Vacuoles

Picture
Plant cell and animal cells have vacuoles Vacuole carry out hydrolysis. food vacuoles are formed by phagocytosis. Feshwater protists have contractile vacuoles that pumps excess water out of it's cells that maintain the appropriate concentration of salt and other molecules. Mature plant have a large central vacuole that is enclosed by tonoplast. Cntral vacuoles are made up of smaller vacuoles that clump together over a period of time. They derived from the ER and the Golgi apparatus. The tonoplast act as a selective barrier as what can come in and out of the membrane. The vacuole is to reserve important organic compounds. It is also plants main repository of inorganic ions. It play a major role in grow for plant cells.
