Cell Structure
Similar Parts of the Cell
If you compare the working cell to a factory, then the different parts of the cell function like the machines in a factory that work to make a product. These parts, or organelles, make proteins. Proteins are essential in just about every function in the body, and each organelle has a role in the production or transport of proteins. In this interactivity, investigate the organelles that all eukaryotic cells have in common. Click the player button to begin.

Cell Differences
While eukaryotic cells have many of the same organelles, plant and animal cells also have some key differences. Plant cells have a large centralized vacuole, chloroplasts, and a rigid cell wall. Animal cells lack a cell wall and contain centrioles. In this interactivity, explore the differences between plant and animals cells. Click the player button to begin.

Metabolic Processes - Multicelluar Organisms
Metabolic processes help the organism, whether unicellular or multicellular, maintain homeostasis and stay alive. These processes include: digestion, circulation, gas exchange, movement, excretion, obtain energy, protection, and reproduction. Multicellular organisms have different organs and organ systems that work together to perform these functions. In this interactivity, learn about the different metabolic processes that occur in multicellular organisms. Click the player button to begin.

Metabolic Processes - Unicellular Organisms
A unicellular organism, like an amoeba or a paramecium, must also perform life processes. Because these organisms exist as single cells, they do not have specialized cells to carry out these functions. The organelles in these single-celled organisms must work together to conduct all life processes. Learn about the diversity of unicellular organisms by viewing Single-Celled Organisms from eMediaVASM. In the video clip, you will observe the differences and similarities between unicellular organisms.
