Before a cell becomes specialised, it first starts out as a stem cell. The unique feature of stem cells is that they are pluripotent - they have the potential to become any type of cell in the body. These incredible cells are the ancestors of all cells in the body, from simple skin ce...
Glial cells actively interact with each other as well as with neurons and the vasculature and participate in the generation of the electroretinogram and spreading depression. Particularly prominent are the specialised M眉ller cells that span nearly the entire depth of the retina. M眉ller and ...

There are mainly three types of simple permanent tissues found in plants – Parenchyma, Collenchyma, and Sclerenchyma. However, among these three types of ground cells, only parenchyma cells consist of thin-walled, living, simple, and structure-wise unspecialised cells. Thus, these cells are ...
Stem cells are cells that have yet to specialize into a distinct cell type that serves a specific function or purpose within the body. There are different classifications of stem cells based on the cell's ability to differentiate into different cel...
Structure of Stomata Stomata are found on the aerial delicate organs and outer surface of the leaves in the form of minute pores. Stomatal pore is surrounded by two specialised epidermal cells called as guard cell. They are kidney shaped. The number of guard cells are two. ...
