The growing embryo splits the shell of the seed. Responding to gravity—whichever way the seed lies—the root probes its way toward the ground. As soon as the tiny root tip penetrates the soil, the tree is not only fixed in the ground, but is capable of absorbing water and mineral nutrients.
How does a seedling grow from such a small seed?
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.

Do bigger seeds produce bigger plants?
Large seeds outgrow small seeds. The effects of large seed size on plant growth are unanimously positive. Larger seeds produce seedlings that emerge faster, are bigger, and have better access to nutrient sources.
How does a seed grow into a new plant for Class 1?
The seed grows into a plant by the process of germination. Generally, living things need some nutrient substances to grow so seeds obtain nutrients and water from the soil and push down the roots into the soil then grow up.
Do small seeds grow into small plants?
Despite their small size, though, seeds contain food and all the instructions necessary to sprout to life as a plant. When seeds are planted, they first grow roots. Once these roots take hold, a small plant will begin to emerge and eventually break through the soil. When this happens, we say that the seed has sprouted.
What is the purpose of pricking?

What is germination of seed Class 5?
Germination: The process in which a plant emerges from a seed and begins growth is called germination. Stages of Germination: During the early stages of germination, the seedling gets the food required for its growth from the cotyledons.
