Photosynthesis

Energy Plants cannot “eat” their food to obtain energy, so they must “make” their own food by carrying out photosynthesis. They are called autotrophs.

Photosynthesis Uses the energy of sunlight to convert water and carbon dioxide into high-energy sugars and oxygen. Takes place in the chloroplast.

Chemical Equation Copy at least the first and last. They are the same thing, but the last one is with the formulas. In addition to water and carbon dioxide, photosynthesis requires light and chlorophyll, a pigment found in chloroplasts.

Light-Dependent Reactions Requires sunlight. Absorbs sunlight to produce oxygen gas (O2) and convert ADP and NADP+ into the energy carriers ATP and NADPH. These provide the energy necessary to make the sugars for “food” in the next step.

Light-Independent Reactions or the Calvin Cycle Uses ATP and NADPH from the previous reaction to produce high-energy sugars. Does not require light.

Sugars Plants use these sugars produced to carry out cellular respiration.
