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.
