Cell Analogy Assignment Glossary Cell Membrane: The cell membrane is a thin membrane that surrounds the cytoplasm and holds the content of a cell. Its job is to protect the substances within a cell by allowing some substances in and keeping others out. It maintains the shape and helps support the cell. The Cell membrane has Phospholipids components that have polar heads and hydrophobic tail that face opposite of each other it allows some types of molecules to diffuse on the cell membrane. Cytoplasm: The cytoplasm consists of all the components outside of the nucleus and within the cell membrane of the cell. It contains the organelles of a cell. The cytoplasm has a jelly like appearance and is clear in colour. It’s made of mostly water, salt, organelles, and other organic molecules. Nucleus: The center core or brain of the cell. It controls the cellular activities of the cell such as growth and reproduction. Structures around the nucleus are organized into structures called chromosomes. Vacuoles: A membrane within a cell that contains a water type liquid. They are smaller in an animal cell and manage waste products. In Plant cells they maintain the water balance. In a plant cell they can occupy up to 90% of the cell. Vesicles: A bubble type structure that stores and sends out cellular products, and digests the waste within the cell. It`s a membranous sac that gets separated from the cytosol by at minimum one lipid bilayer. Mitochondria: The main power source of the cell that provides energy needed for the cell`s function. It breaks down sugar to create energy Depending on the cell type; one cell may have up to hundreds of mitochondria or thousands of mitochondria. New mitochondria come from the division of pre-existing mitochondria. Mitochondria are made up of structures such as cristae which are the inner matrix; it has a smooth outer layer, and has
