Genetically Modified Foods (GM Foods) Project
Transcript of Genetically Modified Foods (GM Foods) Project
;) Activity 1 Make a list of foods that are already in our supermarkets. Activity 2 Trace the development of a common food-crop from its original state to its modern and GM forms Activity 3 Show how
GM plants and animals could affect
the biological diversity of particular
environments Try to find out where GM foods are being grown and show details on a world map. Activity 5 Who benefits from
GM foods? Rapeseed
Cotton seed oil
Dairy Products Activity 6 What are your thoughts on Gm foods? Psss We think that GM foods will not affect the environment as long as it is kept under control and isolated from other plants and animals with NO side-effects!
BUT... If animals do eat the plants that have come out of the controlled environment, we could have many complaints from farmers saying that their cows have turned blue and their chickens have gone featherless. In Australia, we don't make many
GM foods. But we do Genetically Modify
cotton and canola but not much more! In America, we have the most GM foods out of anybody in the world! We GM maize, soybean, cotton, canola, sugarbeet, alfalfa, papaya and squash! Genetically Modified
.Our Brains This table shows how much of GM Crop has been planted in different parts of the world Activity 4 In Europe, we don't have many GM foods grown here. But we do GM maize and potato though! In Africa, we have a reasonable amount of GM foods. We GM maize, soybean and cotton! In China, We have the second most GM foods. We have 1 less GM crop than America! But we GM a crop that no other place in the world does. We GM maize, cotton, papaya, poplars, tomatoes and sweet peppers. Guess which crop no one else in the world GM. A: Sweet Peppers! GM foods have rea GM foods have a massive beneficial effect on
supermarkets because most of them are GM to have longer shelf life so they can last longer on shelves which keep the stocks high which means more money because Super Markets (that don't use GM foods) have to keep throwing out bad fruit and veges which means money wasted. EXCEPT with farmers, this is bad because with super-markets using GM food with longer shelf life, super-markets don't have to buy as much fruit and veges because they don't have to keep disposing a lot of food out. AKA:
GOOD FOR SUPER-MARKETS
BAD FOR FARMERS! w We think that GM foods are very beneficial and helpful because they help produce more quantity and more food. This makes food cheaper because they're easier to farm and makes more quantity. And further more, most foods are GM to have longer shelf life which means you don't have to throw them out after a week! They make the food have more food inside like by making the seed smaller. Both of these things make the food a lot better value for money. We think that GM foods are terrific and extremely beneficial to everybody. Now, for our
QUESTIONS! Question 1 How do cells work and
reproduce? Question 2 What do genes do? Question 3 What processes are used to genetically modify plants and animals? Question 4 What GM foods are already available? Question 5 What are the benefits of GM food-crops
and animals? Question 6 What risks do GM food-crops and animals pose? AND LAST ONE THANK YOU FOR WATCHING...
HOPE YOU IT THANK YOU FOR WATCHING!
HOPE YOU IT Cells reproduce by splitting themselves in two, which is called a binary fission. There are two ways of splitting apart and reproducing, metosis and meosis. The cell's organells, lysosomes, mitochondria, and cytoplasm make a cell work. With these elements the cells are able to eat, drink, run, lift and more. Your genes are traits that were inherited from your parents. Half your genes came from your mother and half from your father. Genes tell your body how to make all its proteins. Like we answered in activity 1 - Like we said in Act 1 -
Flax seed oil
Dairy Products Genetically modified foods and animals benefit us by increasing the amount of food crops, efficiency of growing food crops, protecting the food from harmful pests like bugs, fighting the weather and reducing the size of seeds and increasing the amount of edible foods. The process of GM food is taking DNA from a living organism and putting it into a different organism to create something completely different. E.g: Taking DNA from flounder (because flounder can with stand very low temperatures) and putting that DNA from the flounder and putting it into the tomato correctly will give the tomato the power to with stand the same temperatures as a flounder can! Also, GM foods have amazing beneficial "super-powers")
-Nutrition benefits PROS
•Cost effective because it is designed to resist pests and produce good crops under poor climate conditions. E.g. In Africa where there is constant drought they can produce crops which would normally die.
•Because they are pest resistant it reduces the need for additional chemicals, pesticides and other dangerous drugs.
•They may help reduce world hunger as crops are altered to grow faster and feed more people. They can also contain additional nutrients such as calcium and iron which would not be available to poorer countries. CONS
•The technique is too new for scientists to work out how it affects our bodies.
•Modifying food may alter how it interacts with humans.
•Poor countries will only have access to this type of food if given to them, which means that rich countries will control the food. This has the effect that poor countries become to rely on rich countries which in the end will harm the poor countries economic growth. GM foods can, and have caused some really bad side effects. They can make animals have weird deformities and weird colours. One of the weirdest genetically modified animals is the belgian blue cow. It has much more developed muscles and is a lot bigger. EXCEPT with farmers, this is bad because with super-markets using GM foods with longer shelf life, super-markets don’t have to buy as much fruit and veges because super-markets don’t have to keep disposing food that has gone off. Also, GM foods have amazing beneficial “super powers”

Bibliography 75 - 75 By Alex and Justin ;) Please exit out of Prezi and
go to desktop. Look for a
file named, "GM FOODS".
From there, an excel file
comes up. That is our
comparison between normal
food (NOT GM) and GM foods.
