Study Notes
Plant Processes
- Respiration: process of releasing energy from glucose
- Photosynthesis: process of converting light energy into chemical energy
Components of Photosynthesis
- Light-dependent reactions: produce ATP and NADPH
- Light-independent reactions (Calvin cycle): produce glucose
- Chlorophyll: absorbs light energy
- Stomata: regulate CO2 and O2 exchange
- Thylakoids: contain pigments, including chlorophyll
Chlorophyll Molecule
- Head: contains magnesium ion, absorbs light energy
- Tail: embedded in thylakoid membrane, anchors chlorophyll
Leaf Parts
- Mesophyll: inner tissue where photosynthesis occurs
- Cuticle: waxy outer layer, prevents water loss
- Epidermis: outer layer, protects leaf from environment
- Veins: xylem and phloem vessels, transport water and nutrients
Leaf Adaptations
- Thick cuticle: reduces water loss in arid environments
- Stomata: regulate CO2 and O2 exchange, conserve water
- Waxy coatings: prevent water loss, reflect light
Chlorophyll-related Features
- Chloroplasts: contain chlorophyll, site of photosynthesis
- Fluorescence: energy released as light, indicates photosynthesis
Transport Vessels
- Xylem: transports water and minerals from roots to leaves
- Phloem: transports sugars, amino acids, and hormones throughout plant
Uses of Glucose in Plant Nutrition
- Energy source: provides energy for plant growth and development
- Building block: used to synthesize other organic molecules
- Stored energy: stored in roots, stems, and leaves for later use
