Mitosis & Meiosis
Cell division follows specific phases that ensure genetic material is properly distributed. In prophase, DNA coils tightly into visible chromosomes while the nuclear membrane begins to break down. During metaphase, chromosomes align across the middle of the cell, preparing for separation.
Anaphase begins when chromosomes pull apart toward opposite ends of the cell. Finally, in telophase, the cell completes division as two separate daughter cells form, each with a new nuclear membrane surrounding its genetic material.
Mitosis creates two identical daughter cells from one parent cell, maintaining the same number of chromosomes. This process occurs in most body cells and allows for growth and tissue repair. Diploid cells (with two sets of chromosomes) undergo mitosis.
💡 Think of mitosis as a "copy machine" that makes exact duplicates of cells, while meiosis is more like shuffling and dealing cards—creating unique combinations in each resulting cell!
In contrast, meiosis produces four genetically different cells from a single parent cell. These are haploid cells (with a single set of chromosomes) and function as sex cells or gametes. Meiosis is essential for sexual reproduction, creating the diversity that makes each of us unique.
