Your body is composed of microscopic cells that are visible all the time ?True or false
Our body is composed of many microscopic cells. They are visible as a whole, but not individually. And all cells are not visible from outside. So the given statement is false.
Cells are defined as structural and functional unit of a living organism. Cells are of various shapes and sizes. A squamous epithelium cell is flat whereas a neuron is upto 1 meter in length. Cells of bronchus have projections called cilia whereas cells of small intestine have microvilli on their surface.
Our skin is formed of epithelial cells which are seen as a whole with our naked eyes. But individual structures of them are very small. This is why, human cells are microscopic in structure and not individually seen with naked eyes.
