During cell division thread like material is converted into darkly stained structures known as:
Correct answer: D. Chromosomes
- A. Nucleoli
- B. Nuclear membrane
- C. Nucleosomes
- D. Chromosomes
Explanation
Nucleus of a non-dividing cell contain chromatin material in form of network which have been obtained by uncoiling and decondensation of chromosomes. As the cell division startsthe chromatin material is recoiled/recondensed to acquire the shape of chromosomes. Chromosomes appear as thread like structures in nucleus at that time under microscope.

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.
