Photosynthesis Flashcards
1. Photon: A packet of light.
2. Chlorophyll: The light-absorbing green-coloured pigment that begins the
process of photosynthesis.
3. Chloroplast: A membrane-bound organelle in green plant and algal cells that carries
out photosynthesis.
4. Stroma: The protein-rich semiliquid material in the interior of a chloroplast.
5. Thylakoid: A disk-shaped sac in the stroma of a chloroplast.
6. Grana: Stacks of tylakoids.
7. Lamellae: Groups of unstacked thylakoids between grana.
8. Thylakoid Membrane: The photosynthetic membrane within a chloroplast that
contains light gathering pigment molecules and electron transport chains.
9. Thylakoid Lumen: A fluid-filled interior space enclosed by the thylakoid mem- brane.
10. ATP: A molecule containing three high energy phosphate bonds that acts as the primary
energy-transferring molecule in a living organism.
11. ADP: A molecule containing two high-energy phosphate bonds that may be
formed by breaking one of the phosphate bonds in ATP.
12. NADP+: A compound that accepts one hydrogen atom and two electrons form- ing
NADPH; it is an electron acceptor.
