Question

During Binary fission in Amoeba which of the following organelles is duplicated?
(a)Plasma membrane
(b)Nucleus
(c)Centriole
(d)All of the above

Answer 1

Hint: Binary fission may be a sort of agamogenesis during which the adult parent cell splits into two halves, producing two new daughter cells. it's common among organisms like Bacteria, Amoeba and Paramecium.

Complete answer:
During binary fission, the parent cell divides to supply two equal cells that produce 2 new individuals, e.g., bacteria and amoeba.
Hence in the amoeba nucleus is the parent cell which is duplicated.

Additional Information: Binary Fission in amoeba: Most single-celled organisms use the tactic of binary fission for cellular division and reproduction. These include paramoecium, bacterium, and eventually amoeba. It is a method of reproduction. In binary fission, the amoeba consists of 1 parent which forms the two daughter cells. First, the amoeba cell undergoes a nuclear division in which the nucleus replicates into two. The 2 nuclei divide and move to opposite directions within the parent cell. The cell then starts to produce proteins and nutrients for the preparation for binary fission. within the stage of binary fission, the cell divides and forms 2 daughter cells. This process generally occurs when environmental conditions are most favourable. That's when there's enough food, water, and positive temperature.

So, the correct answer is, “Amoeba”

Note: -Binary fission involves mitosis and the resultant offspring are genetically identical to the parent and each other.
-Similarities:
During binary fission also as mitosis, chromosomes are copied before a cell divides and forms two new daughter cells.
-Differences:
Mitosis may be a process of cellular division, observed altogether by eukaryotes -organisms with a real nucleus.
-Binary fission may be a process of agamogenesis administered by all prokaryotes- organisms without a real nucleus.
