Bio chapter 7

Stroma

Fluid-filled space inside chloroplast; Calvin cycle happens here

Light Reactions

First stage of photosynthesis: uses light to make ATP and NADPH

NADPH

Carries high-energy electrons from light reactions to the Calvin cycle

Chlorophyll

Green pigment that absorbs light energy

Stoma

Tiny opening in a leaf where gases enter and exit

Photon

A packet of light energy

Granum

A stack of thylakoids

Carbon fixation

Adding CO2 carbon to an organic molecule during the Calvin cycle

Electromagnetic spectrum

The full range of electromagnetic radiation/light

Chloroplast

Organelle where photosynthesis occurs

Thylakoid

Flattened membrane sac; light reactions happen here

Wavelength

Distance between corresponding points on waves, like peak to peak

Calvin Cycle

Second stage of photosynthesis: uses CO2, ATP, and NADPH to make 3-carbon sugars

Photosystem

Group of pigments/proteins that captures light energy

Photosynthesis

Process that uses light energy to make sugars from CO2 and H2O, releasing O2
