Chromosomes in the nuclei of onion cells are clearly distinguishable under a light microscope

Chromosomes in the nuclei of onion cells are clearly distinguishable under a light microscope a) only during division b) at a certain stage of growth c) always d) throughout the entire growth process.

Chromosomes are stored in the nucleus of cells. They play a direct role in the process of protein synthesis and cell reproduction. But seeing the chromosomes is quite difficult. They are small in size, and it is difficult to see them in a light microscope. But during cell division, this is much easier to do. The fact is that when the cell is being prepared for division, the number of chromosomes in the nucleus doubles. To view and study them as structures, scientists use electron microscopes, which are more powerful than light microscopes.
