further leaves also help in reproduction.
Leaves also beatify the plants and serves
as important food for animals.
4.
Fruits:-
Some plants
along with leaves and flowers also produce fruits.
5. Flowers:”-
Flowers are reproductive
part of plant and these beautify the plant. There are following parts of
flowers:-
(i)
Petals
(ii)
Stamens
(iii)
Sepals
(iv)
Pistil
Petals attract the
insects and birds being a most beautiful and colourful part of plant.
Stamens are the
male part of flower it consists of anther and filament.
Sepal are the part
which is under petal and is green leafy part and this protects the flower buds
from getting damaged.
And Pistil is
female part of the flower which consists of stigma, style and ovary.
