Q: In cell biology, which large double membrane bound organelle is sometimes also known as the central unit of the cell because it contains chromosomes that bear genetic material ?
  • A. Nucleus
  • B. Peroxisome
  • C. Lysosome
  • D. Mitochondria
Correct Answer: Option A - Nucleus is a large double - membrane bound organelle, also known as the 'central unit' of the cell because it contains chromosomes that bear genetic material. Nuclear membrane is a double-membrane barrier that encloses the nucleus, separating it from the cytoplasm. The nucleus contains the cell's hereditary material (DNA), which dictates everything from cell structure to function.
