Cell Organelles

All animal cells will have these three things.

Cell Membrane, Nucleus, and Cytoplasm. These are called organelles or little organs. Each living cell is unique with it’s purpose, but most cells will have similar organelles. In fact all animal cells have the same organelles and plant cells have the same organelles. Some organelles are specific for plants and some for animals. Let’s talk about all eukaryotic cells first.

Cell Membrane
This is the outer layer of a cell. It controls what goes in and what goes out. The are a whole bunch of regulating proteins that control the flow of material that goes in and out of the cells. Certain smaller materials can flow in and out without any help from the proteins. This is called diffusion. Diffusion is the movement of particles/molecules from an area of high concentration to an area of low concentration. View the picture below.

Nucleus
This would be inside the cell. Most often referred to the control center of the cell. The genetic information is stored inside the nucleus. This gives the cell is job or it’s purpose for work in the larger scheme of things.

Cytoplasm-
This is a jelly-like substance inside the cell. It keeps all of the inside parts of the cell from bouncing or floating around too much. It’s almost like a placeholder for the other organelles.
