LisosomasCreated by the Golgi, these help break large molecules into smaller pieces that the cell can use.
RibosomesOrganelles 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.These two subunits are necessary for protein synthesis in the cell. When both units are coupled with a special information unit called messenger RNA, produce proteins.Some ribosomes in the cytoplasm, but most are attached to the endoplasmic reticulum. While are attached to the ER, ribosomes produce proteins that the cell needs and also other proteins to be exported from the cell to other parts of the body to perform their respective functions.
Plasmatic MembraneThe membrane surrounding the cell is composed of two lipid layers called "lipid bilayer". Lipids are present in the plasma membrane are called "phospholipids".These lipid layers are formed by a number of fatty acids. The fatty acid forming this membrane has two different parts, a small part that loves the water-hydrophilicity head. Hydro means water and philic love. The other part of this fatty acid is water repellent. This part, the tail of acid, hydrophobic.Hydro means water and fóbicasignifica fear. The plasma membrane is organized so that the tails are each other inside and face directed towards the outside of the membrane.
NucleusThe nucleus is the control center of the cell. It is the major organelle of the cell and contains the DNA of the cell.DNA (deoxyribonucleic acid) contains all the information for cells to live and carry out their functions and reproduce.Withinthe core is another organelle called the nucleolus. The nucleolus is responsible for creating the ribosomes. The circles on the core surface are nuclear pores. This is where the ribosomes and other materials into and out of the cell nucleus.
Golgi ApparatusThis organelle of the cell is the one that is responsible for the correct classification and delivery of proteins produced in the ER.Like mail packages must have a correct shipping address, the proteins produced in the ER, must be correctly sent to their respective direction.In the cell, transport and sorting by the Golgi it is performed. It is a very important step during protein synthesis. If the Golgi apparatus makes a mistake in sending proteins to the right direction, certain functions in the cell can stop.This organelle is named after an Italian surgeon named Camillo Golgi. It was the first to describe this organelle in the cell. It is also the only organelle that is capitalized.
CentriolesThese are only found in animal cells and they enter in action when cells divide, helping the organization of chromosomes.
MicrovelliThe "microvilli" (singular "microvillus"), also known as "microvilli" (from Latin villus "hairiness") are fingerlike extensions (fingerlike) of some cells, which can extend the surface thereof, and therefore increase the exchange surface substances. Or microvilli microvilli usually found in cells (animal) epithelium
MitochondriaThis is where the energy go for each cell. This organelle saves energy of the nutrients in the form of ATP.Each cell type has a different number of mitochondria. There are more mitochondria in cells which have to perform much work, for example the muscle cells of the leg, heart muscle cells, etc. Other cells require less energy to do their work so they have fewer mitochondrias.
CytoplasmA term for the all content of a cell apart of nucleus. Although in the illustration is not represented, the cytoplasm contains mainly water.Some curious facts about water and the human body:- A human adult body contains 50 to 65 percent water.- The body of a child has a little more than 75 percent water in.- The human brain is about 75 percent water.
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.The rough endoplasmic reticulum is where most protein synthesis occurs in the cell. The function of smooth endoplasmic reticulum is synthesized lipids in the cell. The smooth ER also helps in detoxification of harmful substances in the cell.
Channels/poresA 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. These channels consist of certain proteins.
