Photosynthesis & Cell Respiration

By Camille Alam

Photosynthesis

What is Photosynthesis?

Photosynthesis is the process used by autotrophs to convert captured light energy (from the Sun), to chemical energy that can be used as food. The reactants are: Carbon Dioxide, Water, and Light Energy. The products are: glucose and energy.

Structures Required

-Thylakoid: a sac inside the chloroplast; this is where light is trapped and oxygen is released as a waste product

-Stroma: where glucose is made

-Stomata: tiny holes on the bottom of the leaf that allows gas and water vapor exchange to occur

-Light

-Pigment: molecules with atoms that absorb light

Cellular Respiration

What is Cellular Respiration?

Plants make sugar through photosynthesis and then use the mitochondria to break the sugar down into energy. Cellular respiration is the opposite of photosynthesis. The products of photosynthesis are the reactants of cellular respiration.
