From your knowledge of physiology can you think of some method of increasing the life of cut plants in a vase?

Plants are autotrophic. Can you think of some plants that are partially heterotrophic?

We commonly call ATP as the energy currency of the cell. Can you think of some other energy carries present in a cell? Name any two.

While eating watermelons, all of us wish it was seedless. As a plant physiologist can you suggest any method by which this can be achieved?

Agreat physicist of this century (RA.M. Dirac) loved playing with numerical values of Fundamental constants of nature. This led him to an interesting observation. Dirac found that from the basic constants of atomic physics (c, e, mass of electron, mass of proton) and the gravitational constant G, he could arrive at a number with the dimension of time. Further, it was a very large number, its magnitude being close to the present estimate on the age of the universe (~15 billion years) . From the table of fundamental constants in this book, try to see if you too can construct this number (or any other interesting number you can think of). If its coincidence with the age of the universe were significant, what would this imply for the constancy of fundamental constants ?

Science, like any knowledge, can be put to good or bad use, depending on the user. Given below are some of the applications of science. Formulate your views on whether the particular application is good, bad or something that cannot be so clearly categorised: - Computers for increase in work efficiency
