Explain how rainwater helps a tree grow, mentioning at least two ways.
Answer
Rainwater supplies water and dissolved minerals, enabling roots to absorb nutrients and the tree to perform photosynthesis and transpiration.
Step-by-step solution
- Rainwater brings water that tree roots absorb for growth.
- The water dissolves minerals from soil, delivering nutrients like potassium and calcium to the tree.
- With sufficient water, the tree can carry out photosynthesis, converting light into energy.
- Water also helps in transpiration, maintaining plant turgor and moving nutrients.
- Thus, rainwater supports both hydration and nutrient supply for tree growth.
Common mistake: Mentioning only water without nutrients or plant processes
Concept tested: Rainwater benefits for plants
