English: A simple diagram of a plant leaf cell, labelled with numbers. It shows the cytoplasm, nucleus, cell membrane, cell wall, mitochondria, permanent vacuole, and chloroplasts. Note going down the left the numbers are not sequential, this is to match the numbering on others in the series.
Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...
Cell membrane: Surrounds the cell's cytoplasm, regulates flow of substances in and out. Cell wall (except in Mollicutes, Thermoplasma) Outer covering that protects the cell and gives it shape. Cytoplasm: A watery gel that contains enzymes, salts, and organic molecules. Ribosome: Structure that produces proteins as specified by DNA. Nucleoid
The cytoplasm describes all the material within a eukaryotic or prokaryotic cell, enclosed by the cell membrane, including the organelles [1] and excluding the nucleus in eukaryotic cells. The material inside the nucleus of a eukaryotic cell and contained within the nuclear membrane is termed the nucleoplasm .
English: A diagram of a typical prokaryotic cell. This diagram, made in Adobe Illustrator, is an improved version of a similar diagram, Prokaryote cell diagram.svg, which was also made by LadyofHats. Besides general appearance changes, this version adds plasmids and pili, and notes that DNA is circular.

The phragmosome is a sheet of cytoplasm forming in highly vacuolated plant cells in preparation for mitosis. [1] In contrast to animal cells, plant cells often contain large central vacuoles occupying up to 90% of the total cell volume and pushing the nucleus against the cell wall. In order for mitosis to occur, the nucleus has to move into the ...
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.
