Study Notes

Structure of a Seed

A seed consists of three main parts: seed coat, cotyledon, and embryo.
The seed coat is the outermost covering that protects the seed and helps it survive.
The cotyledon is the food inside the seed that provides energy for the young plant to grow.
The embryo is the part of the seed that develops into a new plant, including the root, stem, and shoot.

Germination

Germination is the process of a seed developing and growing into a plant.
It requires water, the right temperature, and adequate space for the roots to grow.
The process involves the seed breaking into two seedlings, with the root growing down into the ground and the shoot growing up into the air.

Seed Dispersal

Seeds can be dispersed by water, wind, animals, or humans.
Seeds dispersed by water have adaptations to help them float, such as coconut, lotus, and maple seeds.
Seeds dispersed by wind have structures that allow them to float in the air, such as dandelion seeds.
Seeds dispersed by animals have hooks that attach themselves to animals, such as mistletoe seeds.
Seeds dispersed by humans are intentionally moved to various places.

How to Grow a Plant from a Seed

Choose a healthy and undamaged seed.
Plant the seed in soil and cover it with a thin layer of soil.
Keep the soil moist and provide adequate light and warmth.
Be patient and observe the plant closely, making sure it receives the appropriate amount of water and light.
Transplant the plant into a larger pot or into the ground once it is large enough.

Exceptions to Seed Growth

Some plants, such as carrots, sweet potatoes, and turnips, grow from their roots rather than seeds.
These plants produce seeds in their flowers, which can grow into new plants if the conditions are favorable.
Some seeds, such as sesame seeds, are used as a culinary ingredient and have various medicinal and cosmetic uses.
