Chapter 1: The Cell and Cell Division

The Cell: Cells are traditionally divided into three parts, the cytoplasm, the plasma membrane (or cell membrane) and the nucleus.The cytoplasm includes everything between the plasma membrane and the nuclear envelope. The nucleus is the nuclear envelope and its contents. Using the virtual microscope and the BLOOD and SPINAL CORD slides, find examples of these structures.

Cell Division: Mitosis is a continuous process but has named stages. We will illustrate cells passing through these stages by using projected slides. You should then find examples of four stages on your virtual microscope slide of MAMMALIAN CELLS.

In the BLOOD smear, examine white blood cells, each having a darkly stained nucleus.

In the SPINAL CORD cross section examine the large, irregularly shaped motor neuron cell bodies found in the anterior horn.

Mitosis is a continuous process but has four named stages. You should be able find examples of all four stages on the virtual microscope slide of allium ROOT TIPS.
