7 . The major difference between the Agar material and the Mica material is that the Agar material is premeable and the Mica is not permiable(impermiable).

8. Theexperimentdescribedinthe ReadThis! B ox supportstheideathathormonesare involved in phototrophic response by showing that when the permiable Agar is placed the phototrophism still occurs because the light reacts to the light sensory nerves of the plant therefore making it release auxin towards the light stimulus.

The Role of Hormones in Plants The majority of people know that hormones play a vital and important part in animal growth and development.

    SECTION 1 HORMONES Hormones are chemicals released by cells that affect cells in other parts of the body. Only a small amount of hormone is required to alter cell metabolism. It is essentially a chemical messenger that transports a signal from one cell to another. All multicellular organisms produce hormones; plant hormones are also called phytohormones. Hormones in animals are often transported in the blood. Cells respond to a hormone when they express a specific receptor for that hormone. The hormone binds to the receptor protein, resulting in the activation of a signal transduction mechan

Similar to a giant vacuum cleaner, the plant will consume hundreds of millions of litres from the ocean and put it through a process known as reverse osmosis; it works by forcing the water through a membrane, which lets clean water through but stops salts, viruses and microorganisms, therefore turning the salty liquid into drinking water. Desalination is an energy-intensive process and the proposed plan

There is something about Superheroes that appeals to small children, and human nature in general. Maybe its the desire to be special that
