PPT-Photosynthesis

Energy and Life Plants and some other types of organisms are able to use light energy from the sun to produce food Autotrophs organisms such as plants which make their own food Heterotrophs. *. Photosynthesis. – process of capturing light . . energy. from the sun to convert water & CO. 2. . . into oxygen and high energy carbohydrates . (food, ex: glucose, starch, & other sugars). Photosynthesis. OB48. Describe, using a word equation, how plants make their own food through photosynthesis.  . OB49. Show that starch is produced by a photosynthesising plant.  . OB50. Investigate the growth response of plants to . Warm up (11-23-15). Explain what you know about plants.. Try to be specific and use scientific terms if possible.. Outline. Objectives. Plant Background Info. Objectives. To gain background information about plants and how they colonized land. Unit 3 . Think back to Energy Transfer…. Living things use energy for . Growth. Repair. Reproduction. Metabolism. The collection of reactions that occur in a cell . Metabolism. Involves either:. . Lauren . Kendle. Winter Ecology. Spring 2012. Background Information. An analysis of 60 species indicated that there were photosynthetic processes in the . bark. Aspen Trees had the highest level of bark chlorophyll . Why Study Photosynthesis?. *All food webs start with photosynthesis!*. Photosynthesis is arguably the most important biological process on earth because of two key chemical reactions. Liberating oxygen:. ENERGY IN THE CELL. ENERGY IN THE CELL. ENERGY CONVERSIONS. PHOTOSYNTHESIS. CELLULAR RESPIRATION. ATP for cell usage. Is about. Starting with. Transformed by. Converted to. Plants & photosynthesis. November 17, 2009. A ___________ is a group of different species that live together in one area.. Community. Population. Organism. Ecosystem. Biome. O. 2 . represents.

We tested the photosynthetic rate of leaf discs of spinach (control) to arugula (experimental) under a 100 watt lamp. Spinach had a higher rate of photosynthesis. Photosynthesis. . converts light energy from the sun into chemical energy in the form of organic compounds through a series of reactions known as . biochemical pathways. . . Autotrophs. . use energy from sunlight or from chemical bonds in inorganic substances to make organic compounds. . Lauren . Kendle. Winter Ecology. Spring 2012. Background Information. An analysis of 60 species indicated that there were photosynthetic processes in the . bark. Aspen Trees had the highest level of bark chlorophyll . Happens in the CHLOROPLAST. Using the chemical - Chloroplast. Only need to learn terms . Thylakoid. Granum. Thylakoid. Little . sacklike. things. Hold the chlorophyll. Like little solar panels. The stacks of Thylakoids are Granum/grana. The light-dependent reaction. The light-independent reaction. Required practical 7: . Use of chromatography to investigate the pigments isolated from leaves of different plants, . eg. , leaves from shade-tolerant and shade-intolerant plants or leaves of different colours.. Autotrophs. – organisms use can make their own food. Some. autotrophs capture light energy from the sun in the process of photosynthesis. Heterotrophs. – obtain energy from the foods they consume.
