A reworked version of FileBiological_cellsvg. Diagram of a typical animal cell. Organelles are labelled as follows.
Ribosomes dots on rough reticulum walls Vesicle. Golgi apparatus or Golgi body Cytoskeleton. Eukaryotic cells are typically much larger than those of prokaryotes having a volume of around 10000 times greater than the prokaryotic cell.
They have a variety of internal membrane-bound structures called organelles and a cytoskeleton composed of microtubules microfilaments and intermediate filaments which play an important role in defining the cells organization and shape. Animal cells uniquely possess the cell junctions called tight junctions gap junctions and desmosomes. The common animals most people know are only about 3 of the animal kingdom.
Equally it might be arranged according to evolutionary relationships. When biologists look at animals they find things that certain animals have in common. Wikipedia is a free online encyclopedia created and edited by volunteers around the world and hosted by the Wikimedia Foundation.

In cell biology the centrosome is an organelle that is the main place where cell microtubules are organized. Also it regulates the cell division cycle the stages which lead up to one cell dividing in two. The centrosome was discovered by Edouard Van Beneden in 1883 and was described and named in 1888 by Theodor Boveri.

Plant cells have a nucleus with chromosomes and DNA and they have mitochondria. Those are common to all eukaryotic cells. But in some ways they are different from animal cells and the cells of other eukaryotes.
They have cell walls composed of cellulose and some other compounds. Pectin and sometimes lignin is secreted on the outside of the cell membrane. A Tissue forms part of an organ in plants or animals.
Tissues are groups of cells that work together to do a job in the body. They are a group of cells having the same origin structure and function. The cells look the same or almost the same.
The work the cells in a tissue do is the same or almost the same. The cell is the smallest living component of organisms and is the basic unit of life. In multicellular living things a collection of cells that work together to perform similar functions is called a tissue.
Various tissues that perform coordinated functions form organs. And organs that work together to perform general processes form body systems. Informative and lively Show What You Know is a quiz show for curious tweens and their grown-ups from Encyclopædia Britannica.
