Question

Anastral mitosis can be traced in
A) Invertebrates
B) Vertebrates
C) Both A and B
D) Plant cells

Answer 1

Hint: The mitotic cell division involves the formation of two new cells from the parent cell. This division completes in four phases; prophase, metaphase, anaphase, and telophase.

Complete answer:
To solve this question, we must know about mitosis. Mitosis is a nuclear division of cells. In this process one cell is divided into two daughter cells. This results in the separation of duplicated genetic material found in the nucleus. The mitotic cell division consists of different phases- prophase, metaphase, anaphase and telophase. The mitosis process is of two types- anastral and astral. The anastral mitosis is the mitosis process in which the centroils or esters are not observed during metaphase and in astral mitosis the centriole is observed. The anastral type of mitotic division is mostly found in plants and higher animals. In other words, in anastral metaphase the astral rays and the asters are not produced at the poles of the spindles during the metaphase.

Now lets us find the solution from the given options:
Invertebrates are the animals that do not have backbone, have no cell wall, and multicellular. The invertebrates possess astral mitosis during metaphase. The asters are formed from the centrioles.
Next, vertebrates are animals that have spinal cords made of cartilage; they include the higher animals. They also possess anastral mitosis during metaphase and the asters are formed from the centrioles. Like vertebrates the plant cell also undergoes anastral mitotic division.

Thus, the right answer is option D. i.e., Plant cell

Note: Mitosis is a phenomenon in which the cell divides and forms two identical daughter cells. In this process one cell is divided and helps in the growth of the cells and also wears out the cell. The growth in the height that we observed with age is due to mitosis.
