Cells for 200: List ten organelles and what they do. Scroll down to see answer. Nucleus: the brain of the cell, contains stringy and tangled DNA Nucleolus: makes ribosomes Cell/Plasma Membrane: Selectively permeable, only lets certain things through. Cell wall: Only on plants, made of cellulose (and lignin in wood), held together by pectin. Cytoplasm: contains microtubles (little protein tubes) and microfilaments (little protein fibers), forms cytoskeleton. Mitochondria: Makes energy (ATPs) Endoplasmic Reticulum (ER): Smooth (no ribosomes) and Rough (ribosomes attached). Ribosome: makes proteins, can be attached to ER or floating in the cytoplasm. Vacuole: stores waste, food, and/or water. Larger in Plants. Golgi body: sends food and water in vesicles. Lysosomes: stores digestive enzymes. Centrioles: helps cells divide (mitosis, only in animals) Chloroplast: Where photosynthesis occurs Plastid: two kinds: Leukoplasts for storage, Chromoplast for pigment (color) Cilia or flagella: many little hairs or long tail, respectively. Used for movement. | |
