Question

Which division is characteristic of cartilage cells, mega nucleus of Paramecium and foetal membranes?
A) Mitosis
B) Meiosis
C) Cryptomitosis
D) Amitosis

Answer 1

Hint:In this type of cellular division daughter cells do not have the same number of chromosomes and spindle fibres are not developed during cell division.

Complete answer:
Cell division means that the cell is divided by a parent into two or more daughter cells. The division of cells usually takes place as part of a larger cell cycle. There are 2 different forms of cell division in eukaryotes: the vegetative division that is genetically identical to the parental cell (mitosis) of each daughter and a reproductive division that reduces by half the number of clots in the daughter's gametes. Meiosis results in four haploid daughter cells, followed by two divisions, by one round of replication of DNA. The first division is divided into homologous chromosomes, while the second division is divided into sister chromatids. The two cell division cycles are employed at some point in their life cycle in the process of sexual reproduction.

Amitosis is the cell division process that mainly affects lower organisms such as bacteria. This type of cell division is a primitive type of division in which the cell nucleus unfairly divides and then divides the cytoplasm. This process is called karyokinesis. In amitosis, the chromatin fibres do not condense into chromosomes. The chromosomes are not clearly visible as chromatics and Centromeres. The chromatin fibres are not repeated as in mitosis when the cells are split into amitosis. When the nucleus separates into two nuclei, the genetic material is not distributed equally. Thus the two daughter cells do not appear similar. The cytoplasm is, then separated. The amitosis is characteristic of cartilage cells, mega nucleus of Paramecium and foetal membranes

Thus, the correct answer is option D. i.e., Amitosis.

Note:Human beings can reproduce, grow, and are alive because of a most essential process which takes place in all living beings termed as cellular division. The cells are divided by three types, namely amitosis, meiosis and mitosis, in living organisms.
