What is the term for the loss of water from the stroma of a plant?

• A. Photosynthesis
• B. Transpiration
• C. Osmosis
• D. Evaporation

Answer: (B)

The process that refers to the loss of water from the stroma of a plant is called transpiration. This occurs primarily through small openings known as stomata, which allow water vapor to escape into the atmosphere. Transpiration is a vital aspect of a plant's lifecycle as it helps in the uptake of nutrients and regulates temperature. The water vapor released contributes to the plant's overall water cycle, promoting the movement of water from the roots through the plant and eventually into the air. In contrast, photosynthesis is the process by which plants convert light energy into chemical energy, primarily through the chloroplasts, and is not specifically focused on water loss. Osmosis refers to the movement of water across a semipermeable membrane and does not directly describe water loss from the stroma. Lastly, evaporation is a general term that involves the transition of liquid water to vapor, but it does not specifically pertain to the biological processes occurring in plants as transpiration does.
