  2. Plasmodesma - Wikipedia

    en.wikipedia.org/wiki/Plasmodesma

    The activity of plasmodesmata are linked to physiological and developmental processes within plants. There is a hormone signaling pathway that relays primary cellular signals via the plasmodesmata. There are also patterns of environmental, physiological, and developmental cues that show relation to plasmodesmata function.

  3. Desmotubule - Wikipedia

    en.wikipedia.org/wiki/Desmotubule

    A desmotubule is an endomembrane derived structure of the plasmodesmata that connects the endoplasmic reticulum of two adjacent plant cells. [1] [2] The desmotubule is not actually a tubule but a compact, cylindrical segment of the ER that is found within the larger tubule structure of the plasmodesmata pore. [3]

  4. Plant cell - Wikipedia

    en.wikipedia.org/wiki/Plant_cell

    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 ...

  5. Cell junction - Wikipedia

    en.wikipedia.org/wiki/Cell_junction

    Cell junctions are also especially important in enabling communication between neighboring cells via specialized protein complexes called communicating (gap) junctions. Cell junctions are also important in reducing stress placed upon cells. In plants, similar communication channels are known as plasmodesmata, and in fungi they are called septal ...

  6. Phloem - Wikipedia

    en.wikipedia.org/wiki/Phloem

    All of the cellular functions of a sieve-tube element are carried out by the (much smaller) companion cell, a typical nucleate plant cell except the companion cell usually has a larger number of ribosomes and mitochondria. The dense cytoplasm of a companion cell is connected to the sieve-tube element by plasmodesmata. [10]

  7. Outline of cell biology - Wikipedia

    en.wikipedia.org/wiki/Outline_of_cell_biology

    Light micrograph of a moss's leaf cells at 400X magnification. The following outline is provided as an overview of and topical guide to cell biology: . Cell biology – A branch of biology that includes study of cells regarding their physiological properties, structure, and function; the organelles they contain; interactions with their environment; and their life cycle, division, and death.

  8. Phragmoplast - Wikipedia

    en.wikipedia.org/wiki/Phragmoplast

    The functions of these proteins in the phragmoplast are presumably similar to their functions elsewhere in the cell. [4] Most research into phragmoplast MAPs have been focused on the midline because it is, first, where most of the membrane fusion takes place and, second, where the two sets of anti-parallel MTs are held together.

  9. Cytoplasmic streaming - Wikipedia

    en.wikipedia.org/wiki/Cytoplasmic_streaming

    The diameter of the vacuole can occupy around 80% of the cell's diameter. [11] Thus for a 1 mm diameter cell, the vacuole can have a diameter of 0.8 mm, leaving only a path width of about 0.1 mm around the vacuole for cytoplasm to flow. The cytoplasm flows at a rate of 100 microns/sec, the fastest of all known cytoplasmic streaming phenomena. [8]
