This video explores the fascinating process of photosynthesis in plants, focusing on key concepts such as:
Light and Dark Reactions: Understanding how light energy is harnessed to produce chemical energy through the light-dependent and light-independent reactions.
Gas Exchange: Examining the crucial role of carbon dioxide (CO2) in photosynthesis, including the significance of ambient CO2 (Ca), intercellular CO2 (Ci), and chloroplastic CO2 (Cc).
Photosynthetic Pathways: Exploring the different modes of photosynthesis: C3, C4, and CAM, and how they adapt to various environmental conditions.
This video will be beneficial for students, researchers, and anyone interested in plant biology and the intricate mechanisms that sustain plant life.
Summary:
Photosynthesis
• How a Plant Harnesses Light Energy to Make Chemical Energy
Respiration
• Turning Chemical Energy into Fuel for Growth, Development and Reproduction
Understanding Ca, Ci & Cc
Ca = Ambient CO2 concentrations
Ci = Intercellular CO2 concentrations
Cc = Chloroplastic CO2 concentrations
The chemical equation for photosynthesis can be summarized as follows:
6CO2 + 6H2O + light energy → C6H12O6 + 6O2
Light dependent reaction produced Oxygen, ATP and NADPH
Light indepoendent reaction/Calvin cycle produce sugar
Modes of photosynthesis
C3
C4
CAM
