Cell Division Practice Quiz

Mitosis is a process in which a single cell divides into two identical daughter cells. During mitosis, the genetic material of the original cell is replicated and distributed equally between the two daughter cells, ensuring that they are exact copies of the original cell. Therefore, the correct answer is "makes exact copies of the original cell."

The correct answer is "Prophase, Metaphase, Anaphase, Telophase." These are the four phases of mitosis, which is the process of cell division. During prophase, the nuclear membrane dissolves, and the chromosomes condense. In metaphase, the chromosomes align in the middle of the cell. Anaphase is when the sister chromatids separate and move to opposite ends of the cell. Finally, in telophase, the nuclear membrane reforms, and the chromosomes decondense.

Cells use mitosis for repair of damaged tissue, reproduction of cells that die, and growth as an organism matures. Mitosis is a type of cell division where a single cell divides into two identical daughter cells. This process is essential for the growth and development of an organism, as it allows for the replacement of damaged or dead cells and contributes to tissue repair. Therefore, all of the given options are correct explanations for why cells use mitosis.

Mitotic cell division is the process by which somatic cells divide to produce two identical daughter cells. In animals, this type of cell division is only observed in diploid somatic cells, which are the non-reproductive cells of the body. This is because somatic cells contain two sets of chromosomes, one from each parent, and mitosis ensures that each daughter cell receives a complete set of chromosomes. In contrast, reproductive cells undergo meiotic cell division, which results in the formation of haploid cells with half the number of chromosomes. Therefore, the statement that mitotic cell division is only seen in diploid somatic cells in animals is true.

In meiosis, one cell undergoes two rounds of cell division, resulting in the formation of four daughter cells. Each of these daughter cells contains half the number of chromosomes as the parent cell. Therefore, the correct answer is 4, indicating that four cells are produced during meiosis.

Amoeba reproduces through a process called binary fission, where one cell divides into two identical daughter cells. This division is a form of asexual reproduction, as the resulting cells are genetically identical to the parent cell. Therefore, the statement that one-cell division is not equivalent to reproduction in amoeba is false.

During cell division, the process of cytokinesis divides the cytoplasm, organelles, and cell membrane. This ensures that each newly formed daughter cell receives a complete set of cellular components necessary for its functioning. Therefore, the correct answer is "all of the above."

There are three types of cell division: binary fission, mitosis, and meiosis. Binary fission is a form of cell division that occurs in prokaryotic organisms, where the cell divides into two identical daughter cells. Mitosis is a type of cell division in eukaryotic organisms, where a single cell divides into two identical daughter cells. Meiosis is a specialized form of cell division that occurs in eukaryotic organisms, specifically in the formation of gametes (sperm and egg cells), resulting in four non-identical daughter cells.

Walther Flemming is the correct answer because he was a German biologist who made significant contributions to the field of cytology. He discovered cell division and was the first to describe the process of mitosis. Flemming's observations and research on cell division laid the foundation for our understanding of how cells reproduce and divide.

During prophase I of meiosis, synapsis occurs, which is the pairing of homologous chromosomes. This is followed by the formation of tetrads, where each pair of homologous chromosomes aligns closely together. Chiasmata formation then takes place, which is the physical connection between non-sister chromatids of homologous chromosomes. Finally, crossing over occurs, where genetic material is exchanged between the non-sister chromatids of homologous chromosomes. This process increases genetic diversity by creating new combinations of alleles.
