Question

Which statement best explains what happens to a leaf when it has lost much-needed water?

A. Its atmospheric pressure decreases.

B. Its rate of photosynthesis increases.

C. Its rate of transpiration increases.

D. Its turgor pressure decreases.

Answer 1

The answer is C . Transpiration is the evaporation of water from the surface of leaf cells in actively growing plants .. Stomata are quick to respond to environmental cues to protect the plant from losing too much water, but still slowing in enough carbon dioxide to drive photosynthesis. So I’m pretty sure it C

Answer 2

When a leaf loses much-needed water, its turgor pressure would decrease.

Turgor pressure is created in the cells of a leaf when there is enough water. The water stretches the cell membrane outward, creating a kind of pressure.

When the cells lose water, the cell membrane shrinks inward and loses the supporting pressure.

Thus, the turgor pressure created by the presence of water is lost by the absence of water.

The absence of water also affects the rate of photosynthesis and transpiration negatively and not positively. A leaf losing water has no bearing on the atmospheric pressure.
