Im doing a project for advanced higher biology and its due in tomorrow first thing! Only I just realised that I have not finished my introduction. It needs to be about two pages long. It consists of background information. My project is investigating the effect of age and temperature on the volume of juice produce by apples. I have already covered Anti-cancer and Antioxident properties of natural chemicals in apples and the storage of apples but that only covers one page and I dont know what else to write about. Does anyone have any suggestions about what to write about apples that is relevent. Your help will be greatly appreciated.

Talk about cider production.

temperature increases enzyme activity, breaks down pectin and cellulose in apple skin and cell walls, releasing juice, therefore more juice released when incubated at higher temperatures (eg if test tube of apple pulp plus enzyme solution put in a water bath set at different temperatures, you can then leave it in the bath for say 30 mins, take it out and pour the pulp through a filter, and see how much juice is produced in a certain time. amount will increase with temperature up to about 45 degrees C, after which enzymes will denature)
as apple gets older the cell walls break down, and so like with temperature, more juice produced.
you could draw diagram of cellulose cell wall with pectin etc.

Pick out some interesting facts from these sites:

Such as: apple seeds contain cyanide but not enough to be harmful.
It takes 36 apples to make one gallon of cider
The largest apple ever picked weighed 3 pounds.
Fresh apples float in water because they are 25% air.

Maybe the different kinds of apples and how they have been genetically enhanced over the last couple of hundred years.

Instant "fast food" What could be simpler - wash under the tap and ready to eat! Anywhere, anyhow, anytime try them cooked, stuffed with sweet mincemeat & chopped nuts mmmmmmmmmmmmmmmm...........................................no need for custard. Dont forget to to eat everything even the core & pips are good for you. Mini hugs!
