Plant cells are eukaryotes. Like all eukaryotes they have membrane bound organelles and a nucleus. They also contain a cell wall and a chloroplast, the latter to allow for photosynthesis to occur. The ability for the plant cell to undergo photosynthesis enables them to be producers; harnessing the energy from the sun and converting it into energy sustains the tropic levels which the producer provides for.
Nucleus
The nucleus in a plant cell contains the genetic information that codes for the produciton of polypeptides that either directly or indirectly control metabolic pathways in the cell to enable it to live. Like in all eukaryotes, DNA is found in the linear form of chromosomes. Plant cells can be diploid, tetraploid, etc. and are both asexual and sexually reproducing organisms. The sex organs of flowering plants are the stamen (males) and the pistil (females); the stamen of the flower produces the haploid (or diploid if mother cell is tetraploid) daughter gamete in the form of pollen that originates in the anther. Coniferous plants use cones and gametangia use gametangium as sex organs. Asexual reproduction the plant cells use simple mitosis.
Vacuole
The vacuole of the plant cell is used minorly as a food storage and intracellular digestion, but is majorly used for maintaining turgor pressure to prevent wilting. This is done by utilising the low osmotic potential of the vacuole because of a high concentration of solutes. Water thus moves into the vacuole via osmosis from the cytoplasm and becomes turgid, pressing on the cell wall of the cell and making the cell itself turgid and keeping the plant erect.
Cell Wall
The plant cell wall is composed by Cellulose, as it is a polysaccharides made from a series chain of beta-glucose with 1,4-glycosidic bond. The plant cell wall offers structural protection to the cell itself.
