The cell is the basic structural, functional, and biological unit of all known living organisms.
Organisms can be classified as unicellular (consisting of a single cell; including bacteria) or multicellular (including plants and animals). Cells are of two types: eukaryotic, which contain a nucleus, and prokaryotic, which do not. Prokaryotes are single-celled organisms, while eukaryotes can be either single-celled or multicellular. Here you can see an animal eukaryotic cell.
Move arround the cell to discover all the organelles and cellular structures, that carry out specific functions necessary for normal cellular operation.
Channels/pores A channel in the plasma membrane of the cell. This channel consists of certain proteins whose function is to control the movement of nutrients and water in the cell.
Cytoplasm A term for the all content of a cell apart of nucleus. Although in the illustration is not represented, the cytoplasm contains mainly water.
Nucleus The nucleus is the control center of the cell. It is the major organelle of the cell and contains the DNA of the cell.
Golgi Apparatus This organelle of the cell is the one that is responsible for the correct classification and delivery of proteins produced in the ER.
Centrioles These are only found in animal cells and they enter in action when cells divide, helping the organization of chromosomes
Lisosomes Created by the Golgi, these help break large molecules into smaller pieces that the cell can use.
Mitochondria The cellular organelle responsible for supplying most of the energy necessary for cellular activity in the form of ATP.
Plasmatic Membrane The membrane surrounding the cell is composed of two lipid layers called "lipid bilayer"
Microvillus Are microscopic cellular membrane protrusions that increase the surface area for diffusion and minimize any increase in volume and are involved in a wide variety of functions.
Ribosomes Organelles that help in protein synthesis. Ribosomes are composed of two parts, called subunits. They are named for their size. A unit is larger than the other so called large and small subunits.
Endoplasmatic Reticulum (ER) It is a network of membranes in the cytoplasm of the cell. There are two types of RE. When the RE is attached ribosomes is called rough ER and smooth ER when lacking ribosomes in the ER.
