conducted to test the above mentioned hypothesis by using the materials such as two pots‚ soil‚ mustard seeds‚ heliotropic chamber or card board box with a hole on one side‚ and water. Procedure of the experiment: Two pots are prepared by filling them with soil‚ and are labelled as A and B. A few (2-3) mustard seeds are sown in each of them. The conditions necessary for germination of seeds such as oxygen‚ moisture (water)‚ and optimum temperature are provided in order to allow them to germinate

Five hundred million years ago‚ the invasion of land was under way. Why then? Astronomical numbers of photosynthetic cells had come and gone‚ and oxygen-producing types had changed the atmosphere. High above Earth‚ the sun’s energy had converted much of the oxygen into a dense ozone layer‚ a shield against lethal doses of ultraviolet radiation. Until then‚ life had not ventured above the surface of water and mud. Algae were evolving at the water’s edge‚ and one group – probably the charophytes

Groundnut seeds are a nutritional source of vitamin E‚ niacin‚ falacin‚ calcium‚ phosphorus‚ magnesium‚ zinc‚ iron‚ riboflavin‚ thiamine and potassium. Groundnut kernels are consumed directly as raw‚ roasted or boiled kernels or oil extracted from the kernel is used as culinary oil).

Substantial Content I. Importance of natural method of pest control The problem with broad range conventional pesticides is that they not only kill the bad bugs‚ but they rub out the good bugs‚ too. A garden without natural predators means a world of insects gone wild. There’s nothing left to keep pest levels in check. In fact‚ chemicals can mean double trouble because although you wipe out the first wave of pests‚ the second wave which is not the usual pest‚ but another insect moving into the

Further‚ it was difficult to germinate the seeds‚ which lacks any functional endosperm. The seeds sown in the nursery beds required long period of germination and any disturbance to the soil or physical environment destroyed the whole population. Orchids from 9% of our flora and are the largest botanical family of higher plants in India

of Easter Island. You make an interesting and valid point. Ignorance is what led the Easter Islanders to the demise of their region. Overuse of the natural habitat‚ coupled with the issues of attempting to plant seeds for the trees to grow‚ yet being attacked by rats before the germination process was detrimental. Part of me also thinks about the massive statues they made and the wasted resources it took to move them.
