Unit 10 Plant Kingdom Photosythesis Terms Crossword

pigments that absorb light at different wavelengths and then pass energy onto chlorophyll a; protects chlorophyll a
molecule that is converted to ATP for energy storage
the main energy source for all cells; required for the Dark Reactions
Organisms that make their own food, able to convert light energy into chemical energy
absorb excessive light that would damage chlorophyll
color of the Chlorophyll a pigment in plants that absorbs light energy used to carry out photosynthesis; located in the reaction center of photosystems
organelle where photosynthesis occurs, captures sunlight and converts into chemical energy
A waxy covering on the surface of stems and leaves that acts as an adaptation to prevent plants from dehydrating
moves high energy electrons from PS2 and PS1 and uses the lost energy from the electrons to pump hydrogen ions into the thylakoid lumen/space
describes the electrons that are passed in a thylakoid membrane
One stack of thylakoids, more than one stack is called "grana"
cells that control the opening and closing of the stomata
___reactions of photosynthesis that use energy from light and water to produce ATP, NADPH and oxygen that is released into the atmosphere, Occurs in Thylakoids
Light ____ Reactions set of reactions in photosynthesis that do not require light; energy from ATP and NADPH is used to build high-energy compounds such as sugar; also called the Calvin cycle
An electron carrier involved in photosynthesis, which provides the high-energy electrons for the fixation of carbon dioxide into sugar in the Calvin cycle.
Released to the atmosphere via diffusion when water is split in PS2
the process that autotrophs use to convert sunlight into food (glucose) Requires Carbon dioxide and water to produce oxygen and glucose
A light capturing protein complex in the thylakoid membrane of a chloroplast; reduces NADP+ to NADPH.
A light capturing protein complex in the thylakoid membrane of a chloroplast; splits water into electrons, protons, and oxygen gas.
___ pigments includes Chlorophyll a the main pigment in
Stomata,the small openings on the undersides of most leaves through which oxygen, water and carbon dioxide can move
The solution that surrounds the thylakoids in a chloroplast; Calvin cycle happens here
sac-like photosynthetic "coin" like structure where the light reactions occur
process that splits water in PS2
