Study Notes
Parts of Plants
- Plants have two main parts: root (underground) and shoot (above ground)
Roots
- Remain under the ground
- Have tiny thin hair-like branches that fix the plant firmly in the soil
- Types of roots:
- Fibrous roots: multiple roots growing from the end of the stem (e.g., grass, onion, wheat, rice)
- Tap roots: a long main root with small side roots (e.g., bean, balsam, mustard)
- Functions of roots:
- Fix the plant to the soil
- Provide water and mineral salts to the plants
- Store food in some plants (e.g., carrot, radish, turnip, beet)
Stem
- Main part of the shoot
- Holds the plant upright above the ground
- Bears branches, leaves, buds, flowers, and fruits
- Functions of the stem:
- Holds the plant upright
- Bears leaves, buds, flowers, and fruits
- Carries water and mineral salts from the roots to all parts of the plant
- Carries food prepared by the leaves to different parts of the plant
- Stores extra food in some cases (e.g., sugarcane, potato, ginger)
Leaf
- An important part of the shoot
- Different plants have leaves of different shapes and sizes
- Leaf structure:
- Flat and broad part called leaf blade
- Main vein in the middle with side veins that bring water to the leaf
- Tiny holes on the surface called stomata that throw out extra water
- Plants breathe in and out through stomata
