Plants are multicellular, eukaryotes organisms. They have membrane-bound organelles. A plant cell has a rigid cell wall, a central vacuole, plasmodesmata and plastids, which make it unique among all other type of eukaryotes cells. There are two types of reproduction in plants. 2  They can be asexual, when the cell splits in two, and sexual, when two cells combine to create one living cell. 3  Plant cells have cell walls in which they can store water. 4  Cell walls of plants are made up of cellulose, hemicellulose and pectin.
