Study Notes
Plant Classification
- Kingdom Plantae: includes all plants, from tiny microorganisms to giant trees
- Divided into 12 major groups, including:
- Bryophyta (mosses)
- Marchantiophyta (liverworts)
- Anthocerotophyta (hornworts)
- Pteridophyta (ferns)
- Gymnospermae (conifers)
- Angiospermae (flowering plants)
Plant Structure
-
Roots: underground structures that absorb water and nutrients
- Types: taproot, fibrous root, adventitious root
-
Stems: above-ground structures that support leaves and transport materials
- Types: herbaceous, woody, succulent
-
Leaves: organs that carry out photosynthesis
- Types: simple, compound, needle-like, scale-like
-
Flowers: reproductive structures that produce seeds
- Types: complete, incomplete, perfect, imperfect
Plant Functions
- Photosynthesis: process by which plants produce glucose from sunlight, water, and CO2
- Respiration: process by which plants break down glucose to produce energy
- Transpiration: process by which plants release water vapor into the air
- Nutrient uptake: process by which plants absorb nutrients from the soil
Plant Growth and Development
- Seed germination: process by which a seed begins to grow
- Cell growth and division: process by which plants increase in size
- Differentiation: process by which cells become specialized to perform specific functions
- Hormone regulation: process by which hormones control plant growth and development
Plant Responses
- Phototropism: growth response to light
- Geotropism: growth response to gravity
- Thigmotropism: growth response to touch
- Hydrotropism: growth response to water
Plant Ecology
- Terrestrial ecosystems: forests, grasslands, deserts, etc.
- Freshwater ecosystems: rivers, lakes, wetlands, etc.
- Marine ecosystems: coral reefs, kelp forests, estuaries, etc.
- Plant-animal interactions: mutualism, commensalism, parasitism, predation
