CELLS 6.1 Photosynthesis- Pre AP Biology Study Notes – New Syllabus.
LEARNING OBJECTIVE
CELLS 6.1(a) Explain why the products of photosynthesis are ecologically important.
CELLS 6.1(b) Create and/or use models to explain the process of converting solar energy into chemical energy through photosynthesis.
CELLS 6.1(c) Use data to describe what factors affect rates of photosynthesis.
Key Concepts:
- CELLS 6.1.1 Photosynthetic organisms have the cellular structures to absorb solar radiation and convert it into chemical energy.
a. Photosynthetically active radiation wavelengths occur in the visible light spectrum.
b. Photosynthetic organisms have specialized pigments, membranes, and/or organelles that absorb solar radiation and convert it into chemical energy.
c. Photosynthetic organisms rely on properties of water, such as cohesion, adhesion, and surface tension, which result in capillary action.
d. Photosynthesis is divided into two stages: light-dependent and light-independent reactions.
1. Light-dependent reactions require sunlight energy and H₂O to transfer energy to ATP and NADPH. A byproduct of this process is oxygen.
2. Light-independent reactions use CO₂, ATP, and NADPH to produce sugars.
