level questions: Cells
| Question | Answer |
|---|---|
| What are Eukaryote Organisms? | -This is simply Organisms that are made from Eukaryotic Cells - Complex Cells |
| What are Prokaryotes? | -These are Organisms that are made from Prokaryotic Cells - Simple Cells |
| What is in an Animal Cell, and States its Function | -Nucleus: Has the DNA in Chromosomes that Controls what the Cell Does -Cytoplasm: Gel-ish Substance that has Most of the Chemical Reactions -Mitochondria: Places where Respiration happens. Simple -Cell Membrane: Has all of the Cell Together, and Controls what goes In and Out. Also has Receptor Molecules that are used for Communication. |
| What is in a Plant Cell, and State its Function | -Has Everything that's in a Animal Cell +.. -Cell Wall: Supports the Cell. Simple -Chloroplasts: The Hub for Photosynthesis, and has a Green Substance called Chlorophyll. |
| What's in a Prokaryotic Cell? State its Function | -Chromosomal DNA: Simply a Long Circular Chromosome that controls the Activity of the Cell. It can just float around in the Cytoplasm -Plasmids: This is Loops of DNA that aren't connected with the Chromosome. They mainly contain Genes that are Resistance for Drugs [eg] which can be Passed between Bacteria |
| How can Cells be Studied? | -Microscopes allow us to See Cells, as it has Lens which Magnify Images. Resolution also Increases meaning we can Actually see Better in more Focus. |
| What does Resolution mean? | -This simply means how well a Microscope can Separate 2 Points that are Close Together - Detail in a Nutshell |
| What is a: 1. Light Microscope 2. Electron Microscope 3. Transmission Electron Microscopes | 1. Light Microscopes use the Light to see Nuclei and Chloroplasts. They can give Colour, but compared to the Other Microscopes, they aren't that Specific 2. Electron Microscopes use Electrons to Depict Images, like Plasmids or Viruses. They can give a Better Resolution and Magnification then Light Microscopes - but more Expensive and No Colour 3. TEM's can give a very High Magnification, but can't be Moved and are Stupidly Expensive. They also can't be used to see Living Tissues. |
