Fermentation | happens instead of respiration when not enough oxygen |
Impermeable | substances can't move through membrane; barrier |

Passive Transport | doesn't use energy, substance moves freely |
Permeable | substances move freely through membrane |
Photosynthesis | plant process using light energy, water, and CO2 to make sugar (glucose) and oxygen |
