give one disadvantage of having a large number of stomata per mm squared of leaf surface
Answer:
The downside to wide open stomata is increased water loss (transpiration). So stomata of cool-season turfgrasses have decisions to make. The plant needs to capture and store energy via photosynthesis, however, excessive water loss through transpiration can result in plant injury or death.
One disadvantage of having a large number of stomata per mm squared of leaf surface might be the excessive loss of water.
What are stomata?Stomata are specialized plant structures used to exchange gases such as oxygen and carbon dioxide.
The plant structures (stomata) are especially located on the leaves where photosynthesis mainly occurs.
In conclusion, one disadvantage of having a large number of stomata per mm squared of leaf surface might be the excessive loss of water.

why is anaerobic respiration useful?
Answer:
It is useful during exercise. When the body doesn't get enough oxygen during exercise, it relies on anaerobic respiration for an energy supply. Instead of carbon dioxide and water, however, anaerobic respiration produces lactic acid. Also, anaerobic respiration releases less energy than aerobic respiration but it does this more quickly.
