Question

binary fission: simple cell division
have you ever wondered how tiny organisms like bacteria multiply so quickly? the answer is a process called binary fission. this is a type of asexual reproduction, meaning only one parent is needed to produce offspring. it is most common in prokaryotic cells, such as bacteria, which lack a true nucleus. in simple terms, binary fission is the process where one cell divides into two identical new cells.
the process of binary fission is a carefully organized sequence of events. first, the single circular chromosome, which contains the cells dna (deoxyribonucleic acid), replicates, making an exact copy of itself. the two identical copies of the dna then move to opposite ends of the parent cell. as the cell grows longer, the cell membrane and cell wall begin to pinch inward in the middle. finally, a new wall called a septum forms, completely separating the cytoplasm and dividing the original parent cell into two new, smaller daughter cells.
the result of binary fission is two daughter cells that are genetically identical to each other and to the original parent cell. this means they have the exact same dna. this process allows populations of single - celled organisms to grow very rapidly. for example, the bacterium e. coli, which can be found in the human gut, can divide every 20 minutes under ideal conditions. other examples of organisms that use binary fission to reproduce include amoeba and paramecium. this efficient method of reproduction is why bacteria can colonize a new environment so quickly. the process of meiosis: creating genetic diversity
one - word answers

1. binary fission is a type of ______ reproduction.
2. the process of binary fission occurs most commonly in ______ cells.
3. the genetic material of a bacterial cell is in the form of a single ______ chromosome.
4. the new wall that forms between two dividing cells is called a ______.
5. the two new cells produced are called ______ cells.

true or false

1. binary fission requires two parent cells.
2. the daughter cells produced in binary fission are genetically identical.
3. binary fission occurs only in multicellular organisms.
4. e. coli can divide every 20 minutes under ideal conditions.

Explanation:

1. The text states "This is a type of asexual reproduction".
2. It mentions "It is most common in prokaryotic cells".
3. "First, the single circular chromosome, which contains the cell's DNA" indicates the form of genetic - material.
4. "Finally, a new wall called a septum forms".
5. "dividing the original parent cell into two new, smaller daughter cells".

For True - or - False:

1. Binary fission is asexual, so it requires only one parent cell.
2. "The result of binary fission is two daughter cells that are genetically identical".
3. Binary fission is common in single - celled organisms like bacteria, not multicellular ones.
4. "For example, the bacterium E. coli, which can be found in the human gut, can divide every 20 minutes under ideal conditions".
