  2. Endoplasmic reticulum - Wikipedia

    en.wikipedia.org/wiki/Endoplasmic_reticulum

    The functions of the endoplasmic reticulum can be summarized as the synthesis and export of proteins and membrane lipids, but varies between ER and cell type and cell function. The quantity of both rough and smooth endoplasmic reticulum in a cell can slowly interchange from one type to the other, depending on the changing metabolic activities ...

  3. Cell wall - Wikipedia

    en.wikipedia.org/wiki/Cell_wall

    Diagram of the plant cell, with the cell wall in green. Cell walls serve similar purposes in those organisms that possess them. They may give cells rigidity and strength, offering protection against mechanical stress. The chemical composition and mechanical properties of the cell wall are linked with plant cell growth and morphogenesis. [11]

  4. Endomembrane system - Wikipedia

    en.wikipedia.org/wiki/Endomembrane_system

    The endoplasmic reticulum (ER) is a synthesis and transport organelle that branches into the cytoplasm in plant and animal cells. [3] The Golgi apparatus is a series of multiple compartments where molecules are packaged for delivery to other cell components or for secretion from the cell. [ 4 ]

  5. Cell (biology) - Wikipedia

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

    The cell wall acts to protect the cell mechanically and chemically from its environment, and is an additional layer of protection to the cell membrane. Different types of cell have cell walls made up of different materials; plant cell walls are primarily made up of cellulose, fungi cell walls are made up of chitin and bacteria cell walls are ...

    changed the smooth endoplasmic reticulum to look as a part of the rough ER. made ribosome smaller and more attached to the rough endoplasmic reticulum; made small membrane vesicles smaller and yellow. changed Golgi vesicles to Golgi body and added the actual Golgi vesicles. grouped elements that belonged together. made the file an SVG

  7. Cellular compartment - Wikipedia

    en.wikipedia.org/wiki/Cellular_compartment

    The nucleolus within the nuclear envelope is the location of ribosome synthesis. The destination of synthesized ribosomes for protein translation is rough endoplasmic reticulum (rough ER), which is connected to and shares the same membrane with the nucleus. The Golgi body is also near the rough ER for packaging and redistributing. Likewise ...

  8. Endoplasm - Wikipedia

    en.wikipedia.org/wiki/Endoplasm

    Smooth endoplasmic reticulum makes hormones and lipids, degrades toxins, and controls cellular levels of calcium. Though most control of cell division is present in the nucleus, the centrosomes present in the endoplasm assist with spindle formation. The endoplasm is the site of many activities necessary for the cell to maintain homeostasis. [2]

  9. Microsome - Wikipedia

    en.wikipedia.org/wiki/Microsome

    Rough (containing ribosomes) and smooth (without ribosomes) microsomes are made from the endoplasmic reticulum through cell disruption. These microsomes have an inside that is exactly the same as the endoplasmic reticulum lumen. Both forms of microsomes can be purified by a process known as equilibrium density centrifugation. Rough and smooth ...
