Farmers should discontinue the use of Bt corn (genetically modified maize)as their negative affects on the health of the consumers have not been fully over ruled by the recent research. In my opinion, genetically modified crops, although, are resistant to various pests, should not be encouraged because of the toxic chemical contents used during their production. There's a strong likelihood of these toxic chemicals entering our food chain and also being harmful to other naturally growing plants, hence there's a need for more research before this idea is pursued.

Describe the procedure of water reaching the leaves from the roots of a plant

Lisa [10]

The water enters the xylem first by osmosis. Water moves from the soil to the root hair cell down a water potential gradient, and to the root cortex cell from a higher water potential to a lower water potential, this process will be repeated until water enters xylem. Because transpiration is occurring in the leaf, water is lost so there is a lower water potential inside the leaf. Osmosis moves water from the xylem to the leaf because the xylem has a higher water potential. Water moves from the xylem to the cells of the leaf. This pulls water up the xylem via cohesion which is the process of water molecules attracting each other and sticking together. Water does not fall down the xylem as here is adhesion which is the process of water molecules sticking to the inside of the xylem.
