The plastid (Greek: ÏÎ»Î±ÏÏÏÏ; plastÃ³s: formed, molded â plural plastids) is a major double-membrane organelle found in the cells of plants, algae, and some other eukaryotic organisms. Plastids were discovered and named by Ernst Haeckel, but A. F. W. Schimper was the first to grant them a clear definition. Plastids are the site of manufacture and storage of important chemical compounds used by the cell.
Plasmodesmata-Plasmodesmata are small tubes that connect plant cells to each other, providing living bridges between cells. Plasma Membrane-All living cells have a plasma membrane that encloses their contents. In prokaryotes and plants, the membrane is the inner layer of protection surrounded by a rigid cell wall.lant Cell Structure Plants are unique among the eukaryotes, organisms whose cells have membrane-enclosed nuclei and organelles, because they can manufacture their own food.
