torturous information about the study of life

transforms light energy to chemical energy and uses carbon dioxide and water as starting materials. releases oxygen

• light absorbing organelles
• the site of photosynthesis
• found mostly in interior cells of leaves

the green color of chloroplasts

tiny pores in leaves where carbon dioxide enters and oxygen exits

membranous sacs suspended in the stroma (a thick fluid)

Thylakoids concentrated in stacks

• light energy
• Carbon dioxide+ water--->glucose+ oxygen gas         photosynthesis

chlorophyll in the thylakoid membranes absorbs solar energy, which is converted to ATP and NADPH

• uses the products of the light reactions to make sugar from carbon dioxide 
• ATP provides energy for sugar synthesis
• NADPH produced by light reactinos provides the high energy electrons that drive the synthesis of glucose fro carbon dioxide

solarpowered sugar factories

the distance between the crests of two adjacent waves

Full range of radiotion

participates directly in the light reactions and absorbs mainly blue-violet and red light

absorbs mainly blue and orange light. Conveys absorbed energy to chlorophyll A

absorb blue green light and absorb/dissipate excessive light energy that might damage chlorophyll
