Calvin cycle

Photosynthesis Converts solar energy into chemical energy Utilizes that to make ATP Generates O2 and organic molecules which are used in cellular respiration Energy Flow and chemical recycling in ecosystems Plant cell Have mitochondria Undergo cellular respiration Concept 10.1 Chloroplasts Site of photosynthesis Chlorophyll- pigment that absorbs light energy Thylakoids- contain chlorophyll Stomata Pores- can open and close By closing pores water won?t evaporate as quickly and CO2 can?t enter so sugars are made so won? Permits gas exchange CO2 enters O2 exits Found on underside of leaf Lights reactions Allow cell to make ATP Occur in thylakoids Split H2O Release O2 Produce ATP and NADPH+H+ ATP utilized to make sugars Calvin Cycle Energy requiring process

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.

Mica Piro Chapter 10: Photosynthesis The Process That Feeds the Biosphere The conversion of light energy from the sun to chemical energy stored as sugar is called photosynthesis (occurs in algae, certain other unicellular eukaryotes, and some prokaryotes) Nourishes almost the entire living world directly or indirectly Organism acquires the organic compounds it uses for energy and carbon skeletons by one of 2 major modes: autotrophic nutrition or heterotrophic nutrition Autotrophs (?self-feeders?) sustain themselves without eating anything derived from other living beings Produce their organic molecules from CO2 and other inorganic raw materials obtained from the environment

Chapter 10: Photosynthesis ?Photosynthesis is the process that converts solar energy into chemical energy ?Directly or indirectly, photosynthesis nourishes almost the entire living world This chapter is as challenging as the one you just finished on cellular respiration. However, conceptually, it is a little easier because the concepts learned in Chapter 9: Chemiosmosis, and an electron transport system play a central role in photosynthesis. 1. As a review, define the terms autotroph and heterotroph. Keep in mind that plants have mitochondria and chloroplasts and do both cellular respiration and photosynthesis.

Chapter 10 Photosynthesis Overview: The Process That Feeds the Biosphere Photosynthesis Is the process that converts solar energy into chemical energy Plants and other autotrophs Are the producers of the biosphere Plants are photoautotrophs They use the energy of sunlight to make organic molecules from water and carbon dioxide Figure 10.1 Photosynthesis Occurs in plants, algae, certain other protists, and some prokaryotes These organisms use light energy to drive the synthesis of organic molecules from carbon dioxide and (in most cases) water. They feed not only themselves, but the entire living world. (a) On land, plants are the predominant producers of food. In aquatic environments, photosynthetic organisms include (b) multicellular algae, such

MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. Use the following information to answer the questions below. Thomas Engelmann illuminated a filament of algae with light that passed through a prism, thus exposing different segments of algae to different wavelengths of light. He added aerobic bacteria and then noted in which areas the bacteria congregated. He noted that the largest groups were found in the areas illuminated by the red and blue light. 1) What did he conclude about the congregation of bacteria in the red and blue areas? A) Bacteria are attracted to red and blue light and thus these wavelengths are more reactive than other wavelengths.
