Light Dependent Reaction• Light, water, NADP+, and ADP enter the thylakoid.• Oxygen, ATP, NADPH leave• Requires light to occur• Stores energy temporarily
![Page 5: Photosynthesis. Light Dependent Reaction vs. Light Independent Reaction](https://reader033.vdocument.in/reader033/viewer/2022042608/56649cd85503460f949a18fe/html5/thumbnails/5.jpg)
Light Independent Reaction
• Also known as Calvin cycle• ATP, NADPH, and CO2 enter• ADP,NADP+, and sugar exit• Stores energy for long period of time. • Does not need light to occur

Gas Exchange
• Stomata-– Openings in the leafs where gases can enter and
leave

• Which gas enters through the stomata?¿Qué gas entra a través de los estomas?
• Which gas leaves through the stomata?¿Qué gas se va a través de los estomas?

Photosynthesis is affected by…
• Sunlight• Water availability• CO2• Temperature

Chlorophyll
• Pigment that traps sunlight• Absorbs all colors but green• The chloroplast is green because green is reflected
