Which of the following pair is correct? I. Prokaryotic Cell - One chromosome II. Eukaryotic Cells - More than one chromosome

Which of the following pair is correct? I. Prokaryotic Cell - One chromosome II. Eukaryotic Cells - More than one chromosome Correct Answer Both I and II

The correct answer is Both I and II.

Key Points

  • Prokaryotic cells:
    • Organisms that lack a membrane-bound nucleus are called prokaryotes.
    • A prokaryotic cell does not contain a well-defined nucleus.
    • The genetic material is present on a single chromosome.
    • All prokaryotes have a cell wall surrounding the cell membrane except in mycoplasma.
    • The nucleolus is absent in prokaryotic cells.
    • The fluid matrix filling the prokaryotic cell is the cytoplasm.
    • Membrane-bound cell organelles are absent in prokaryotes.
    • In prokaryotes, cell division takes place by fission or budding.
    • Blue-green algae, bacteria, and mycoplasma are examples of prokaryotes.
  • Eukaryotic Cells:
    • Eukaryotic cells have a nucleus enclosed within the nuclear membrane and form large and complex organisms.
    • They can maintain different environments in a single cell that allows them to carry out various metabolic reactions.
    • This helps them grow many times larger than the prokaryotic cells. 
    • Since eukaryotic cells typically have multiple linear chromosomes, capped with telomeres, eukaryotic DNA replication and cell division (mitosis and meiosis) are a bit more complicated.
    • Protozoa, fungi, plants, and animals all have eukaryotic cells.
