Like all organisms, plants have cells. But in some ways they are different from animal cells and the cells of other eukaryotes.
Plant cell structure
They have cell wall composed of cellulose and some other compounds. Pectin, and sometimes lignin, is secreted on the outside of the cell membrane. This is different from the cell walls of fungi (which are made of chitin), and of bacteria, which are made of peptidoglycan. The cell wall gives the cell a definite shape.
There are special cell-to-cell communication pathways known as plasmodesmata. These are pores in the cell wall through which the cell content of adjacent cells (including endoplasmic reticulum) are continuous.
A large central vacuole, a water-filled volume enclosed by a membrane. The vacuole keeps the cell's turgor (stiffness), controls movement of molecules between the cytosol and sap, stores useful material and digests waste proteins and organelles.
Cell division by construction of a 'cell plate' late in cytokinesis is characteristic of land plants and a few groups of algae.
