Answer: (D)

Verified step by step guidance

1. Understand the concept of cellular respiration: Cellular respiration is a metabolic process where cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water. This process occurs in the mitochondria of eukaryotic cells.
2. Recognize that cellular respiration is essential for energy production: All eukaryotic organisms, including plants, animals, fungi, and protists, rely on cellular respiration to generate ATP for cellular activities.
3. Clarify the role of plants: Plants perform both photosynthesis and cellular respiration. During photosynthesis, they produce glucose and oxygen, which are then used in cellular respiration to generate ATP.
4. Clarify the role of animals: Animals rely on cellular respiration to convert glucose (obtained from food) and oxygen into ATP, which powers their cellular functions.
5. Conclude that both plants and animals undergo cellular respiration: Cellular respiration is not exclusive to any single group of organisms; it is a universal process among eukaryotes, including both plants and animals.
