Therefore within this report my major aspect is Sarracenia and my minor will be my visit to Kew.

Middle

* Zone 4 This is the last zone in most species of the Sarracenia. It is situated in the base of the pitcher tube, containing digestive enzymes, which help to digest the prey to give the pitcher its nutrients, and downward pointing hairs making escape impossible. * Zone 5: The base of the tube This is only found in the Sarracenia purpurea. It's smooth, has no hairs, very few glands so no absorption takes place here. No one has yet found out its function to the plant. Flowers The flowers of the pitcher plant are found on long stems above the pitcher trap, to avoid trapping the pollinators. They are produced in early spring with a diameter of 3-10cm depending on the species. It has a complicated design, which prevents self-pollination. The whole plant is held upside down, so it can catch the pollen, which may have fallen from the anthers. Their main pollinators are bees. To enter the chamber where the pollen is stored they must make their way past one of the stigmas. In here they will come into contact with a lot of pollen, which will be used to pollinate other Sarracenia.

Conclusion

In ABG's case they take their findings and sharing their results with other conservation groups. 'When nurseries are able to get large numbers of native plants from commercial tissue culture labs, they are less likely to sell plants that have been taken out of the wild.' Some of the rare plants that are grown in tissue culture will be planted in their native habitats. Others will be given to universities and conservational institutes for further study and research. The ethical issues against tissue culture is that it is a form of cloning, so therefore the plant would loose the individual uniqueness, the possible effects on the whole plant family they would all be the same, no variety. Economic It has been found that the digestive enzymes in the carnivorous plants, Nepenthes alata, can be used for antibacterial products. The scientists found seven different proteins within the fluid, of which three were digestive and the other four, were believed to be preservatives against fungi and bacterial infections from other plants. If this is true and found to have no bad effects upon humans it will become a good source of income, as many people around the world want to be clear of infections and remain healthy. . 1This is taken from wikipedia, so is therefore a secondary source, however is fairly reliable. ?? ?? ?? ??
