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.
