Which of the following structure is present in both plant and animal cells but is absent in prokaryotic cells?
Correct answer: B. Microtubule
- A. Centrioles
- B. Microtubule
- C. Plastids
- D. Sieve tubes
Explanation
Mitotic and meiotic cell divisions are absent in bacterial cells instead bacterial cells divide through binary fission. Microtubules are responsible for spindle formation and these ensure mitosis and meiosis in eukaryotic cells.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
