Ch. 10 Notes Photosynthesis significance: organic substances created Autotrophs have photosynthesis Chemosynthetic organisms are bacteria These organisms build their own organic compounds Know trophic system Summary equation: 6(H2O) + 6(CO2) -----> C6H12O6 Know if endergonic or exergonic Source of energy is light Light is electromagnetic: both matter and energy When light strike anything they release energy This means that the energy is less after Release heat Night vision uses heat If the part of the plant is green then it is involved in food producing. Bigger the leaf the more water is accessible More surface area meaning easier loss of water Cells forming skin of the leaf are clear This is why we can see the green Plants are at brutal war with getting light and water

Virtual Lab Journal Response Sheet Date: 11th Feb 2015 Name of Virtual Lab: Energy in a cell Please include the questions. This can be done by highlighting, copying and pasting into the corresponding space What is the importance of the light and dark reactions in photosynthesis? Light Dependent Reaction is the initial stage of Photosynthesis where solar energy is converted into potential energy, the light Dependent Reaction produces oxygen gas and converts ADP and NADP+ into ATP and NADPH .Dark Reaction takes place in Stroma of the chloroplasts in photosynthetic plants, Energy from light are stored has ATP and NADPH .in Calvin cycle this stored energy is used to make sugar molecule, the Calvin cycle is a complex theory of chemical reactions carried out in stroma.

Ch 10: Photosynthesis 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 (fixing carbon) Almost all plants are photoautotrophs, using the energy of sunlight to make organic molecules Photosynthesis occurs in plants, algae, certain other protists, and some prokaryotes Heterotrophs obtain their organic material from other organisms Heterotrophs are the consumers of the biosphere

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.

Photosynthesis Wednesday, March 06, 2013 11:00 PM ? Photosynthesis Photosynthesis - the process of converting energy in sunlight to energy in chemical bonds, especially glucose 6CO2 + 6H2O + light -> C6H12O6 + 6O2 Begins with light-absorbing pigments in plant cells A pigment molecule is able to absorb energy from light only within a narrow range of wavelengths In order to absorb as much of the entire bandwidth from sunlight as possible, different pigments, capable of absorbing different wavelengths, act together to optimize energy absorption These pigments include the green chlorophyll a and chlorophyll b and the carotenoids, which are red, orange, or yellow
