Photosynthesis
The word photosynthesis can be separated to make two smaller words:
“photo” which means light and “synthesis” which means putting together.
Photosynthesis is the process by which plants make their own carbohydrates, specifically glucose, which can then be used to make energy.
What is needed for photosynthesis?
To make food, plants and plant-like organisms (like algae) need not just one but all of the following:
What happens during photosynthesis?
The photosynthesis process takes place primarily in the leaves of plants, specifically in organelles called chloroplasts. Each chloroplast contains a green chemical called chlorophyll which gives leaves their green color. Here is what happens in a brief "nutshell":

What is needed for photosynthesis?
To make food, plants and plant-like organisms (like algae) need not just one but all of the following:
- carbon dioxide
- water
- sunlight
- Carbon dioxide from the air passes through small pores (holes) in the leaves. These pores are called stomata.
- Water is absorbed by the roots and passes through vessels in the stem on its way to the leaves.
- Sunlight is absorbed by a green chemical in the leaves.
What happens during photosynthesis?
The photosynthesis process takes place primarily in the leaves of plants, specifically in organelles called chloroplasts. Each chloroplast contains a green chemical called chlorophyll which gives leaves their green color. Here is what happens in a brief "nutshell":
- Chlorophyll absorbs the sun’s energy.
- It is this energy that is used to split water molecules into hydrogen and oxygen.
- Oxygen is released from the leaves into the atmosphere.
- Hydrogen and carbon dioxide are used to form glucose or food for plants.
Why is photosynthesis so important?
By now you know that photosynthesis is one of the most important chemical reactions on the planet because it produces oxygen for us to breathe and grows plants for the ecosystem to have a start to the food chain.

Here's one of the videos that I showed in class. Turn off the sound and try narrating it yourself!
For a cute version of the Calvin Cycle, try this one! Plus, you can find out what NADPH stands for!!

I do favor the Bioflix animations. Very good for review!
