Study Notes
Characteristics of Plants
- Multicellular organisms
- Eukaryotic cells
- Autotrophic, meaning they produce their own food through photosynthesis
- Have cell walls made of cellulose
Types of Plants
- Flowering Plants (Angiosperms): produce flowers and seeds, examples include roses and daisies
- Conifers (Gymnosperms): produce cones and seeds, examples include pines and spruces
- Ferns (Pteridophytes): produce spores, examples include ferns and horsetails
- Mosses (Bryophytes): non-vascular, produce spores, examples include mosses and liverworts
Plant Structure
- Roots: underground structures that absorb water and nutrients
- Stems: above-ground structures that support leaves and transport materials
- Leaves: organs that carry out photosynthesis
- Chloroplasts: organelles found in plant cells that contain chlorophyll and facilitate photosynthesis
Plant Functions
- Photosynthesis: process by which plants convert light energy into chemical energy
- Transpiration: process by which plants release water vapor into the air
- Respiration: process by which plants break down glucose to release energy
Plant Growth and Development
- Seed Germination: process by which a seed begins to grow
- Cell Division: process by which plant cells divide and grow
- Hormone Regulation: plant hormones, such as auxins and gibberellins, regulate growth and development
Plant Responses to Environment
- Tropisms: plant growth responses to environmental stimuli, such as light and gravity
- Nastic Movements: plant movements in response to touch or other stimuli
