MiCROSCOPES ARE PERFECTED - OPTICAL MICRSCOPES Scientists can explore cells in more detail so the images are clearer and more magnified

MICROSCOPES ARE PERFECTED - ELECTRONIC MICROSCOPES It can magnify images up to one million times their actual size Scientists can observe tiny details inside cells and organelles
