### Scientific Explanation of a Seed:
A **seed** is a reproductive structure produced by certain plants, particularly angiosperms (flowering plants) and gymnosperms (non-flowering plants such as conifers). It consists of three main components:
1. **Seed Coat**: This is the outer protective layer of the seed that provides physical protection to the embryo and stored nutrients. It helps prevent damage from physical factors, pathogens, and desiccation.
2. **Embryo**: The embryo is the developing plant itself. It has the potential to grow into a new plant when conditions are favorable. The embryo consists of:
- **Cotyledons** (seed leaves): These may store energy and provide nutrition to the developing seedling.
- **Hypocotyl**: The part of the embryo that will develop into the stem of the plant.
- **Radicle**: The embryonic root that will grow downward as the seed germinates.
3. **Endosperm**: This is a storage tissue that provides nutrients to the developing embryo. It can contain starches, oils, and proteins and is formed during fertilization.
**Function of Seeds**: Seeds serve multiple functions:
- **Reproduction**: They facilitate the reproduction of plants by enabling the formation of new individual plants.
- **Dispersal**: Seeds can be dispersed over long distances, allowing plants to colonize new areas.
- **Dormancy**: Seeds can remain dormant for extended periods until conditions are favorable for germination (sufficient water, temperature, etc.).
### Function of Stomata in Plants:
**Stomata** (singular: stoma) are small openings found on the surface of leaves and stems of plants. They are primarily involved in gas exchange and have the following functions:
1. **Gas Exchange**: Stomata allow the exchange of gases between the plant and the atmosphere. They enable the entry of carbon dioxide (CO2) necessary for photosynthesis and the release of oxygen (O2) as a byproduct.
2. **Transpiration**: Stomata play a critical role in the process of transpiration, where water vapor is lost from the plant to the atmosphere. This process helps in:
- Cooling the plant.
- Creating a negative pressure that helps draw water and nutrients from the roots up through the plant.
3. **Regulation**: Guard cells surround each stoma and control its opening and closing. The opening of stomata can be adjusted based on environmental conditions (e.g., humidity, light intensity) and the plant's water status. This regulation helps maintain optimal water balance and gas exchange, contributing to plant health and productivity.
In summary, seeds are integral to plant reproduction and survival, while stomata are essential for gas exchange and maintaining water balance in plants.
