## Step 1<br />The first question asks about the function of the leaf. The leaf is the primary site of photosynthesis in most plants. Photosynthesis is the process by which plants convert light energy, usually from the sun, into chemical energy in the form of glucose or other sugars. These sugars are then used by the plant for growth and other metabolic processes.<br /><br />## Step 2<br />The second question asks about the purpose of the guard cells closing the stomata. The stomata are small openings on the surface of leaves that allow for gas exchange. Guard cells are specialized cells that surround each stoma. They can change shape to open or close the stoma. When the guard cells close the stomata, it helps to reduce water loss from the plant, especially under conditions of drought or high temperatures.<br /><br />## Step 3<br />The third question asks about the gas that must enter the stomata for photosynthesis to occur. For photosynthesis to occur, carbon dioxide (CO₂) must enter the stomata. CO₂ is one of the primary reactants in the photosynthesis process, where it is converted into glucose and oxygen.<br /><br />## Step 4<br />The fourth question asks about the gas that leaves the stoma as a product of photosynthesis. Oxygen (O₂) is the gas that leaves the stoma as a product of photosynthesis. It is produced when carbon dioxide is converted into glucose.<br /><br />## Step 5<br />The fifth question asks about the term for one gas leaving and another entering. This process is called gas exchange. In the context of photosynthesis, gas exchange refers to the movement of carbon dioxide into the leaf and oxygen out of the leaf.<br /><br />## Step 6<br />The sixth 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. It is a process where water vapor is lost from the plant to the atmosphere.<br /><br />## Step 7<br />The seventh question asks about why a plant would need to lose water. Plants lose water through transpiration to help cool themselves. When water evaporates from the surface of the leaves, it helps to lower the temperature of the leaf. Additionally, the loss of water helps to maintain the plant's turgor pressure, which is the pressure of the cell contents against the cell wall. This pressure is essential for maintaining the plant's structure and rigidity.
