Study Notes
Importance of Plants
- Plants provide food for humans and other animals and produce oxygen through converting carbon dioxide into oxygen.
- There are over 80,000 species of edible plants on Earth.
Roots
- Roots are the bottom part of the plant, buried in soil, holding the plant in place, and supporting the stem.
- Roots absorb water and nutrients from the soil for the plant's growth and health.
- There are two types of roots: tap root (main root) and lateral roots (anchoring the plant).
- Roots store food for the plant to use in the future.
- Some edible roots include carrots and beets.
Stem
- The stem is the main part of the plant, supporting the weight of leaves, flowers, or fruit.
- Stems carry water and nutrients from roots to the rest of the plant.
- Stems can be bendable (like flower stems) or woody (like tree stems/trunks).
- Main stems may have smaller stems (branches) growing off of them.
- Some edible stems include asparagus.
Leaves
- Leaves make food for plants through photosynthesis, requiring sunlight, carbon dioxide, and water.
- During photosynthesis, plants produce oxygen as a byproduct.
- Leaves can also be a food source, such as lettuce and spinach.
Flowers or Fruit
- Flowers grow on stems, attracting insects or animals with beauty and smell, and providing nectar in return.
- Flowers facilitate pollination, allowing plants to produce seeds.
- Some flowers turn into fruit, such as apples or oranges, providing food for humans and animals.
- Seeds can travel through wind, water, or animals, allowing plants to reproduce.
