The Process That Feeds the Biosphere Photosynthesis: the conversion of light energy to chemical energy that is stored in glucose or other organic compounds (plants, algae, certain prokaryotes) Photosynthesis nourishes almost the entire living world directly & indirectly An organism acquires organic compounds it uses for energy & carbon skeletons by autotrophic or heterotrophic nutrition Autotroph: PRODUCER an organism that obtains organic food molecules w.o. eating other organisms or substances derived from other organisms (use energy from sun or oxidation of inorganic substances to make organic molecules from inorganic ones) Produce their organic molecules from CO2 & other inorganic raw materials obtained from environment ULTIMATE SOURCE OF ORGANIC COMPOUNDS

Gavin Morgan 11/9/2015 Chapter 8 2-Point Notes Photosynthesis combines CO2 and H2O, producing glucose and O2: 1. Photosynthesis takes place in three stages: capturing energy from sunlight; using the energy to make ATP and to reduce the compound NADP+, an electron carrier, to NADPH; and using the ATP and NADPH to power the synthesis of organic molecules from CO2 in the air. 2. In plants, photosynthesis takes place in chloroplasts: 1. The internal membrane of chloroplasts, called the thylakoid membrane, is a continuous phospholipid bilayer organized into flattened sacs that are found stacked on one another in columns called grana.

Algae Photosynthesis Lab Report Research Question: How would light intensity affect photosynthesis on marine algae N. Oculata? Null Hypothesis: Light intensity will not affect the rate of photosynthesis in marine algae N. Oculata. #1 Alternative Hypothesis: If light intensity increases then the rate of photosynthesis will increase in marine algae N. Oculata. #2 Alternative Hypothesis: If light intensity increases then the rate of photosynthesis will decrease in marine algae N. Oculata. Independent Variable: Light Intensity Experimental Group: (100 watt bulb) (20 cm, 40 cm, 60 cm) Control Group: There is not control group, because there isn?t a part being tested with no light intensity Dependent Variable: The amount of dissolved oxygen Constants:

Chapter 25: The Origin and Diversification of Eukaryotes Overview: Shape Changers Because eukaryotes have internal membranes, they can perform a wide variety of tasks that prokaryotes are unable to perform. An example is a Didinium eating a larger Paramecium The cytoskeleton allows the Didinium to change its shape enough to engulf the Paramecium Concept 25.1 Eukaryotes arose by endosymbiosis more than 1.8 billion years ago Endosymbiosis in Eukaryotic Evolution There is now considerable evidence that much protist diversity has its origins in endosymbiosis Endosymbiosis is the process in which a unicellular organism engulfs another cell, which becomes an endosymbiont and then organelle in the host cell Mitochondria evolved by endosymbiosis of an aerobic prokaryote

Overview: The Process That Feeds the Biosphere ? Photosynthesis is the process that converts solar energy into chemical energy. ? Directly or indirectly, photosynthesis nourishes almost the entire living world. ? Autotrophs sustain themselves without eating anything derived from other organisms. ? Autotrophs are the producers of the biosphere, producing organic molecules from CO2 and other inorganic molecules. ? Almost all plants are photoautotrophs, using the energy of sunlight to make organic molecules from water and carbon dioxide. ? Photosynthesis occurs in plants, algae, certain other protists, and some prokaryotes. ? These organisms feed not only themselves but also the entire living world. ? Heterotrophs obtain their organic material from other organisms.
