Photosynthesis is a complex process in which ____________________ is converted into
chemical energy in ________________________ molecules. This process occurs within the
_______________________________ (a cell organelle) and specifically within the thylakoid
membrane (where __________________________ occur) and the stroma (where
__________________________ occur). (1) During the light-dependent reaction,
_______________ is changed and light energy is converted into chemical bond energy to
produce ______________, __________________ , and ____________________ gas. (2) During
the light-independent reaction (also known as the Calvin cycle), ______________________ gas,
___________________, and _________________ react to produce sugars. The ATP and
NADPH are used up and they then become _____________ and ____________. Chloroplasts
are found in plant cells (e.g., lettuce, onion) and photosynthetic protists (e.g., euglena).

Putting It All Together:
Now label the chloroplast below to show how the thylakoid membranes and the stroma work
together. You are labeling what goes in and what comes out and what is cycled around.

Answer:
Photosynthesis is a complex process in which visible sunlight is converted into chemical energy in
carbohydrate molecules. This process occurs within chloroplast and specifically within the thylakoid
membrane (where light-dependent reactions occur) and the stroma (where light-independent reactions
occur). During the light-dependent reaction, water is oxidized and light energy is converted into chemical
bond energy generating ATP, NADPH, and oxygen gas. During the light-independent reaction (also
known as the Calvin cycle), carbon dioxide gas, ATP, and NADPH react, forming
phosphoglyceraldehyde, which is then converted into sugars. Chloroplasts can be in plant cells (e.g.,
lettuce, onion) and photosynthetic protists (e.g., euglena).
