Plant Cell Worksheet [Type the date] Name: _________________________ Plant Cell Vocabulary: Cell Wall: An outer covering on some cells; may be composed of cellulose, chitin, or peptidoglycan, depending on the kind of organism. Cell Membrane: Thin sheets of material composed of phospholipids and proteins. Chloroplasts: energy-­‐converting, membranous, saclike organelles in plant cells containing the green pigment chlorophyll. Cytoplasm: The portion of the protoplasm that surrounds the nucleus. Centrosome: Is an area in the cell where microtubules are produced. Vacuole: Large sacs within the cytoplasm of a cell, composed of a single membrane. Nucleus: The central body that contains the information system for the cell. Nucleolus: A nuclear structure composed of completed or partially completed ribosomes. Nuclear Membrane: The structure surrounding the nucleus that separates the nucleoplasm from the cytoplasm. Lysosome: Specialized, submicroscopic organelles that hold a mixture of hydrolytic enzymes. Rough ER: Rough endoplasmic reticulum appears “pebbled” by electron microscopy due to the presence of numerous ribosomes on its surface. Smooth ER: Smooth endoplasmic reticulum is so named because it appears smooth by electron microscopy. Ribosomes: Small structures composed of two protein and is involved in the assembly of proteins from amino acids. Golgi Body: A stack of flattened, smooth, membranous sacs; the site of synthesis and packaging of certain molecules in eukaryotic cells.
