  2. Cell (biology) - Wikipedia

    en.wikipedia.org/wiki/Cell_(biology)

    Most cells are only visible under a microscope. Cells emerged on Earth about 4 billion years ago. All cells are capable of replication, protein synthesis, and motility. Cells are broadly categorized into two types: eukaryotic cells, which possess a nucleus, and prokaryotic cells, which lack a nucleus but

  3. Prokaryote - Wikipedia

    en.wikipedia.org/wiki/Prokaryote

    Diagram of a prokaryotic cell, a bacterium with a flagellum. A prokaryote (/ p r oʊ ˈ k ær i oʊ t,-ə t /; less commonly spelled procaryote) [1] is a single-celled organism whose cell lacks a nucleus and other membrane-bound organelles. [2]

    en.wikipedia.org/wiki/File:Average_prokaryote...

    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.

    en.wikipedia.org/.../Diagram_of_a_Prokaryote_cell

    Original – A diagram of the Prokaryotic Bacteria cell, showing its parts, which is the Pilus, Cytoplasm, Ribosomes, Nucleoid (DNA), Plasma membrane, Cell wall, Capsule, and the Flagellum. Reason It has a high educational value, as it shows the parts of a Prokaryote cell.

  6. Cell division - Wikipedia

    en.wikipedia.org/wiki/Cell_division

    The terminal cell elongates more than the deeper cells; then the production of a lateral bisector takes place in the inner fluid, which tends to divide the cell into two parts, of which the deeper one remains stationary, while the terminal part elongates again, forms a new inner partition, and so on.

  8. Cytoplasm - Wikipedia

    en.wikipedia.org/wiki/Cytoplasm

    An example of such function is cell signalling, a process which is dependent on the manner in which signaling molecules are allowed to diffuse across the cell. [9] While small signaling molecules like calcium ions are able to diffuse with ease, larger molecules and subcellular structures often require aid in moving through the cytoplasm. [ 10 ]

  9. Bacterial cell structure - Wikipedia

    en.wikipedia.org/wiki/Bacterial_cell_structure

    For example, Escherichia coli cells, an "average" sized bacterium, are about 2 μm (micrometres) long and 0.5 μm in diameter, with a cell volume of 0.6–0.7 μm 3. [1] This corresponds to a wet mass of about 1 picogram (pg), assuming that the cell consists mostly of water.
