CW—“resists water pressure” HOW: it prevents the cell from exploding because it contains too much water (osmotic pressure) Lyso—“suicide bags” Eliminates organelles that no longer function well AND it can eliminate its whole cell if not functioning well HOW: it either “consumes” organelles OR it releases its digestive enzymes into the cell Nucleus—“like the main office in a factory” chromosomes (genetic library) Nucleolus (produces ribosomes) HOW: sends detailed instructions (RNA) to the factory (ribosomes) WHEN NEEDED Proteoplastids—“stores proteins” NOT a result of sunlight, even though they are found in plant cells HOW: proteins are assembled by the ribosomes and given a membrane by the RER (packaged) RER—“transport network” HOW: it is a tube-like membrane Also functions in detoxification Golgi—“modify/sort/package”, also prepare these materials for export from the cell Vacuole—“storage units” Central—all eukaryotes (plant-1 large, animal-many small), largest structure in the plant cell, main job is to provide internal support; in animal cells, small like a mitochondria, main job is to store nutrients Contractile—found in protists, requires E to function properly Microtubules—“skeletal” Forms a spindle—functions in the process of mitosis SER—“tubular” The whole structure is membrane bound— its like a flattened straw that’s bent and reshaped so that materials can be transported around the cell Ribos— Chloroplast—“photosynthetic plastid” HOW: converts solar E to chemical E Esolar + 6CO2 + 6 H2O C6H12O6 + 6O2 Mitochondria—“produces E for the cell (ATP) HOW: converts chemical E to usable (ATP) E C6H12O6 + 6O2 6CO2 + 6 H2O + EATP
