What gas leaves the stoma as a product of photosynthesis? __ Add to your foldable. gas leaving and another entering is called gas __ is the loss of water through the stoma in the leaves called? __ would a plant need to lose water? __

## Step 1<br />The first question asks about the function of the leaf. The leaf is the primary site of photosynthesis in a plant, where light energy is converted into chemical energy.<br /><br />## Step 2<br />The second question asks about the purpose of the guard cells closing the stomata. The guard cells close the stomata to prevent excessive water loss from the plant, which is a process known as transpiration.<br /><br />## Step 3<br />The third question asks about the gas that must enter the stomata for photosynthesis to occur. The gas that must enter the stomata for photosynthesis to occur is carbon dioxide (CO2).<br /><br />## Step 4<br />The fourth question asks about the gas that leaves the stoma as a product of photosynthesis. The gas that leaves the stoma as a product of photosynthesis is oxygen (O2).<br /><br />## Step 5<br />The fifth question asks about the term for the loss of water through the stoma in the leaves. The loss of water through the stoma in the leaves is called transpiration.<br /><br />## Step 6<br />The sixth question asks about why a plant would need to lose water. A plant would need to lose water to cool itself down, to maintain the water potential gradient necessary for nutrient uptake, and to facilitate the diffusion of gases in and out of the leaf.
