Study Notes
Plant Classification
- Monocots: Angiosperms characterized by a single seed leaf.
- Dicots: Angiosperms that develop two seed leaves.
Plant Structures and Functions
- Stomata: Microscopic openings on leaf undersides facilitating gas exchange; crucial for oxygen and carbon dioxide movement.
- Xylem: Vascular tissue responsible for upward water transport from roots to all plant parts.
- Phloem: Living vascular tissue that transports sugars and organic substances throughout the plant.
- Vascular Tissue: Composed of tubular cells that move water and nutrients, essential for plant health.
Plant Properties and Processes
- Water Potential: Determines water movement direction based on solute concentration and pressure; key in plant hydration and nutrient uptake.
Types of Seed Plants
- Angiosperms: Flowering plants with seeds enclosed in an ovary; essential for fruit and seed development.
- Gymnosperms: Seed-producing plants with exposed seeds, not enclosed in fruits.
Growth Regulators
- Gibberellins: Hormones that promote stem and leaf growth, seed germination, bud dormancy breaking, and fruit development.
Plant Organs
- Roots: Anchor plants and absorb water and minerals; foundational for plant stability and growth.
- Leaves: Main sites for photosynthesis and transpiration; critical for energy production.
- Stems: Structural support connecting roots and leaves, facilitating water and nutrient transportation.
- Rhizomes: Horizontal underground stems that serve as storage and propagation organs.
Reproductive Structures
- Frond: Refers to a fern leaf or leaves of palms and bananas.
- Cone: Gymnosperm reproductive structure; crucial for seed production.
- Flower: The reproductive structure of angiosperms; central to sexual reproduction in these plants.
- Pollen Grain: Male gametophyte in seed plants; essential for fertilization.
- Pollination: Process of transferring pollen from male to female structures; vital for seed production.
- Seed: A protective package consisting of an embryo, nutrient store, and coat; essential for reproduction in terrestrial plants.
