What side effect of photosynthesis is closely related to transpiration?

In the process of photosynthesis, plants take in carbon dioxide and water to produce glucose and oxygen. While this is primarily about the conversion of light energy into chemical energy, transpiration plays a key role in water loss from the plant.

Transpiration is the process through which water is absorbed by plant roots from the soil, moves through the plant, and evaporates from small pores called stomata on the leaves' surface. When plants photosynthesize, stomata open to allow carbon dioxide in for the production of glucose. However, opening the stomata also allows water vapor to escape, leading to water loss.

The loss of water through transpiration is linked to photosynthesis because it creates a negative pressure that helps pull more water up from the roots, supporting both processes. Thus, the loss of water as a side effect of photosynthesis is closely related, illustrating the interconnected nature of these physiological processes in plants.
