Plant cells have a cell wall, large central vacuole, and plasmodesmata. Like other eukaryotes, plants have a nucleus, plasma membrane, mitochondria, and other organelles, but plant cells differe from animal, fungal, and prtist cells in a number of different ways. The most obvious difference is the presence of a cell wall which surrounds each cell. It is composed primarily of cellulose, a complete cell. When plant cells divide, they must form a new cell wall between them, and this is accomplished by the formation of a phragmoplast, a system of microtubules oriented along the axis of cell division which helps to guide the deposition of cellulose. This is also an important difference from the "green algae", which produce a phycoplast during mitosis, in which the microtubules lie perpendicular to the axis of division. Only plants and charophytes divide their cells with the aid of a phragmoplast.
Neighboring cells in plants are connected across their cell walls by extensions of the......
