Life cycle of a plant.
A plant goes through many stages in its life cycle and we are going to show you all of them.
1.Seed is in the ground
Seed is in the ground.
2.Plant grows roots
Soon the plant grows roots.
3.Seed cuts open
After the plant has had a lot of sunlight and and water the seed won't be able to hold the plant any more so the seed cuts open, grows a leaf or two. The roots get stronger as well.
4.Plant grows taller and stronger
Now the plant grows more leaves and the roots get stronger and the stem becomes stronger so it can hold more water for the leaves.
5.Plant has a flower
Soon the plant will grow a wonderful flower.
Here is the interesting bit.So every flower has a stamen (male reproductive part of the flower) and a carpel (female reproductive part of the flower). The stamen consists of a thin stalk called filament and a two lobed head containing two pollen sacs in each lobe which are filled with pollen.Pollen is the male reproductive part of a flower.The carpel consists of three parts,a stigma,a style and the ovary,which contains small structures called ovules,which are the female reproductive part of the flower.So when pollen grains fall on the stigma,they fall down the tube of the carpel called style and reaches the ovary,where the pollen grains fuse with the ovules and the ovary grows into a fruit and the ovules grow into seeds,which are protected by the fruit.The other parts of the flower dry up and fall off.This is called pollination.
Seed dispersal is an important method of spreading seeds so that once the plant is old and is drying up,the seeds don't fall near the plant's roots,thereby preventing too much plant space.
