BSC2010L Skill Check Photosynthesis 1. Hypothesis: Blue Filter will block out any blue light from passing, not allowing photosynthetic activity to occur. 2. Prediction: If Blue Filter will block out any blue light from passing, not allowing photosynthetic activity to occur, then there will be no starch present. Page 165 Discussion: 1. 2.

Hypothesis: Photosynthesis will be present only on the green section color of the leaf. Prediction: If Photosynthesis will only occur on the green section of the leaf then starch will only be present there. Results: 2. Before I2KI Test: After I2KI Test: 3. The Green Pigment, Chlorophylls a and b supported photosynthesis.
