Which shows cell reproduction seen in bacteria?
a
Binary fission
b
Mitosis
c
Meiosis
d
Bacteria use all three methods for cell division.
The correct answer is a) Binary fission. Binary fission is the process of cell reproduction that is observed in bacteria. In this process, a single cell divides into two identical daughter cells. This is the primary method of cell reproduction for bacteria. Option b) Mitosis is a process seen in eukaryotic cells, where a single cell divides into two identical daughter cells. Option c) Meiosis is a specialized form of cell division seen in eukaryotic cells that produces gametes or reproductive cells. Option d) is incorrect as it states that bacteria use all three methods of cell division, which is not true.
The model of cellular reproduction shown in the image is the process of binary fission.
To determine which model of cellular reproduction is seen in bacteria, let's review the three options given:
a) Binary fission: This is the process of cell division commonly observed in bacteria. In binary fission, the bacterial cell simply divides into two nearly equal-sized daughter cells.
b) Mitosis: Mitosis is a type of cell division found in eukaryotic cells, including those of plants, animals, and fungi. It involves the division of a parent cell into two identical daughter cells.
c) Meiosis: Meiosis is also a type of cell division found in eukaryotic cells but specifically involved in the production of gametes (sperm and egg cells). Meiosis generates four non-identical daughter cells, each with half the number of chromosomes as the parent cell.
d) Bacteria use all three methods for cell division: This option suggests that bacteria employ all three models of cell division (binary fission, mitosis, and meiosis).
Based on the description provided, it is clear that option a) Binary fission is the correct answer. Bacteria typically reproduce through binary fission, where one cell divides into two separate cells.
