Cell structures come in various shapes and sizes dependent on their location within an organism and what life sustaining process it carries out. These can range from the globular protein of a red blood cell, designed to carry four oxygen molecules at a time to the tail like flagellum of a bacteria designed for mobility and penetration of organs within a body. There are two main types of cells, eukaryotic cells which are generally plant and animal cells and prokaryotic…...

In this virtual lab activity, you will be observing the cell cycle in the tip of an onion root. The root tip is responsible for the downward growth of the root and is one of the regions in the plant where cells are actively dividing and growing. Because of this, the root tip is an excellent system in which to observe the entire cell cycle, including the processes of nuclear division (mitosis) and cell division (cytokinesis). You will be submitting…...

Plant and animal cells have several differences and similarities. For example, animal cells do not have a cell wall or chloroplasts but plant cells do. Animal cells are round and irregular in shape while plant cells have fixed, rectangular shapes. Animal Cell Plant Cell Cell wallAbsentPresent (formed of cellulose) ShapeRound (irregular shape)Rectangular (fixed shape) VacuoleOne or more small vacuoles (much smaller than plant cells).One, large central vacuole taking up 90% of cell volume.

A cell may be defined as the basic unit that supports life. Organisms are usually made up of one or several cells. The cell membrane, or the plasma membrane, is common to all cells. The membrane is a thin and fragile structure, usually between 5 to 10 nm (nanometer) wide that separate cells from the surrounding environment. Because the plasma membrane is extremely thin, no hint may be detected when a cell section is investigated under a light microscope. It…...
