Vesicles transport materials within a cell. Vesicles are constantly forming, membrane-wrapped containers that transport things like protein through a cell.Know More
Vesicles that are artificially prepared are called liposomes. Naturally prepared vesicles are those made during exocytosis, endocytosis and phagocytosis. The membrane that encloses a vesicle is similar to the plasma membrane, and plasma membranes and vesicles can fuse together, making it possible to release the contents of the vesicle outside the cell.
Vesicles have various job functions. They aid in metabolism and enzyme storage and help control the balance inside and outside a cell. When vesicles malfunction, sometimes serious or fatal conditions may occur like diabetes and epilepsy.Learn more about Cells
To make a 3-D plant cell, gather materials like yarn, salt dough, candy, cake, clay or beads, and then determine what plant cell that the model will be fashioned after and use the materials to make it. Making a 3-D plant cell is fun and provides the ability to see in detail the parts of a plant cell.Full Answer >
Cells function similarly to factories in that both take up raw materials and use energy to produce waste and finished products. In the case of the cell, the finished products are proteins that can be used in building and operating the body.Full Answer >
The cell membrane is a lot like a wall or fence surrounding a city that keeps everything that is dangerous or harmful out, but lets in and out certain materials that are vital for the cell to survive. The chemicals on the cell membrane recognize which materials should be able to push through it, much like a gate in a fence or wall.Full Answer >
A lysosome is an organelle in an animal cell that contains enzymes to break down outside materials that enter the cell, as well as obsolete cell material. The lysosome acts as the digestive system for the cell, consuming proteins, carbohydrates and lipids.Full Answer >
