Study Notes

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 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.

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 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 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.
