5A THE PROCESS OF C3 PHOTOSYNTHESIS Flashcards
learn about the inputs, outputs, and locations of the light-dependent and light-independent stages of photosynthesis.
photoautotroph
an organism capable of undertaking photosynthesis
photosynthesis
the process of capturing light energy to power the production of glucose and oxygen from carbon dioxide and water
What are the 2 inputs of photosynthesis?
carbon dioxide and water
What are the 3 outputs of photosynthesis?
glucose, oxygen, and water
mesophyll cell
a plant cell type found in leaves that contain large amounts of chloroplasts
chloroplast
a membrane-bound organelle only found in plant and photoautotroph cells that is the site of photosynthesis
chlorophyll
a chemical found in the thylakoids of chloroplasts. It is responsible for absorbing light energy in photosynthesis
stoma (pl. stomata)
a small pore on the leaf’s surface that opens and closes to regulate gas exchange
xylem
vascular tissue in plants responsible for transporting water and minerals from the roots to the leaves
what is the light-dependent stage?
it is the first stage of photosynthesis, where light energy splits water molecules into oxygen and hydrogen inside the thylakoid membranes. Also known as the light-dependent reactions.
thylakoid
a flattened sac-like structure housed inside the chloroplast. Each thylakoid is made up of a chlorophyll-containing membrane enclosing a lumen. Thylakoids are the location of the light-dependent stage of photosynthesis. A stack of thylakoids is called the granum.
granum (pl. grana)
a stack of thylakoids
NADPH
a coenzyme that is a proton (H+) and electron carrier in photosynthesis
ATP
adenosine triphosphate, a high-energy molecule that, when broken down, provides energy for cellular processes
photolysis
the process in which molecules are broken down by the action of light
