Chapter 6 Photosynthesis

Capturing the Energy in Light Section 6-1 Capturing the Energy in Light

Photosynthesis Process by which part of the energy in sunlight is transferred to, and stored within, organic compounds

Energy for Life Processes Organisms that make their own food are called autotrophs, or producers Mainly plants Heterotrophs get their energy by eating other organisms All life depends on autotrophs

Reaction

Reaction Cellular respiration is opposite CO2+H2O+Energy from sunlight  C6H12O6+O2 Cellular respiration is opposite Photosynthesis and cellular respiration exist as a cycle Products of one reaction become reactants of the next

Reaction

Chloroplasts Chloroplast structure Inner and outer membrane Inside, flattened sacs called thylakoids stack forming grana Surrounding the grana is an aqueous solution called stroma Fig. 6-2, p. 112

Chloroplast

Properties of Light White light is actually an array of colors from red to violet (called the visible spectrum) Different colors within white light have different wavelengths

Properties of Light

Properties of Light When light strikes an object it can be absorbed or reflected Pigments are substances that absorb certain colors of light Light reflected does not contain that color

Plant Pigments Plants contain pigments that absorb many wavelengths of light, but not green That’s why plants look green!

Tomorrow’s Lab… We will be trying to determine how many pigments exist in green leaves Is there only one pigment, or are there several pigments? If so, how many??

Coming Up In Lecture… We will be discussing the reactions of photosynthesis… Light reactions (requiring light) Dark reactions (DO NOT require light but may occur in the presence of light)
