Then one day I looked at the seed and found a hair like structure was also growing in the form of root even under the soil and in few days a web of roots was formed inside the soil. Now a small bud came out. As the plant grew, its stem became thick and dark in colour. Many branches of the plant came out from the stem. Now flowers came on the plant and butterflies, bees, bumblebees etc. started coming and sitting on those flowers. These insects do the work of pollination.

A seed came out inside the fruit that when buried into ground the same process starts again.

Long Answer/Essay Type Questions-

Question 1.
How does seed germination take place? Explain with diagram.
Answer :
When the seed is buried in the soil, it grows thicker by absorbing air and water that had gathered between soil particles and finally it swells and bursts. Then a tiny hairlike structure starts emerging from seed which keeps on growing. This is called germination of the seed. It is shown in the following picture-

Question 2.
How does the root system develop?
Answer :
After the germination of the seed a tiny white structure moves down wards making its way through the soil particles. At the same time many similar structures emerge from its side, absorb water, air and nutrients among the soil particles and grow rapidly and turn into web-like structure inside the ground. This is how the root system develop.

Question 3.
How does the sprouting system develop?
Answer :
The stem, branches and leaves present in the upper part of the plant are called sprouting system. A small bud comes out of the seed and grows upwards. After getting nutrients from pulses it comes out of the ground into the sunlight. Now leaves come out from that bud which turn green after getting sunlight. The stem becomes thick and dark in colour. Then many branches and leaves come out on that stem. In this way the sprouting system develops.
