Vocabulary Review Organelles Contains the cell’s genetic material and controls the cell’s activities nucleus Supports & protects the plant cell Cell wall Make ribosomes nucleolus Filled with enzymes that allow it to break down food into particles that the cell can use lysosome Synthesizes proteins using coded instructions that come from the nucleus ribosome Converts food into compounds that the cell uses for growth, development, & movement and releases energy mitochondrion Name two organelles that help provide cells with energy. Mitochondrion & chloroplast Regulates which materials enter & leave the cell Cell membrane Stores water, salts, proteins & carbohydrates for the cell vacuole Assembles lipids & modifies proteins Endoplasmic reticulum Allows materials to come in and go out of the nucleus Nuclear envelope Uses enzymes to attach carbohydrates & lipids to proteins & sends them to their final destination in vesicles Golgi apparatus Thread-like structures that pass on genetic information from one generation to the next chromosomes Helps cells maintain shape and also involved in cell movement (made of microtubules & microfilaments) cytoskeleton Uses energy from sunlight to produce energy-rich food molecules (photosynthesis) chloroplast
