20 ORGANELLES By: Rose, Marshall, Kat, and Alana
Nucleus -Central membrane bound organelle that manages or controls cellular functions. -Positively charged center of an atom composed of neutrons and positively charged protons and surrounded by negatively charged electrons and eukaryotic cells. -The central membrane – bound organelle that manages cellular functions and contains DNA.
Cell Membrane Thin, flexible envelope that surrounds the cell. It allows the cell to change shape and controls what goes into and out of the cell. It contains carbohydrates, glycolipids, glycoprotein, cholesterol, integral protein, peripheral protein, filaments of cytoskeleton, cytoplasm, extra cellular fluid.
Cell Wall A fairly rigid structure located outside the plasma membrane that provides additional support and protection. -A rigid boundary in prokaryotic cells and cellulose in plant cells.
Nucleolus A small, typically round granular body composed of protein and RNA in the nucleus of a cell. It also makes ribosomes.
Ribosomes Ribosomes are found in the cytoplasm and on the endoplasmic reticulum. Their job is to make proteins needed in the cell for everyday life. The DNA tells the ribosomes which proteins to make, so that the cell can work efficiently. The nucleus also makes the ribosomes and sends them out for work.
Cytoplasm The cytoplasm is a jelly like material that is made up of mostly water. It is what fills the cell is most of the time clear in color. It is more like a gel then a watery substance, but it liquefies when it is shaken or stirred.
Golgi Apparatus Flattened stack of tubular membranes that modifies the proteins. It sorts proteins into packages and packs them into vesicles to be sent to the right place.
Vacuoles The blue dots are vacuoles Membrane Bound Compartments; storage areas. It also plays a role in intracellular digestion and release of cell waste. It has a variety of functions ranging from protection of a plant to endocytosis. Each plant cell also has a central vacuole, which is formed by the coalescence of smaller vacuoles.
