The microtubule-organizing center (MTOC) is a structure found in eukaryotic cells from which microtubules emerge. MTOCs have two main functions: the organization of eukaryotic flagella and cilia and the organization of the mitotic and meiotic spindle apparatus, which separate the chromosomes during cell division.
In smaller cells, the diffusion of molecules is more rapid, but diffusion slows as the size of the cell increases, so larger cells may need cytoplasmic streaming for efficient function. [1] The green alga genus Chara possesses some very large cells, up to 10 cm in length, [2] and cytoplasmic streaming has been studied in these large cells. [3]
He coined the term cell (from Latin cellula, meaning "small room" [41]) in his book Micrographia (1665). [42] [40] 1839: Theodor Schwann [43] and Matthias Jakob Schleiden elucidated the principle that plants and animals are made of cells, concluding that cells are a common unit of structure and development, and thus founding the cell theory.
The U.S. government is allowing the sale of chicken made from animal cells. ... Press and the NORC Center for Public Affairs Research found half of U.S. adults said that they are unlikely to try ...
The 3D Cell Culturing by Magnetic Levitation method (MLM) is the application of growing 3D tissue by inducing cells treated with magnetic nanoparticle assemblies in spatially varying magnetic fields using neodymium magnetic drivers and promoting cell to cell interactions by levitating the cells up to the air/liquid interface of a standard petri ...
Original - This is a schematic view of an typical animal cell. An animal cell is a form of eukaryotic cell that makes up many tissues in animals. Reason well labeled, encyclopedic, high quality SVG. i am renominating it sepratly because last time it was one of the concern.

For the first time, the Food and Drug Administration has cleared lab-grown meat, created from cultured animal cells, for human consumption, the agency announced on Wednesday.. The FDA green light ...
Plant cells have cell walls and a cell membrane,unlike plant cells,animal cells don't have cell walls,this makes it harder to stack animal cells.This is also another reason that plants stand tall and firm.Another thing that seperates these two cells is that plant cells have chlorapast and animal cells don't when the chlorapast dies the plant or ...
