Study Notes
Plant Reproduction
- Plants differ from animals in that they cannot move.
- Plants have chlorophyll to make food.
- Plant parts like roots, stems, and leaves have specific functions.
Plant Structure
- Roots:
- Roots anchor plants to the ground.
- Roots absorb water and dissolved nutrients from the soil.
- Taproot system: Has a large primary root with secondary and tertiary roots, reaching deeper water sources.
- Fibrous root system: Has many small roots spreading near the surface, absorbing water readily.
- Inside the roots are tube-like structures (bundles)
- Xylem tissue: Transports water and dissolved minerals.
- Phloem tissue: Transports sugar from leaves to other plant parts.
- Stems:
- Support the plant.
- Leaves:
- Produce food for the plant.
