Cells with genetic material enclosed in a nucleus 1 of 30 What are the 8 things in a plant cell? nucleus, mitochondria, cell membrane, cytoplasm, ribosomes, a cell wall, chloroplasts, a permanent vacuole 2 of 30 What are the 5 things in an animal cell? nucleus, cytoplasm, mitochondria, ribosomes, cell membrane 3 of 30 What do the mitochondria do? It is the site of aerobic respiration - the release of energy 4 of 30 What do the ribosomes do? It is where protein synthesis occurs 5 of 30 What does the cell membrane do? It controls the passage of substances into and out of the cell 6 of 30 What does the cytoplasm do? It is where most chemical reactions happen 7 of 30 What does the nucleus do? It controls the activity of the cell 8 of 30 What does the cell wall do? It is made of cellulose, it strengthens the cell 9 of 30 What do chloroplasts do? They absorb light energy to make food 10 of 30 What does the permanent vacuole do? It is filled with cell sap 11 of 30 How are leaf cells specialised to carry out photosynthesis? It has many chloroplasts 12 of 30 What are the two types of microscope? Optical and Electron 13 of 30 Which microscope is used to study cells in finer detail? Electron 14 of 30 What is magnification? The number of times greater an image of an object is than the actual object 15 of 30 What is resolving power? The ability to produce an image that shows fine detail clearly 16 of 30 Is it better to have a higher resolving power or a lower resolving power to study cells in finer detail? higher 17 of 30 Is it better to have a higher magnification or a lower magnification to study cells in finer detail? higher 18 of 30 Which microscope has a higher magnification and a higher resolving power? Electron 19 of 30 Which microscope can be used to see sub-cellular structures? Electron 20 of 30 Is mitochondria a sub-cellular structure? Yes 21 of 30 Are ribosomes a sub-cellular structure? Yes 22 of 30 To observe an onion cell it must first be stained with _________ Iodine 23 of 30 Why do we stain onion cells before observing them? To make it easier to see because the layers of the onion are see-through 24 of 30 Why do onion calls not have chloroplasts? Because onions are grown underground, so there would be no point because without light it can't photosynthesize 25 of 30 What organelles are found in plant cells but not animal cells? Cell wall, Chloroplasts, permanant vacuole 26 of 30 What are prokaryotic cells? When genetic information is not stored in a nucleus 27 of 30 What are the 5 things in a bacteria? Cytoplasm, cell membrane, cell wall, plasmids, DNA 28 of 30 When observing an onion, what is the name of the piece of glass we put the onion on? A microscope slide 29 of 30 When observing an onion, what is the name of the piece of glass we put on top of the onion? A cover slip 30 of 30
