When we say that transpiration is equal to water use in plants, we are primarily referring to the process where water is absorbed by the roots, transported to the leaves, and then evaporated into the atmosphere. However, this view oversimplifies the complex water dynamics within a plant and overlooks several other avenues of water use.

1. Aerobic Respiration: This is a process where plants break down sugar molecules to produce energy, carbon dioxide, and water. This water is a byproduct of the respiration process and contributes to the total water use of the plant.

2. Photosynthesis: During photosynthesis, plants use sunlight, carbon dioxide, and water to produce glucose and oxygen. The water used in this process is not accounted for when equating transpiration to total water use.

3. Water Uptake by Non-Photosynthesising Cells: Not all cells in a plant are involved in photosynthesis. Non-photosynthesising cells, such as those in roots, stems, and older leaves, also absorb and use water for various cellular activities. This water usage is not considered in the transpiration equals water use equation.

Therefore, while transpiration is a significant component of a plant's water use, it does not account for all avenues of water use within the plant.
