Chapter 8;Photosynthesis Flashcards
Chlorophyll
Pigment that gives a chloroplast it’s green color; uses light energy to split water molecules during photosynthesis
Chloroplast
Organelles found in some plant cells and certain unicellular organisms where photosynthesis occurs
Stroma
Dick fluid contained in the inner membrane of a chloroplast
Thylakoid
Disc shaped sac in the stroma of a chloroplast; site of the light reactions of photosynthesis
Light reactions
Chemical reactions that convert the suns energy to chemical energy
Calvin cycle
Cycle in plants that make sugar from carbon dioxide, H+ ions and high-energy electrons carried by NADPH
Wavelength
Distance between adjacent waves
Electromagnetic spectrum
Range of types of electromagnetic energy from gamma waves to radio waves
Pigment
Chemical compound that determine a substances color
Carbon cycle
Process by which carbon moves from inorganic to organic compounds and back
Greenhouse effect
Process by which atmospheric gases trap heat close to earths surface and prevent it from escaping into space
