A membrane-enclosed sac occupying most of the interior of a mature plant cell, having diverse roles in reproduction, growth, and development. peroxisome. sac made of membrane in the cytoplasm of a eukaryotic cell. endoplasmic reticulum (ER). An extensive membranous network in a eukaryotic cell, continuous with the outer nuclear membrane and composed of ribosome-studded (rough) and ribosome-free (smooth) regions.
Cell Membrane The cell membrane protects the cell and regulates what substances enter and leave the cell. Vacuole Most mature plant cells have one large vacuole. This sac within the cytoplasm stores water, food, waste products, and other materials.Chloroplasts These organelles capture energy from sunlight and use it to produce food for the cell.Golgi BodyRibosomesMitochondrionCytoplasm Plant Cell sx05_LEP_L_ch2.fm Page 64 Monday, September 27, 2004 11:53 AM Vacuole Some animal cells have vacuoles that store food, water, waste, and other materials.olgi Body The Golgi bodies receive materials from the endoplasmic reticulum and send them to other parts of the cell. They also release materials outside the cell. Cytoplasm The cytoplasm includes a gel-like fluid in which many different organelles are found.
