Topics related to "endocytosis"

endocytosis
endocytosis , in biology, process by which substances are taken into the cell . When the cell membrane comes into contact with a suitable food, a portion of the cell cytoplasm surges forward to meet and surround the material and a depression forms within the cell wall. The depression deepens and ... Read more
pinocytosis
pinocytosis A form of endocytosis in which the material enclosed is a liquid and there is no fusion with a lysosome. Pinocytosis may be a means by which macromolecules (e.g. hormones and proteins) are taken into a cell.... Read more
phagocytosis
phagocytosis The process by which foreign particles invading the body or minute food particles are engulfed and broken down by certain animal cells (known as phagocytes). The plasma membrane of the phagocyte invaginates to capture the particle and then closes around it to form a sac or vacuole. The ... Read more
membrane
membrane structure composed mostly of lipid and protein that forms the external boundary of cells and of major structures within cells. Membrane organization is based on a sheet two molecules thick—a double layer of lipids aligned with their long hydrocarbon tails tucked inside—st... Read more
Gram's stain
Gram's stain laboratory staining technique that distinguishes between two groups of bacteria by the identification of differences in the structure of their cell walls. The Gram stain, named after its developer, Danish bacteriologist Christian Gram, has become an important tool in bacterial taxonomy... Read more
cell
cell in biology, the unit of structure and function of which all plants and animals are composed. The cell is the smallest unit in the living organism that is capable of integrating the essential life processes. There are many unicellular organisms, e.g., bacteria and protozoans , in which the s... Read more
virus
virus parasite with a noncellular structure composed mainly of nucleic acid within a protein coat. Viruses usually are too small (100-2,000 Angstrom units) to be seen with the light microscope and thus must be studied by electron microscopes. In one stage of their life cycle, in which they are fr... Read more
