Gametes such as ova, sperm, and pollen begin as germ cells, … SpletCompare and contrast mitosis and meiosis. Both mitosis and meiosis are involved in making new cells; Both start with diploid (2 sets of chromosomes) o Interphase occurs before both, duplicating chromosomes before division o Both mitosis and meiosis go through PMAT (prophase, metaphase, anaphase, telophase) Meiosis goes through PMAT …

Splet1. Meiosis is a process that gives rise to a haploid cell from a diploid one. 2. Haploid cell is the one that has a single set of chromosomes. While diploid cells have a double set of chromosomes. 3. Body cells are examples of diploid cells. 4. Reproductive cells are examples of haploid cells.

SpletA special form of cell division needed to produce sex cells - for example, sperm and eggs with only one copy of each chromosome. Fusion of the sex cells creates a new individual with two copies of each chromosome. Many single-celled organisms reproduce by cell division and have a single copy of each chromosome. SpletMeaning.

Splet22. dec. 2024 · The cell cycle has two major phases: interphase and the mitotic phase (Figure 6.2. 1 ). During interphase, the cell grows and DNA is replicated. During the mitotic phase, the replicated DNA and cytoplasmic contents are separated and the cell divides. Figure 6.2. 1: A cell moves through a series of phases in an orderly manner. SpletAs with mitosis, DNA replication occurs prior to meiosis during the S-phase of the cell cycle.

SpletThe cell cycle. In eukaryotic cells, the cell cycle is divided into two major phases: interphase and mitosis (or the mitotic (M) phase). Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis.
