Cells B2 0.0 / 5 ? BiologyCells, tissues and organsGCSEAQA Created by: ICreated on: 05-04-14 11:35 Cell Membrane Controls what enters and leaves the cell. Holds cell together 1 of 16 Nucleus Contains genetic material that controls the activites of the cell 2 of 16 Ribosomes Where protiens are made 3 of 16 Mitochondria Where most of the reactions for respiration take place. Respiration releses energy the cell needs to work. 4 of 16 Cytoplasm Gel like substance where most of the chemical reactions happen. Contains enzymes that control these chemical reactions. 5 of 16 Cell Wall Animal cells only. Made of cellulose. Supports and strengthens cell. 6 of 16 Permanent Vacuole Contains cell sap, weak solution of sugar and salts. Storage space. 7 of 16 Chloroplasts Where photosynthesis occurs. Makes food for the plant, contain green substance called chlorophyll. 8 of 16 Bacterial Cell Single celld microrganism. No nucleus genetic materal floats in cytoplasm 9 of 16 Flagella Used for movement so the bacteria cell can swim 10 of 16 Capsule A Protective layer to help stop white bloods cell attacking bacterial cell 11 of 16 Piili Helps bacterial cell attach itself to tissues 12 of 16 How do yeast and bacterial cells reproduce? Asexually as there is only one parrent. The offsprig is genetically identical to the parent cell. 13 of 16 Benefits of using Yeast Used to produce bread- helps it rise as bubble produced in dough. Allow the fermentation of sugars- helps to mkae beer and wine. 14 of 16 Similarities between yeast and bacteral cells Both single-celled microorganisms. Both have ccytoplasm, cell membrane and cell wall 15 of 16 Diifusion The movement of particles from a high concentration to an area of low concentration 16 of 16
