Apr 9, 2024 · Cell division – cell enters the cell cycle; Cell differentiation – cell takes on specialised form and function; Cell death via apoptosis; Stem Cells. Stem cells are immature cells that can go on to differentiate into various specialised, mature cell types within a certain lineage.
Cellular adaptation is the ability of cells to respond to various types of stimuli and adverse environmental changes. These adaptations include hypertrophy (enlargement of individual cells), hyperplasia (increase in cell number), atrophy (reduction in size and cell number), metaplasia (transformation from one type of epithelium to another), and ...
Jun 7, 2020 · Cells adapt to changing environments. Perturb a cell and it returns to a point of homeostasis. Perturb a population and it evolves toward a fitness peak. We review quantitative models of the forces of adaptation and their visualizations on landscapes.

Jan 28, 2020 · 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.
One of the key differences in mitosis is a single cell divides into two cells that are replicas of each other and have the same number of chromosomes. This type of cell division is good for basic growth, repair, and maintenance. In meiosis a cell divides into four cells that have half the number of chromosomes.

Jun 20, 2018 · An adaptation, or adaptive trait, is a feature produced by DNA or the interaction of the epigenome with the environment. While not all adaptations are totally positive, for an adaptation to persist in a population it must increase fitness or reproductive success.
