Which one of the following is not as well-defined in plants as in animals?
Correct answer: B. Organs
- A. Tissues
- B. Organs
- C. Cells
- D. All of these
Explanation
Organs in plants, such as leaves, stems, and roots, are less distinctly defined compared to the highly specialized organs found in animals. In animals, organs are part of complex systems that perform specific functions, whereas in plants, organs are simpler and often perform multiple functions. Tissues and cells are well-defined in both plants and animals, making them incorrect choices.
