The components discussed here are by no means all the components within a cell. We will discuss other components in greater detail during later investigations and you should consult your texts for examples and pictures. The cell membrane functions as a barrier, allowing certain things into and out of the cell. The cytoplasm provides the liquid environment which allows for the movement of cellular components. The cell membrane, nucleus, and cytoplasm function alike in both animal and plant cells.
Plants cells contain all of the structure of animal cells with the addition of other structures.
The cell wall acts as a rigid structure which provides support for growing plants. The central vacuole is a large structure which provides support and stores water and minerals the plant may need. This section deals with the cellular structure of plants and animals. Using a compound microscope, you will observe and sketch representative samples of both plants and animals. The purpose of the investigation is to familiarize yourself with the microscope while learning the similarities and differences in structure and function of plant and animal cells.
