PPT-Background on Maize and Photosynthesis

Corn or Maize Zea mays Typical Corn Growth Typical ear of corn Zea mays subsp mexicana Zea mays subsp mays Teosinte vs Corn Growth Teosinte Corn Steps from Teosinte to Maize. *. 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). Lab. 5: Photosynthesis. Lab. 5: Photosynthesis. Leaves float in water due to presence of air (air spaces) in the leaf. . How does one get them to sink?. Lab. 5: Photosynthesis. Put leaf discs under vacuum . A . s. elf instructional material for smallholder farmers in marginal rainfall areas in Malawi. Next. By . Raphael B. Mkisi. The purpose of this module is to equip smallholder farmers living in marginal rainfall areas with knowledge and skill in maize pit planting as rain water harvesting to reduce the effects of drought.. 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. High. level of animal manure. Hoestaar=2009. . Fsg_Navn=JyMa29. . . . A3= Maize,220 N/ha. A1= Maize,. 100 N/ha. C. 1= Maize + . Ryegrass. ,. 220 N/ha. C1= Maize + . ryegrass. , 100 N/ha. Nitrate . Photosynthesis. . Process. = plant cells use light energy to rearrange water and carbon dioxide molecules into sugar . molecules. Oxygen is a by-product (leftover, waste product). Energy now stored in the sugar. High. level of animal manure. Hoestaar=2009. . Fsg_Navn=JyMa29. . . . A3= Maize,220 N/ha. A1= Maize,. 100 N/ha. C. 1= Maize + . Ryegrass. ,. 220 N/ha. C1= Maize + . ryegrass. , 100 N/ha. Nitrate . It is the mission of the Maize Genetics Executive Committee to identify both the needs and the opportunities for maize genetics, and to communicate this information to the broadest possible life science community. This community includes scientists, funding sources for scientists, and the end users for the accomplishments of maize genetics, from farmers to consumers.. 8-1: Energy & Life. What is energy?. The ability to do work.. What is the difference between autotrophs & heterotrophs?. . Autotrophs = make their own food. . Heterotrophs = can’t make their own food; must eat other organisms. Refer to . pg. . 83-92 . in . Holtzclaw. , . Ch. 10 in Campbell and media resources. . Refer . to . pg. . 297. -299 . in . Holtzclaw. , Lab . Inv. 5 . in . Lab Manual. Try This!. Where does the biomass of a tree primarily come from?. Photosynthesis. - a process used by plants and other autotrophs to convert the light energy captured from the sun into chemical energy that can be used to fuel the organism’s activities. . *It is the way plants make food! . 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.
