Photosynthesis and Cell Respiration All cells need_______________ to carry out their functions, such as making ___________ and transporting substances into and out of the cell. http://khenni.files.wordpress.com/2009/04/irrigation- photosynthesis.gif?w=400&h=357 energy proteins
Sources of Energy 1. The process by which a cell captures energy in sunlight and uses it to make food is called ________________. 2. _______________ is an organism that makes its own food. 3. An organism that cannot make its own food and obtains energy from eating other organisms is called ______________. 4._________________ obtain their energy from absorbing nutrients from other organisms. http://www.biology.iupui.edu/biocourses/n100h/images/41ecosys.gif photosynthesis Autotroph heterotroph Fungi
Two stages of Photosynthesis 1. Capture Energy from the Sun a. Most of this process occurs in the _______________. b. ______________ in the chloroplasts absorb the light. c. The photosynthetic pigment in chloroplasts are called _______________. http://yardandgardenrescue.com/wp-content/uploads/2010/09/chloroplast- Google-Search1.jpg chloroplasts Pigments chlorophyll

Cells use the captured energy to produce _______________. b. Cells use ____________ and ______________ as raw materials for this stage. c. Small openings on the underside of the leaf are called the ________________. d. _____________________ enters the plant through the stomata. sugars watercarbon dioxide stomata Carbon dioxide
Two Stages of Photosynthesis Continued www.youtube.com/watch?v=pE82qtKSSH4&feature=relatedwww.youtube.com/watch?v=pE82qtKSSH4&feature=related e. The _____________ and _____________ undergo a series of chemical reactions inside the chloroplasts. f. One product of the chemical reaction is a sugar called glucose that contains ______ carbon atoms and is a type of a __________________. g. The second product is ______________ which exists the leaf through the stomata. h. The photosynthesis equation is ____________________________________________. i. Some sugar molecules are converted to ____________________. watercarbon dioxide 6 carbohydrate oxygen 6CO 2 + 6H 2 O + light → C 6 H 12 O 6 + 6O 2. cellulose
Brain Power: Trace the energy from the sun through a simple food chain.
Cellular Respiration 1. The process by which cells obtain energy from glucose is called _____________________. 2. During the process of respiration, _____________ break down simple food molecules such as ______________ and release the energy that they contain. 3. Cells obtain energy when ______________ molecules are broken down during respiration. cellular respiration cells glucose
Two Stages of Respiration Stage 1 – molecules of glucose are broken down into smaller molecules. This process takes place in the _________________. Oxygen is not involved in this stage and only a small amount of energy is released. cytoplasm
Two Stages of Respiration Continued Stage 2 – the small molecules from Stage 1 are broken down into even smaller molecules in the ____________. Oxygen is involved and a large amount of energy is released. mitochondria
Cellular Respiration 4. The Respiration Equation - ______________________________ 5. Raw materials for respiration are ____________ and __________. 6. During photosynthesis ______________ and _________________ are used to produce glucose and oxygen. 7. During ____________________, glucose and oxygen are used to produce carbon dioxide and water. C 6 H 12 O 6 + 6O 2 ⇒ 6CO 2 + 6H 2 O + ATP glucose oxygen water carbon dioxide cellular respiration
Brain Power Photosynthesis and respiration can be thought of as opposite processes. Explain why cellular respiration adds carbon dioxide to the atmosphere, photosynthesis does not.
