| Question | Answer |
| Cell Theory | the fundimental building blocks of all living cells |
| Two Types of Organisms | Unicellular Multicellulas |
| Exceptions to the Cell Theory | Striated muscle cells Giant algea Fungi with septette hypta |
| Types of microscopes and what is used to be able to see the structures. | Light microscope: beam of light Electron Microscope: beam of electrons |
| Resolution of Naked Eye Light Microscope Electron Microscope | Naked eye = 0.1mm Light microscope = 0.0002 Electron microscope = 0.000001 |
| Formula of Magnification | Observed size / Actual size |
| 7 Functions of Life | Reproduction Response Growth Metabolism Nutrition Exertion Homeostasis |
| Why is there a limit to cell size? | Surface Area = Area/Volume If surface area is too small it would take too long for particles to pass through the membrane and if the cell is too small it can overheat |
| Cell Differentiation | The division of labour When cell specialise and have one function or when a certain gene is being expressed |
| Stem Cells | Divide infinitely Only cell that can specialise into any type of cell Have therapeutic uses |
| The process of stem cells differentiating | |
| TheraPutic Uses Of stem cells | Regenate tissues in the lab Transplanting blood stem cells to regenate blood in patient |
| Label Prokaryotic Cell | |
| How do Prokaryotic Cells Divide | Binary Fission |
| Animal Cell | |
| Plant Cell | |
| Structure & Function Of Nucleus | Found In Plant&Animal Cells Has a double membrane with pores 'Brain of Cell' Contains Chromosomes Site for DNA replication Site for Ribosome synthesis |
| Structure&Function of Rough Endoplasmic Reticulum | Found in both Animal&Plant Flattened membrane sacs Site for protein synthesis |
| Structure&Function Of Smooth ER | Found in Both Plant&Animal Flattened membrane sacs Site for cellular products such as hormones&lipids |
| Structure&Function of Ribosomes | 80s Found in Both Animal&Plant Site for protein synthesis |
| Structure&Function of Golgi apparatus | Found in both Animal&Plant Processes and packages proteins before they're shipped out of the cell |
| Structure&Function Of Mitochondria | Found in both Animal&Plant Double membrane Inner structure called cristea Contains fluid called matrix Produces energy in the form of ATP |
| Structure&Function of Lysosome | Found in animal cells only Contain digestive enzymes which can be used to breakdown food or breakdown organelles or whole cell |
| Structure&function of chloroplast | Found in plant cells only double membrane contains chlorophyll green pigment |
| Structure&Function of Vacuoles&Vesicles | Found in Both store food and substances used for transport inside the cell |
| Function&Structure of Microtubules&Centrioles | Found in animal cells Movement of chromosomes during cell division |
| Structure&function of Cilia&Flagella | Found in both whip like structures help the cell move |
