Skill 2: Explain how plants capture light energy from the sun and store it in the bonds of glucose. Are they storing or releasing energy? Are they making or breaking down glucose?

In science, it is important for researchers to share their results so that others can continue their work and build on their findings. Joseph Priestley and Jan Ingenhousz both worked to discover the connection between plants and air. What did they discover between them about the connection between plants and air?

On the SOL test, they are likely to mention "thylakoids" or "thylakoid membranes." You must remember that these are the part of a chloroplast that contains the chlorophyll (green pigment) which collects the energy from sunlight used in photosynthesis.

- Light dependent reactions
- Calvin cycle
- ATP
- ADP
- NADPH
- NADP+
- Carbon dioxide (CO2)
- Water (H2O)
- Glucose
- Oxygen (O2)
- Energy (sunlight)
Be sure that you can fill out all of the labels from memory and understand how the two parts of photosynthesis work together to create glucose. The two parts are the LDR (Light Dependent Reactions) which "charge the batteries" to power the Calvin Cycle which creates the glucose.
