Cell culture is one of the major tools used in cellular and molecular biology, providing excellent model systems for studying the normal physiology and biochemistry of cells (e.g., metabolic studies, aging), the effects of different toxic compounds on the cells, and mutagenesis and carcinogenesis. A typical protozoal cell (let us say Paramecium) is about 25 µm wide by 100 µm long.

Two Types of Cells Two Fundamentally Different Cell Architectures: 1) A prokaryotic cell 2) A eukaryotic cell 9.
Cells can get around this problem by growing projections, having a flattened form, or being long and thin.
Since microchannels are the same typical size as cells, lab-on-a-chip research soon focused on cell biology.
A DNA molecule contains a code that can be used by a cell to express certain genes.
It's much smaller than the human red blood cell, which is (on average) about 7 μm in diameter. It is the smallest biological, structural, and functional unit of all plants and animals.Therefore, cells are the 'Building Blocks of Life' or the 'Basic units of Life'. It contains about 10 13 human cells and also about 10 14 bacterial, fungal, and protozoan cells, which represent thousands of microbial species.
