Study Notes
Water
Importance of Water:
- Essential for plant growth and development
- Constitutes about 90% of a plant's tissue
- Necessary for photosynthesis, transportation of nutrients, and temperature regulation
Functions of Water:
- Photosynthesis: Water is the reactant that combines with CO2 to produce glucose and O2
- Transportation of Nutrients: Water helps dissolve and transport nutrients and minerals from soil to plant cells
- Temperature Regulation: Water helps regulate plant temperature through transpiration, evaporative cooling, and heat conduction
- Cell Turgor: Water maintains cell shape and structure, providing mechanical support to the plant
Types of Water Uptake:
- Active Uptake: Plants absorb water through root hairs, using energy from ATP
- Passive Uptake: Plants absorb water through osmosis, using concentration gradients
Water Deficiency:
- Drought: Prolonged water deficiency, leading to reduced growth, wilting, and plant death
- Water Stress: Short-term water deficiency, leading to reduced growth and productivity
Factors Affecting Water Uptake:
- Soil Type: Water availability and uptake affected by soil texture, structure, and moisture content
- Climate: Temperature, humidity, and light affect water uptake and transpiration rates
- Root Depth: Deeper roots can access more water, but may be less efficient in water uptake
