The parts of the plant cell are as follows: Plants cell constitute of membrane bound nucleus and many cellular structures. These organelles carry out funct ions that are necessary for the proper functioning and survival of the cell. The cell orga nelles of the plant are enclosed by a cell wall and cell membrane.
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. Plant cell structure. 1  They have cell walls composed of cellulose and some other compounds. The cell wall gives the cell a definite shape. 2  There are special cell-to-cell communication pathways known as plasmodesmata. 3  These are pores in the cell wall through which the cell content of adjacent cells (including endoplasmic reticulum) are continuous. 4  They have plastids.
