The variable that you measure or observe in an experiment?
Dependent variable
What is ER and what does it do?

All organisms get the energy they need from the sun through a process that changes light energy into chemical energy called?
Photosynthesis
Name two types of transport through a cell wall and what distinguishes them from each other?
Passive transport (does not require energy) Active transport (requires the cell to use its own energy)
