When a eukaryotic cell undergoes cellular division, creating two new daughter cells that have the same number of chromosomes as the parent cell, the cell has undergone
a
meiosis.
b
endocytosis.
c
mitosis.
d
binary fission.
c
mitosis.
The correct answer is c) mitosis.
Mitosis is a type of cellular division in eukaryotic cells where the cell's nucleus divides, resulting in the formation of two daughter cells. During mitosis, the chromosomes in the parent cell are replicated, and each daughter cell receives an identical set of chromosomes as the parent cell. This process allows for growth, development, and tissue repair in multicellular organisms.
The correct answer is c) mitosis.
Mitosis is the process of cell division in which a single eukaryotic cell divides into two identical daughter cells. During mitosis, the cell's chromosomes, which contain its genetic information, are duplicated and separated into two nuclei. This ensures that each daughter cell receives an exact copy of the parent cell's DNA.
To understand why mitosis is the correct answer to the question, let's briefly discuss the other options:
a) Meiosis: Meiosis is a type of cell division that occurs in sexually reproducing organisms to produce gametes (e.g., eggs and sperm). It results in the formation of cells with half the number of chromosomes as the parent cell. Thus, meiosis leads to genetic diversity rather than preserving the same number of chromosomes.
b) Endocytosis: Endocytosis is a cellular process by which substances are brought into the cell. It has no involvement in cell division.
d) Binary fission: Binary fission is a type of cell division that occurs in prokaryotes (organisms without a nucleus, such as bacteria). During binary fission, the single circular chromosome replicates, and the cell splits into two genetically identical cells. However, since the question specifically mentions a eukaryotic cell, binary fission is not the correct answer.
Therefore, the correct answer is c) mitosis.
