Plant cell

Like all organisms, plants have cells. Plant cells have a nucleus with chromosomes and DNA, and they have mitochondria. Those are common to all eukaryote cells. But in some ways they are different from animal cells and the cells of other eukaryotes.

Diagrams of cell insides:

  • There are special cell-to-cell communication pathways known as plasmodesmata.[1] These are pores in the cell wall through which the cell content of adjacent cells (including endoplasmic reticulum) are continuous.[2]
  • They have a large central vacuole, a water-filled volume enclosed by a membrane.[5][6] The vacuole keeps the cell's turgor (stiffness), controls movement of molecules between the cytosol and sap, stores useful material and digests waste proteins.
