The seed contains an embryo - a group of cells ready to form roots, a stem and the first leaves. Once the coat around the seed is moistened, the embryo cells expand and burst out in a process called germination.

First, the roots will develop and push out and down into the soil to make sure the new plant can get water. Then the stem cells stretch up to display the first leaves.

The embryo uses food stored in the seed to power its initial growth until the leaves can start producing food. Small seeds don’t have much stored food so they have to fall in just the right spot to be successful. The parent tree has some ways to improve the chances of its seed finding the right spot, like dropping seeds after a bushfire has made the ground bare and free from other plants that would use all the water and nutrients.

Once the roots are in the soil and the first leaves are in the sun, the plant is ready to really start growing.

People stop growing after they’ve become grown-ups but trees just keep getting taller and thicker however long they are alive.

Grass, bamboo and many other plants grow from the bottom up, so if you put a mark on the stem and come back in a little while, that mark will have been pushed further above the ground. But if you put a mark or even nail a board into a tree at one metre above the ground then come back in 10 years, it will still be only one metre above the ground. That’s because trees grow from the outside at the top and the tips.

Hi friend..
Here is your ANSWER


➡️✴️✴️ANSWER✴️✴️⬅️



the water is promoting the seed to germinate the sleeping tissues will be activated and the embryo that was dormant will wake up and germinate the all powerful parenchyma will take initiation to transform into what ever the part of plant is supposed to become..endosperm or the reserve food substance that are present in the seed will form the plant… what we eat as wheat and rice are nothing but the endosperm of the mono cot seeds and the coconut also… what we eat as pulses are the proteinaceous part of the cotyledons for germination of the seeds so water and the temperature plays an important role for the formation of another seed or life as such..water is called the elixir essential for life ..



I HOPE IT WILL HELP
