Apr 9, 2024 · Cellular Adaptations. Cellular adaptations refer to the changes cells make in response to various stimuli or changes in their local environment. This can involve changing the number of cells or their morphological appearance. It can be physiological, which occurs in normal tissues or organs, or pathological, i.e., in disease states.
Aug 31, 2018 · Last modified: Aug 31, 2018. Hypertrophy, Hyperplasia, Atrophy and Metaplasia are the main four types of cellular adaptations. Adaptations are: Reversible changes. In the number, size, phenotype, metabolic activity or functions of cells. In response to the changes in the environment (stress).
Throughout development and adulthood, the process of cellular differentiation leads cells to assume their final morphology and physiology. Differentiation is the process by which unspecialized cells become specialized to carry out distinct functions. Stem Cells. A stem cell is an unspecialized cell that can divide without limit as needed and ...

Every cell in an organism derives from a single fertilised egg cell or zygote, which goes through various stages of specialisation to form the myriad of different cell types found in the body. Types of Specialised Cells. Red Blood Cells: Adapted to carry oxygen around the body. They possess a biconcave shape, lack a nucleus, and contain ...
Every cell has work to do. But different cells may have different jobs. In multicellular organisms, cells with the same type of job often work together. These groups of specialized cells form tissue. In turn, tissues often group together to form larger units, called organs. The heart is an organ; so is the stomach.
In such situations, cells must adapt to the new environment. These adaptations include hyperplasia, hypertrophy, atrophy, and metaplasia, and can be physiologic or pathologic, depending upon whether the stimulus is normal or abnormal. A cell can adapt to a certain point, but if the stimulus continues beyond that point, failure of the cell, and ...
Type of cell: Function: How it is adapted to its function: Root hair cell: They absorb water and minerals. A long thin 'hair' extends from each cell into the soil increasing the root's surface area.
