Jul 8, 2024 · Cytokinesis: The cell divides its cytoplasm, resulting in two identical daughter cells. Meiosis: Generating Genetic Diversity. Meiosis is specialized cell division that reduces the chromosome number by half, creating four haploid cells, each genetically distinct from the parent cell.

Cell division is the process cells go through to divide. There are several types of cell division, depending upon what type of organism is dividing. Organisms have evolved over time to have different and more complex forms of cell division. Most prokaryotes, or bacteria, use binary fission to divide the cell. Eukaryotes of all sizes use mitosis to ...
Prokaryotic Cell Division
Prokaryotes replicate through a type of cell division known as binary fission. Prokaryotes are simple organism, with only one membrane and no division internally. Thus, when a prokaryote divides, it simply replicates the DNA and splits in half. The process is a little more complicated than this, as DNA must first be unwound by special proteins. Although the DNA in prokaryotes usually exists in a ring, it can get quite tangled when it is being used by the cell. To copy the DNA efficiently, it...
Eukaryotic Cell Division: Mitosis
Eukaryotic organisms have membrane bound organelles and DNA that exists on chromosomes, which makes cell division harder. Eukaryotes must replicate their DNA, organelles, and cell mechanisms before dividing. Many of the organelles divide using a process that is essentially binary fission, leading scientist to believe that eukaryotes were formed by prokaryotes living inside of other prokaryotes. After the DNA and organelles are replicated during interphase of the cell cycle, the eukaryote can...
Eukaryotic Cell Division: Meiosis
In sexually reproducing animals, it is usually necessary to reduce the genetic information before fertilization. Some plants can exist with too many copies of the genetic code, but in most organisms it is highly detrimental to have too many copies. Humans with even one extra copy of one chromosome can experience detrimental changes to their body. To counteract this, sexually reproducing organisms undergo a type of cell division known as meiosis. As before mitosis, the DNA and organelles are r...
1. Somatic cells are cells that fill the body, and must reproduce to repair damage. Gametic cells are cells that produce gametes. Which type of cell division do each type of cell undergo? A. Somatic= mitosis; Gametic= meiosis B. Somatic= mitosis; Gametic= meiosis and mitosis C.Somatic= mitosis and meiosis; Gametic= meiosis and mitosis 2. Mitochondr...
Apr 27, 2017 · Cytoplasm refers to the fluid that fills the cell, which includes the cytosol along with filaments, proteins, ions and macromolecular structures as well as the organelles suspended in the cytosol. In eukaryotic cells, cytoplasm refers to the contents of the cell with the exception of the nucleus.
Jul 14, 2023 · There are two forms of cell division: (1) direct cell division and (2) indirect cell division. Direct cell division is one in which the nucleus and the cytoplasm of the cell divide directly into two parts. This form of cell division is also referred to as amitosis.
Feb 23, 2023 · Cells in the body replace themselves over the lifetime of a person. For example, the cells lining the gastrointestinal tract must be frequently replaced when constantly “worn off” by the movement of food through the gut. But what triggers a cell to divide, and how does it prepare for and complete cell division?
May 30, 2017 · The cell cycle is a cycle of stages that cells pass through to allow them to divide and produce new cells. It is sometimes referred to as the “cell division cycle” for that reason. New cells are born through the division of their “parent” cell, producing two “daughter” cells from one single “parent” cell.

Aug 3, 2023 · The cytoplasmic cycle involves cell growth that alternates with cytokinesis. During growth, the cell accumulates nutrients and growth factors and doubles the contents of the cytoplasm. Eventually, the cytoplasm divides via cytokinesis to equally divide the cytoplasmic contents into two cells.
