Study Notes
Meristematic Tissue
- Primary function: Growth and development of plants
- Apical meristem: Responsible for the increase in length of stems and roots
- Dedifferentiation: The process allowing a differentiated cell to revert to a meristematic state
Plant Tissues
- Simple permanent tissue: Consists of only one kind of cell
- Guard cells: Responsible for controlling gas exchange in plants
- Parenchyma tissue: Involved in storage, photosynthesis, and secretion
- Cutin: Waxy substance that protects plant tissues from water loss
Plant Growth and Structure
- Lateral meristem: Not typically found in monocot plants
- Collenchyma tissue: Provides flexible support; unevenly thickened walls
- Sclerenchyma tissue: Provides structural support and strength
- Vessel elements: Wider and more efficient in transporting water than tracheids
- Sieve tube elements: Act as a sieve plate in phloem, facilitating nutrient flow
- Taproot system: Characterized by a main primary root with lateral branches
- Radicle: The embryonic root in a germinating seed
- Translocate: Term describing the movement of substances through the xylem and phloem

- Positive gravitropism: Growth response in which a part of the plant grows downwards
- Abscisic acid: A stress hormone that inhibits growth
- Gibberellins: Stimulate stem elongation and seed germination
Plant Growth and Reproduction
- Short-day plant: Requires a short period of light each day to flower
- Phototropism: Stem growth in response to light
- Cytokinin: Used in plant tissue cultures for the production of shoot buds
