INTRODUCTION Photosynthesis is the process in which plants can convert light energy into chemical energy to fulfill all of the functions of life. Iron and magnesium are nutrients that play an important role in photosynthesis. Deficiency in either of these nutrients will lead to a change in the photosynthetic rate of plants such as Lemma minor (duckweed). Magnesium is a mobile nutrient that affects older plants before it affects younger plants. Iron is a fairly immobile nutrient that causes chlorosis

PLANT EVOLUTION Plant Evolution Colette Andrews Strayer University SCI 115 Dr. David Davies November 24, 2012 Plant Evolution has been around for millions of years. In fact, plants were the first species on earth and the first to live on land (“Plant Evolution”, D. Davies, accessed 11/24/12). For 1500 million year’s photosynthetic organisms remained in the sea. This is because, in the absence of a protective ozone layer, the land was bathed in lethal levels of UV radiation. Once atmospheric

paleontologists estimate that well over 90 percent of all plant and animal species that ever existed have gone extinct. The Koala is a small marsupial that lives in eucalyptus trees in Australia. These nocturnal (most active at night) animals spend 18 to 20 hours each day resting and sleeping. They are social animals. Koalas are not bears; their closest relative is the wombat. The genus and species of the koala is Phascolarctos cinereus. These herbivores (plant-eaters) eat eucalyptus leaves. Koalas have a

Inquiry Research Paper Every plant is different. There are no two plants that are the same, nor are there two that grow the same way. Some plants grow in hot, dry environments while others grow in cold, damp environments. Some plants grow in the tropical rain forests while others grow in prairies. Even plants that are in the same family can grow in different climates and environments. Plants can be as similar as they are different. Plants need certain factors to be able to thrive in an environment

Edible Oil Mill Machinery technology has undergone a tremendous change ever since beginning of oil milling through various seeds, One of the most important point in the oil milling was the inception of Oilseed Mills. These mills use dry flax seed that doesn't have any fine or coarse impurities. These seeds are generally delivered to the oil mill in bags or baskets, as these are the by-product of the crop, flax fiber. In case the flax seed is not dry, it is dried by simple spreading the seeds on the

Plant Competition INTRODUCTION This experiment was used to show the different types of competition between species. Competition was defined as being a “relationship between members of the same or different species in which individuals are adversely affected by those having the same living requirements, such as food or space” (Competition 2010). There are two different types of competition that we will be observing during this experiment. The first type would be intraspecific, which means “competition

1. What is the title of the news article? 2. Why is boosting crop yields necessary? 3. What enzyme did the researchers target and what does the enzyme do? 4. Why do plants have so much of this enzyme? 5. The Cornell researchers took this enzyme from another source to put into what crop plant? What source did they take the enzyme from? 6. In what way is the substitute enzyme more wasteful than the original enzyme? 7. What is it called when Rubisco uses O2
