O two stages.
O four stages.
O one stage.
The process by which a modified stem or root of a parent plant grows offspring that remain attached is called
O tuber reproduction.
O binary fission.
O fragmentation.
O vegetative reproduction.
In bacteria, binary fission can be modeled in two stages:
1. Growth Stage: In this stage, the bacterium grows in size and replicates its DNA.
2. Division Stage: The bacterium divides into two daughter cells, each containing a copy of the replicated DNA. This division is achieved by the formation of a septum (a partition) that separates the cytoplasm of the two daughter cells. Eventually, the septum fully forms, and the two daughter cells separate from each other, giving rise to two genetically identical bacterial cells.
Therefore, the correct answer is:
O two stages.
To determine the answer to this question, we need to understand how binary fission works in bacteria. Binary fission is a form of asexual reproduction in which a single bacterial cell divides into two identical daughter cells.
During binary fission, the following stages occur:
1. Replication: The bacterial cell undergoes DNA replication, resulting in the formation of two identical copies of the bacterial chromosome.
2. Elongation: The cell elongates as the copies of the chromosome move away from each other to opposite ends of the cell.
3. Septum Formation: A new cell wall and cell membrane are synthesized at the midpoint of the cell, leading to the formation of a partition called the septum.
4. Division: The cell is divided into two daughter cells, each containing a copy of the bacterial chromosome.
Based on these stages, it can be concluded that binary fission in bacteria can be modeled in four stages.
Therefore, the correct answer is "four stages."
