Which statement describes an incorrect difference between a plant cell and a bacterial cell?

Correct answer: D. None of these options are correct

  • A. Bacterial cell has 70S ribosomes whereas a plant cell has 80S ribosomes
  • B. Bacterial cell divides by binary fission whereas a plant cell divides by mitosis
  • C. Bacterial cells do not have a nuclear membrane whereas plant cells do
  • D. None of these options are correct

Explanation

The statement "Bacterial cell has 70S ribosomes whereas a plant cell has 80S ribosomes" is true. Bacterial cells typically have 70S ribosomes, which are smaller and less complex than the 80S ribosomes found in eukaryotic cells like plant cells. The statement "Bacterial cell divides by binary fission whereas a plant cell divides by mitosis" is also true. Bacterial cells reproduce through binary fission, a process where the cell divides into two identical daughter cells. On the other hand, plant cells and other eukaryotic cells divide through mitosis, a more complex process involving the division and distribution of genetic material into two daughter cells. The statement "Bacterial cells do not have a nuclear membrane whereas plant cells do" is true as well. Bacterial cells are prokaryotic, meaning they lack a true nucleus and other membrane-bound organelles. Plant cells, being eukaryotic, do have a distinct nucleus enclosed within a nuclear membrane. So, none of the given statements describes an incorrect difference between a plant cell and a bacterial cell.
