A leaf with a higher density of stomata can take up more CO 2 and release more water than a leaf with a lower density of stomata.
-Consider two plant types: 1. Plants that grow in arid (dry) environments
2) Plants that grow in moist (e.g., wetland) environments
Which plant would you expect to have fewer stomata, and why?

Plants in arid environments (the first type) face water scarcity, so they need to conserve as much water as possible. Therefore, they would have fewer stomata to minimize water loss through transpiration. On the other hand, plants in moist environments (the second type) have abundant water, so they can afford to release more water through transpiration, helping with cooling and nutrient uptake. Therefore, they would have a higher density of stomata to increase their gas exchange and photosynthetic activity.
