• what is staining?


  helps us view colourless cells to add contast and highlight organells
• what are organells?


  a subcelluar structure that has one or more specfic job to perform in the cell
• what is the equation for magnification?


  Magnification(x)=size of image(mm)/actual size(ym)
• animal cells are eukaryotes.There genetic material DNA is enclosed in nucleus and other structures are surrounded in membranes
• what is cytoplasm?


  a jelly like material which contains dissloved nutrients and salts structures called organelles
• what is a nuclues?


  contains DNA and controls cells activites
• what is mitrocondria?


  organelles that contain enzymes for areobic respiration
• what is cell membrane?


  controls what goes in and out of cell
• plant cells are eukaryotic.This means that they have a nuclues and other structures surrounded by membranes
• bacteria are prokaryote cells.They do not have a nucleus but instead have circular chromosomes
• accerlation=change in velocity/time
• dt graphs gradient is speed
• vt graphs is acceleration
• negative is backwards
• area under the graph is distance
