Cells

• Prokaryote 


  single celled organism with no nucleus e.g. bacteria cell
• Eukaryote 


  organisms whose cells have DNA enclosed in a nucleus
• cell wall

  made of cellulose, provides strength and support. not found in animal cells
• cell membrane 


  controls movement of substances in and out of the cell (semi-permeable)
• nucleus 


  contains DNA and controls the activities of the cell
• mitochondria 


  where aerobic respiration takes place to release energy
• ribosomes 


  where proteins are made (protein synthesis)
• cytoplasm 


  where chemical reactions take place
• plasmid 


  small rings of DNA found in bacteria
• Chlorophyll 


  green pigment that absorbs sunlight for photosynthesis
• chloroplast 


  where photosynthesis takes place, contains chlorophyll
• permanent vacuole 


  filled with cell sap, keeps cell rigid. not found in animal cells
• cellulose 


  makes up plant and algae walls to give them strength, formed from glucose
• resolution 


  ability to distinguish between two points on an image (level of detail)
