In this chapter, we learned about how cells make and produce energy, through the process of photosynthesis.
 * This chapter:

Objectives**: Where do plants get the energy they need to produce food? What is the role of ATP in cellular energy? What did the experimjents of Helmont, Priestley, and Inhgenhousz reveal about plants grow? What is the overall equation for photosynthesis? What happens in the light-dependant reactions? What is the Calvin cycle?

Autotrophs: things that use light energy from the sun to produce food. heteroproph: Obtain energy from food they consume. ATP: One of the principle chemical compounds that cells use to store and releqse energy. Photosynthesis: Plants use energy from the sunlight to convert water and sunlight into carbohydrates. pigment: Light absorbing molecule Clorophyll: captures light energy Thylakoid: saclike photosynthetic membrane photosystem: light collecting units of the chloroplast Stoma: Opening in the undersize of a leaf that allows carbon dioxide and oxygen to diffuse inside and outside of a leaf. NADP+: CArrier molecule that transfers high energy electrons from chlorophyll to other places. light dependant reactions: reactions of photosynthesis that use energy from light ATP synthase: large protein that uses energy from H+ ions Calvin cycle: reactions of photosynthesis in which energy from ATP and NADPH is used to build in energy compounds
