Which of the following is part of mitosis in cells of seed plants?
Correct answer: C. Spindles
- A. Centrioles
- B. Asters
- C. Spindles
- D. Cleavage furrows
Explanation
Centrioles are not present in plant cells. Mitotic spindles are microtubule based structures that separate chromosomes during mitosis. Asters are radial microtubule arrays found in animal cells. These star-shaped structures form around each pair of centrioles during mitosis. Asters help to manipulate chromosomes during cell division to ensure that each daughter cell has the appropriate complement of chromosomes. The cleavage furrow is the indentation of the cell's surface that begins the progression of cleavage, by which animal and some algal cells undergo cytokinesis, the final splitting of the membrane, in the process of cell division. In plant cells, a cleavage furrow is not possible because of the rigid cell walls surrounding the plasma membrane. The correct answer is, therefore, C.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
