The light dependent reactions absorb energy from sunlight and transfer the energy to the light independent reactions that produce sugars.
"Explain how the Calvin cycle is a bridge between carbon in the atmosphere and carbon-based molecules in the food you eat."
Carbon dioxide is removed from the atmosphere by plants for photosynthesis. The carbon is incorporated into sugars and other carbon based molecules that are eaten by other organisms.
"Explain why the chemical equation for photosynthesis (below) is a highly simplified representation of the process. How is the equation accurate? How is it inaccurate? 6CO2 + 6H2O C6H12O6 + 6O2 "
The equation shows the general reactants and products of the process. However, it does not show intermediate steps. For example, carbon dioxide and water do not actually react with each other.
"Explain how both passive transport and active transport are necessary for photosynthesis to occur."
Active transport moves hydrogen ions against the concentration gradient in photosystem II. Passive transport occurs when hydrogen ions diffuse/flow through the channel bound to ATP synthase
use energy from the light-dependent reactions to make sugars. They occur in the stroma of chloroplasts.
Chloroplasts contain a light absorbing molecule called chlorophyll and this is the place in plants where photosynthesis takes place.
(light-dependent reactions capture the energy from the sunlight)1. Energy from sun is absorbed & oxygen is released (in the chloroplasts)2. energy transfers to molecules that carry energy like ATP (across the thylakoid membrane) (light-independent reactions use the energy to make sugars)3. Carbon dioxide molecules area used to build sugars (Energy from light-dependent reactions is used)4. simple sugar molecules are formed.

Suppose you wanted to develop light to help increase plant growth. What characteristics should the light have?
Glycolysis breaks down glucose in the cytoplasm before cellular respiration occurs in the mitochondria. The aerobic processes in the mitochondria use the products of glycolysis.
