Cells and Cell Structure

Cells and Cell Structure

1. Bacteria

   • Contains, Ribosomes, Cytoplasm, Cell membrane, Cell Wall, Capsule and Bacterial Flagellum
   • DNA is in the cytoplasm as there is no Nucleus
   • All bacteria are living organisms made up of just one cell
   • NO NUCLEUS

2. Functions

   • Nucleus
     • Contains genetic material, which controls the activities of the cell
   • Cytoplasm
     • Most chemical processes take place here, controlled by enzymes
   • Cell membrane
     • Controls what leaves and enters the cell
   • Cell Wall
     • Strengthens and supports the cell
   • Ribosome
     • Proteins are made here
   • Vacuole
     • Filled with cell sap, a weak solution of sugar and salts
   • Mitochondria
     • Most energy is released by respiration here
   • Chloroplasts
     • Contain Chlorophyll which absorb sunlight so photosythesis can occur

3. Plant

   • Contains, Cell Wall, Cell Membrane, Nucleus, Cytoplasm, Chloroplasts, Mitochondria, Ribosomes, Vacuole
   • Similar to an animal cell

4. Yeast

   • Yeast cells clone themselves to reproduce, this is called asexual reproduction
   • Yeast cells don't carry out photosythesis
   • Contains, Ribosomes, Cytoplasm, Mitochondria, Cell Wall, Vacuole Cell Membrane and a Nucleus

5. Animal

   • Contains, Nucleus, Mitochondria, Ribosomes, Cytoplasm and a Cell Membrane
   • Similar to a plant cell
