Prokaryotes used photosynthesis and eukaryotes dont use photosynthesisb. Prokaryotes have a nucleus and eukaryotes do not have a nucleusc. Prokaryotes do not have DNA and eukaryotes do have DNAd. Prokaryotes do not have a nucleus and eukaryotes do have a nucleus e. Prokaryotes used photosynthesis while eukaryotes use respirationSample Question #3How is osmosis different from diffusion?a. osmosis refers to the movement of ions across the membrane while diffusion is a special type of osmosisb. osmosis is a special type of diffusion involving only waterc. osmosis requires energy and diffusion does notd. osmosis requires proteins and diffusion does notAll living things have:
