Cellular Biology
Cells are small To increase surface area:volume Efficient movement of molecules Efficient cellular processes
Organelles are smaller Subcellular structures that carry out functions Ex: chloroplasts allow for photosynthesis
Microscopes Magnify Magnification Making something small appear larger
Robert Hooke First person to describe the cell (1665)
