... Of The Components Seen Under A Light Microscope Cytoplasm: is a partly fluid material, which can flow slowly and in which many other substances are suspended such as large fat and protein molecules. Many of the chemical reactions take place in the cytoplasm, which will provide the cell with energy and allow it to build up larger molecules that it needs. Studying the cell further and using better more powerful microscopes has shown that the cytoplasm actually contains lots of small structures called organelles. These have different roles and separate the reactions. In a cell. Examples are mitochondria where energy is released and ribosomes where proteins are made in a cell. Plasma membrane: consists of two layers of phospholipids (a fatty substance) with some protein molecules embedded in them. The membrane protein performs several functions. Branched carbohydrate molecules attached to the outside of some membrane protein molecules give the cell its immunological identity. ...
