Plants and animals share the process of cellular respiration in common.
- Cellular respiration is the process by which both plants and animals convert glucose and oxygen into energy, carbon dioxide, and water.
- Transpiration is specific to plants, as it refers to the process of water vapor loss from plant leaves.
- Photosynthesis is unique to plants and some other organisms, where they convert sunlight, carbon dioxide, and water into glucose and oxygen.
- Absorption of water primarily refers to how plants take in water from the soil, although animals do absorb water, it’s not a process they share in the same context as plants do.
So, the correct answer is cellular respiration.
