   During photosynthesis, plants consume carbon dioxide and release oxygen into the air.

3. How do guard cells function in a leaf?

   1. They absorb sunlight
   2. They protect against insects
   3. They regulate gas exchange
   4. They store nutrients
   Show answer

   Answer: C. They regulate gas exchange

   Guard cells surround stomata and control their opening and closing, regulating gas exchange and water loss.

4. What process explains water movement through a plant, involving loss from leaves?

   1. Photosynthesis
   2. Respiration
   3. Transpiration
   4. Osmosis
   Show answer

   Answer: C. Transpiration

   Transpiration is the process of water movement through a plant and its evaporation from aerial parts.

5. In photosynthesis, light energy is converted into which type of energy?

   1. Mechanical energy
   2. Chemical energy
   3. Thermal energy
   4. Nuclear energy
   Show answer

   Answer: B. Chemical energy
