As the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated

4. Did the complete process of photosynthesis take place in the way you modeled it in this activity? Explain your answer.
Dafna1 [17]
Well I dont know exactly how you modeled your model in this activity (also, I notice this is a question from 2016), but I do know the two processes.

This is the process of making glucose in plants. Photosynthesis goes through two individual stages:  
Stage 1: L<span>ight dependent reaction</span> (depends on the presence of light; it can’t happen in the dark) 
Stage 2: Light independent (dark reaction) (works in the absence of light, but calling it a dark reaction might be misleading; It can just as well happen in the presence of light).
