Joseph Foster Centrosomes are sites where protein dimers assemble into microtubules in a cell. These organelles function in the regulation of cell cycle progression and the formation of mitotic spindles. Centrosomes definition in biology The centrosome is the primary microtubule-organizing center (MTOC), regulating cell adhesion, motility, and polarity. The centrosome is composed of two …
Osmoregulation in cells is critical to the biology of every living thing. Its meaning in biology and some examples like osmoregulation in fish and humans will be discussed in this article. Osmoregulation definition in biology Osmoregulation is defined as the process by which the human body maintains a proper electrolyte balance in …
The meaning of homeostasis is the condition the body system undergoes in order to maintain its internal environment. Some examples of homeostasis in the body can be seen in the regulation of body temperature, maintenance of blood glucose level, and the defense of a bacterial or viral infection. Homeostasis meaning Homeostasis refers …
Autotrophs in ecology are organisms that produce or manufacture their food and these include plants, algae, and cyanobacteria which are some of the autotrophs examples. Almost all autotrophs get their energy from the sun (light) or from inorganic substances (chemical). Autotrophs meaning Autotrophs are also known as primary producers. They are organisms …
In heterotrophs, energy for life processes is obtained through the consumption of autotrophs. Some heterotrophs examples include members of the second and third trophic levels in an ecosystem. This article will discuss the types of heterotrophs, their meaning, and their role in ecology. Heterotrophs meaning Heterotrophs are living things that cannot produce …

In this article, chlorophyll will be explained with respect to the types, its structure, and ultimately the benefits of chlorophyll in humans and plants. Chlorophyll definition Chlorophyll is defined as a molecule produced …
The cytoskeleton simply means the skeleton of the cytoplasm of a cell. The cytoskeleton functions to help support all these internal organs in the cell with its structure and it can also be found in all cells, though the proteins that make it up differ between organisms. Cytoskeleton meaning The cytoskeleton is …
The phases of cell division occur in various stages of the cell cycle. These stages of cell division help in the production and maintenance of cells, tissues, and organs. The different types of cells that are involved in cell division will be discussed with appropriate diagrams and pictures. Definition of cell division …
