Exploring Our Land
Duration : 20:57 Year : 1988 Code No.634
This programme brings home to the viewers the wealth of richness from rocks, minerals, soil, forest, water and other resources. One of the earliest programmes produced by EMRC, EXPLORING OUR LAND sensitises the viewer so that nature is taken care of rather than plundered. As nature affects us we affect nature as well.
Plant Fossils - 1: Nature's Own Museum
Duration : 25:34 Year : 1990 Code No.682
This is a very useful series of 5 programmes dealing with Plant Fossils. The discovery of plant fossils has led to some startling conclusions about the evolution of life on earth. Plants have multiplied and diversified over millions of years from the Precambrian era onwards. Scientists have found fossil evidence to support the diversification sequence. Plants have been preserved by Nature in many different ways. Some of these methods are recreated in the laboratory.
Plant Fossils - 2: A Study Of Nature's Museum
Duration : 16:00 Year : 1990 Code No.287
Plant fossils reveal the entire history of plant evolution. For this, they have to be carefully studied and analysed. This part of the series demonstrates some of the laboratory techniques, which undergraduate students should know, such as maceration, the peel technique and the thin section technique.
Plant Fossils - 3: The Evolution From Algae To Angiosperms
Duration : 16:58 Year : 1990 Code No.294
Through a study of plant fossils we learn about the evolution of plants, right from the earliest algae, to the present day angiosperm. In this part, we briefly examine the different features of land plants, which have evolved over time - such as roots, leaves, spores and pollen grains.
Plant Fossils – 4: Biospheres Of The Past
Duration : 13:44 Year : 1990 Code No.296
The biosphere of any ecosystem is continuously changing. The plant fossil is one of the major indicators of these changes. For example, the biosphere around Calcutta is very different from what it was 6,500 years ago. Plant and animal fossils that were discovered in and around Calcutta indicate that this entire area was once under the sea.
Plant Fossil - 5: The Moving Biospheres Of The Moving Continents
Duration : 16:53 Year :1990 Code No.297
There have been many changes in the geological history of our planet. Much of the information about the movements of the continents and their biospheres comes from plant fossils. Some of the major indicators of the changes are coal, petroleum, stromatolities and angiosperm plants.
