ENDOSIS Meaning and
Definition
-
Endosis is a biological process referring to the internalization of materials into a cell through a process of invagination and subsequent engulfment. This mechanism is predominantly observed in eukaryotic cells and serves as a means for the cell to acquire nutrients, eliminate waste materials, and regulate cellular processes.
During endosis, the plasma membrane of the cell undergoes inward folding, forming a vesicle or pocket that encloses the external substances. This vesicle then pinches off into the cytoplasm, effectively bringing the materials inside the cell. The process can be further categorized into various types based on the nature of substances being taken in. For instance, phagocytosis involves the engulfment of large solid particles, while pinocytosis refers to the intake of dissolved substances or fluids.
Once the vesicle is internalized, it undergoes further processing within the cell. For example, digestive enzymes may be secreted into the vesicle, aiding in the breakdown of the engulfed materials. The resulting nutrients are then utilized by the cell, while any waste products are typically expelled through exocytosis.
Endosis plays a vital role in maintaining a cell's homeostasis and ensuring its survival. By allowing the cell to selectively take in and process external substances, endosis enables cellular growth, repairs damaged components, and facilitates communication between cells. Additionally, the process also contributes to the immune response by allowing specialized cells to engulf and destroy foreign particles or pathogens.
