 | Nidhi Bhatt answered |
Osmosis is the movement of water molecules across a semi-permeable membrane from a region of higher water concentration to a region of lower water concentration. This process is vital for maintaining cell turgidity and nutrient balance.
What can slow down the rate of transpiration?- a)High wind speeds
- b)High humidity
- c)Low humidity
- d)Increased sunlight

d)
Increased sunlight
 | C K Academy answered |
High humidity slows down transpiration because the air is already saturated with moisture, making it difficult for additional water vapor to escape from the plant's stomata. This can impact the plant's ability to cool itself and transport nutrients effectively.
