chapter on chemistry. Cells are considered to be the smallest structure that is alive. They are often too small to see without the aid of a microscope. All living organisms are composed of cells. The smallest organisms are composed of a single cell; larger organisms are composed of more than one cell. Similar kinds of cells may be arranged together to form a tissue. Tissues have specific properties and functions. For example muscle tissue is composed of muscle cells. It functions to move body

Methods for studying cells in the lab Centrifugation A centrifuge is a device for separating particles from a solution according to their size‚ shape‚ density‚ viscosity of the medium and rotor speed. Centrifugation can be used to separate cells from one culture or to isolate an organelle from the rest of the cell. The process relies on speed; the faster and longer the particle is centrifuged‚ the smaller the particles are that will be separated. Separation occurs by causing the larger particles

The cell cycle‚ or cell-division cycle‚ is the series of events that take place in a cell leading to its division and duplication that produces two daughter cells. In cells without a nucleus‚ the cell cycle occurs via a process termed binary fission. In cells with a nucleus‚ the cell cycle can be divided in three periods: interphase—during which the cell grows‚ accumulating nutrients needed for mitosis preparing it for cell division and duplicating its DNA—and the mitotic phase‚ during which the
