  2. Plasmodesma - Wikipedia

    en.wikipedia.org/wiki/Plasmodesma

    A typical plant cell may have between 1,000 and 100,000 plasmodesmata connecting it with adjacent cells [11] equating to between 1 and 10 per μm 2. [ 12 ] [ failed verification ] Plasmodesmata are approximately 50–60 nm in diameter at the midpoint and are constructed of three main layers, the plasma membrane , the cytoplasmic sleeve , and ...

  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. Intercellular communication - Wikipedia

    en.wikipedia.org/wiki/Intercellular_communication

    Plant cells usually have thick cell walls which need to be crossed if neighboring cells are to communicate directly. Plasmodesmata form a pipe through the cell wall forming an ICC. The pipe has another smaller membranous pipe concentric to it connecting the endoplasmic reticulum of the two cells via a tube called the desmotubule. The larger ...

  5. DNA - Wikipedia

    en.wikipedia.org/wiki/DNA

    Cell division is essential for an organism to grow, but, when a cell divides, it must replicate the DNA in its genome so that the two daughter cells have the same genetic information as their parent. The double-stranded structure of DNA provides a simple mechanism for DNA replication .

  6. Cell wall - Wikipedia

    en.wikipedia.org/wiki/Cell_wall

    Cells interact though plasmodesmata, which are inter-connecting channels of cytoplasm that connect to the protoplasts of adjacent cells across the cell wall. In some plants and cell types, after a maximum size or point in development has been reached, a secondary wall is constructed between the plasma membrane and primary wall. [ 26 ]

  7. Multinucleate - Wikipedia

    en.wikipedia.org/wiki/Multinucleate

    Multinucleate cells (also known as multinucleated cells or polynuclear cells) are eukaryotic cells that have more than one nucleus, i.e., multiple nuclei share one common cytoplasm. Mitosis in multinucleate cells can occur either in a coordinated, synchronous manner where all nuclei divide simultaneously or asynchronously where individual ...

  9. Nuclear DNA - Wikipedia

    en.wikipedia.org/wiki/Nuclear_DNA

    Nuclear DNA is a nucleic acid, a polymeric biomolecule or biopolymer, found in the nucleus of eukaryotic cells.Its structure is a double helix, with two strands wound around each other, a structure first described by Francis Crick and James D. Watson (1953) using data collected by Rosalind Franklin.
