Study Notes
Characteristics of Plants
- Autotrophic organisms: produce their own food through photosynthesis
- Multicellular: composed of multiple cells
- Eukaryotic: cells have a true nucleus
- Non-motile: stationary organisms
Plant Structure
- Roots: underground structures that absorb water and nutrients
- Stems: above-ground structures that support leaves and transport materials
- Leaves: organs responsible for photosynthesis
- Flowers: reproductive structures that produce seeds and fruits
Photosynthesis
- Process by which plants convert light energy into chemical energy
- Requires:
- Light
- Water (H2O)
- Carbon dioxide (CO2)
- Chlorophyll (green pigment)
- Produces:
- Glucose (energy source)
- Oxygen (byproduct)
Types of Plants
- Flowering plants (Angiosperms): produce flowers and seeds
- Conifers (Gymnosperms): produce cones and seeds
- Ferns (Pteridophytes): produce spores
- Mosses (Bryophytes): non-vascular, produce spores
- Algae (Chlorophytes): simple, aquatic plants
Plant Functions
- Support: provide structural support for other organisms
- Food: produce food for humans and other organisms
- Oxygen: produce oxygen through photosynthesis
- Shelter: provide habitats for other organisms
- Medicine: source of medicinal compounds
Characteristics of Plants

- Non-motile, stationary organisms
Plant Structure
- Roots absorb water and nutrients underground
- Stems support leaves and transport materials above-ground
- Leaves are responsible for photosynthesis
- Flowers are reproductive structures that produce seeds and fruits
Photosynthesis
- Converts light energy into chemical energy
- Requires light, water, carbon dioxide, and chlorophyll
- Produces glucose as an energy source and oxygen as a byproduct
Types of Plants

Characteristics of Plants
- Plants are multicellular, eukaryotic organisms that produce their own food through photosynthesis and are non-motile (stationary)
Plant Structure
- Roots are underground structures that absorb water and nutrients
- Stems are above-ground structures that support leaves and transport nutrients
- Leaves are organs of photosynthesis responsible for gas exchange
- Flowers are reproductive structures that produce seeds
Photosynthesis
- Is the process by which plants convert light energy into chemical energy
- Requires light, water (H2O), and carbon dioxide (CO2)
- Produces glucose (energy source) and oxygen (O2)
Types of Plants
- Bryophytes are non-vascular plants (e.g., mosses, liverworts)
- Pteridophytes are vascular plants that reproduce via spores (e.g., ferns)
- Gymnosperms are vascular plants with seeds, but no flowers (e.g., conifers)
- Angiosperms are flowering plants with seeds (e.g., fruits, vegetables)
Importance of Plants
- Provide oxygen and food for humans and animals
- Support ecosystems and biodiversity
- Help regulate the climate and water cycles
- Are used in medicine, construction, and other industries
