Cell Theory The cell is the basic unit of life. All livings are composed of cells. Unicellular & multicellular. All cells come from pre-existing cells. Important organelles in a cell Nucleus: Contains the cell’s DNA. ‘Brain’ of the cell. Mitochondrion: Site of respiration. Provides the energy for the cell to function. Ribosomes: Site where proteins are made (including enzymes) Vacuole: Storage. Cytoplasm: Watery fluid that all the cell organelles float in. Unicellular orgasms: Made of only one cell. Multicellular: Made up of more than one cell e.g. Humans. Research Microorganisms are small, unicellular organisms that can be both beneficial & dangerous. Find out about One beneficial microorganism used in the food industry. -What is its scientific name? -What does it do for our food that is helpful? Other (work for Mr Derrin) ANTON VAN LEEUWENHOEK (lay-van-hook) Robert hook looked at cork to find cells Matthias Schleiden & Theodore Schwann made up the cell theory``
