What is a likely consequence when plants transpire excessive amounts of water?

• A. They may experience wilting due to water loss.
• B. They will absorb more carbon dioxide.
• C. They will increase their rate of photosynthesis.
• D. They will produce more glucose.

Answer: (A)

Verified step by step guidance

1. Understand the process of transpiration: Transpiration is the loss of water vapor from plant leaves through small openings called stomata. It is a normal physiological process that helps in nutrient transport and temperature regulation.
2. Consider the consequences of excessive water loss: When plants lose too much water through transpiration, they may struggle to maintain their internal water balance, leading to dehydration and reduced turgor pressure in cells.
3. Relate excessive water loss to wilting: Wilting occurs when plant cells lose turgor pressure due to insufficient water, causing the plant to droop or collapse. This is a direct consequence of excessive transpiration.
4. Evaluate the other options: Absorbing more carbon dioxide, increasing photosynthesis, or producing more glucose are not direct consequences of excessive water loss. In fact, excessive water loss can hinder these processes because stomata may close to conserve water, reducing gas exchange and photosynthesis.
5. Conclude that wilting is the most likely consequence: Based on the physiological effects of excessive transpiration, wilting due to water loss is the correct answer.
