    Light microscope is the microscope that students are commonly used in the laboratory.

    They are used for studying cells and structures.

    Electronic microscope have a higher power of magnification than light microscopes. They make use of beams of electrons, instead og light. They magnify objects up to 500000 times, compared to only 1500 times in light microscopes.

    Coarse adjustment knob is a device that helps get a rough focus.

    Iris diaphragm regulates the amount of light entering the condenser.

    Magnification is the product of the power of the objective and the eyepiece.

    Cell membrane is a thin and flexible membrane. It encloses the cytoplasm and is differentially permeable, it allows only some substances to pass through. It controls the movement of materials into and out of the cells.

    Cell wall is a thick but fully permeable layer covering the cell membrane. It is made up of cellulose and it protects, supports and gives shape to plant cells.

    Iodine solution is added into the slide to make a certain cell structures more distinct.

    Cell division is a process by which a cell, called the parent cell, divides into two cells, called daughter cells. Cell division is usually a small segment of a larger cell cycle. In meiosis however, a cell is permanently transformed and cannot divide again.
