What is Photosynthesis?
Ad From NewspaperINVENTORS NEEDED!Our city is experiencing environmentalproblems. The streams and rivers inour city are brown from the soileroding into them after it rains. Ourair is brown and hazy from all thesmog and pollution. The buildings andpavements create so much heat in thesummer the temperature is gettinguncomfortably hot. We need your help!We are looking for inventors to comeup with a solution to save our city!
A 6th Grade Student Answered the AdDear City Planners,I have an invention that can solve allyour problems. It can produce freshoxygen, prevent soil erosion, cool thesidewalks, muffle traffic noise, and canlast many years with just a little care. Thisinvention operates on solar power fromthe sun.Along with helping the environment,this invention would provide home for thebirds and other animals. Kids can climb onit and it will make our city more attractive.
Letter continued .This invention can also be made intoother things people can use like paper,houses, baseball bats, or even medicine.When the invention is no longeruseful, it is biodegradable which means itwill break down and become part of theenvironment. It can also be used forfuel.Finally, this invention is not new. Ithas been around for years.Can you guess what this invention is?
A TREE!
Why Study Photosynthesis? Photo means light Synthesis means put togetherPhotosynthesis is how plants put together stuffwith light to make their own foodDirectly or indirectly, all life on Earthdepends on photosynthesis!
Photosynthesis(How do green plants make their own food?) Plants Need– Light from the sun– Water from roots– Carbon dioxide from air,enters plant through tinyopenings in the leaves calledstomata– Chlorophyll: green pigment inplants that trap the sun’senergy to make food
Photosynthesis(How do green plants make their own food?) That energy creates glucose(sugar) and oxygen from thecarbon dioxide and water– The plant keeps the glucoseas food for the plant to help itgrow– The plant releases the oxygeninto the atmosphere

Photosynthesis1. Ingredients:–Sunlight, water, carbondioxide,2. Energy from the sun iscaptured by thechlorophyll andtransforms the originalingredients3. Once the process isdone you have thefinal product: glucose4. Oxygen is releasedSugar Cookies1. Ingredients:–Sugar, butter, flour,eggs, vanilla2. Heat from the oventransforms theoriginal ingredients3. Once the process isdone you have thefinal product: sugarcookies4. Aroma from bakingcookies is released

UNIT 1 PHOTOSYNTHESIS AND RESPIRATION Photosynthesis is the process whereby plants use carbon dioxide, water and light energy in a series of chemical reactions to produce glucose (food). Photosynthesis Microorganisms Interactions and interdependencies Life and living Photosynthesis and respiration Photosynthesis Respiration
photosynthesis of an aquatic plant [Elodea]. The rate of photosynthesis can be determined by measuring the concentration of dissolved oxygen as the plant undergoes photosynthesis. There are multiple methods for measuring the rate of photosynthesis including: The uptake of CO 2 The production and release of O 2
In this live Gr 11 Life Sciences show we take a look at Photosynthesis. In this lesson we study the process of photosynthesis looking at the light and dark phases. We discuss the importance of photosynthesis as well as consider the effects of varying amou nts of light, carbon dioxide and temperature on the rate of photosynthesis.
LAB 8 – Photosynthesis . Objectives. 1. Assess CO 2 consumption and O 2 production during photosynthesis. 2. Analyze the role of light in photosynthesis. 3. Examine the effect of different wavelengths of visible light on photosynthesis. Introduction . In order to , organisms require a source of
of domestic violence in 2003. Tjaden and Thoennes (2000) found in the National Violence Against Women Survey that 25.5% of women and 7.9% of men self-reported having experienced domestic violence at some point in their lives. Unfortunately, only a small percentage of abused men are willing to speak out in fear of ridicule, social isolation, and humiliation (Barber, 2008). Therefore, because of .
