STEP 1: Chloroplasts trap light energyPhotosynthesis is aprocess in which Plantsuse sunlight energy tomake glucose (sugar).In Latin, “photo”means “Light” and“synthesis” means “tomake”. So,photosynthesis means“To make with light”.PLANT CELLPhotosynthesis occursin the green leaves ofplants in a tinyorganelle called thechloroplast. The mainfunction of thechloroplast is toproduce food(glucose) duringphotosynthesis.Chloroplasts contain the green pigment, chlorophyll. Chlorophyll absorbs most ofthe colors of light and reflects only green light. This is why leaves appear green,because green light is reflected into our eyes.1. What is photosynthesis?2. What does Photosynthesis mean in Latin?3. Where does photosynthesis occur?4. What is the main function of the chloroplast?5. What is the pigment found in the chloroplasts called?6. Why do most leaves appear green?
Step 2 and 3: Inputs and OutputsPlants absorb Water (H2O) throughtheir roots; transport it up their stems,and into their leaves. CarbonDioxide(CO2) is taken in through smallopenings in the leaves called stomata.Much of the carbon dioxide comesfrom living organisms that exhale it,but some also comes from factorysmokestacks and car fumes.During Photosynthesis, plants use theenergy from Sunlight to transformCarbon Dioxide (CO2) from the air andwater (H2O) from the ground into glucose (sugar) and oxygen.The sugar is used by the plant for energy while the oxygen (02) is created as awaste product and is released (excreted) into the air for us to breath.The formula for photosynthesis is:Sunlight Carbon Dioxide Water Glucose (Sugar) Oxygen7. Where does the Water (H2O) come from?8. Where does CO2 enter the Plant?9. Where does the Carbon dioxide (C02) come from?10.What three things need to go into the plant for photosynthesis (Inputs)?
11.What two things are produced during photosynthesis (Outputs)?12.What is the formula for photosynthesis?Step 4: SUGAR EnergyPlants are called PRODUCERS because theyPRODUCE their own food. The glucose made byplants is used by the plant for energy and growth.Plant energy is also used by CONSUMERS. We (andall other animals) also use this glucose by eatingplants.The oxygen produced by plants is released into theair for us to breath. Photosynthesis is essential for alllife on earth, because it provides food and oxygen.1. Why are plants called Producers?2. What is the glucose used for?3. What is the oxygen used for?4.

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.
