As a cooking ingredient, egg yolks are an important emulsifier in the kitchen, and are also used as a thickener, as in custards . The albumen (egg white) contains protein, but little or no fat, and may be used in cooking separately from the yolk. The proteins in egg white allow it to form foams and aerated dishes.

The term comes from the Latin word cellula meaning 'small room'. Most cells are only visible under a microscope.
Lysosome. Centrosome. Cell membrane. A lysosome ( / ˈlaɪsəˌsoʊm /) is a single membrane-bound organelle found in many animal cells. [ 1][ 2] They are spherical vesicles that contain hydrolytic enzymes that digest many kinds of biomolecules.

Saccharomyces cerevisiae cells shown with DIC microscopy. The human use of fungi for food preparation or preservation and other purposes is extensive and has a long history. Mushroom farming and mushroom gathering are large industries in many countries. The study of the historical uses and sociological impact of fungi is known as ethnomycology.
In biology, cell theory is a scientific theory first formulated in the mid-nineteenth century, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells. Cells are the basic unit of structure in all living organisms and also the basic unit ...
