today’s discussion we talked about Phyllanthus plant that opens up its leaves during the sunrise time and closes its leaf around the sunset time showing a sleep-wake pattern like humans are active during the day and sleep during the night where the opening of the leaf is indicating awakeness and closing of the leaf is showing sleep of the plant and hence the word sleep-wake cycle and this cycle is repeated every day so we started comparing the sleep-wake pattern of a plant from different parts of the country because the sunrise and sunset time would be varied in various parts of the country so is it that this particular time that the leaf is closing or opening or is it due to sunrise or sunset then we talked about the internal clock is there any internal clock within the plant that is making the plant open or closed the leaf during a definite time or light is playing any role This internal clock could be independent of the sunlight
can we build any hypothesis and can we design an experiment based on our hypothesis finding out is light playing a role or is it such that the plant is opening up for 12 hours and closing for 12 hours
we also discussed fruit flies. Whereby can we identify the fly, clearly by looking at some of the features All of us know it is an animal it belongs to kingdom Animalia. It belongs to Phylum Arthropoda [segmented body, bilateral symmetry-the left and right sides of an arthropod are the same – it will have the same number and arrangement of legs, eyes, etc. on the right side of its body as on the left.] (simple example butterfly, lobster, bee, cockroach). It belongs to class Insecta [Insects have three main body segments: the head, thorax and abdomen. They have six legs, one or two pairs of wings] (simple examples cockroach, butterfly, fruit fly, house fly, mosquito). It belongs to the order Diptera [ having two wings] (example s housefly and mosquito). classification could be done by clicking a photograph of the fly or viewing it, of course, We should not only look at the features of the fruit fly but also compare it with other organisms to say whether they belong to this family /order so this can be done at home next comes the family level. One of the short term objectives is to find Drosophila melanogaster from the native so for identifying the fly belonging to Drosophilidae family the wing patterns is to seen so the fly needs to be still the wing is to be magnified so usually when there was no lockdown we had access to the Labs /equipment like microscope were used to magnify the wings of the fly these equipment are not available at home, The idea was to develop our phone camera as a substitute for microscope can we get a good photograph and identify the fly.
Aswathy and Siddhi have already tried some method for magnifying the wing of the fly Sidhhi tried using the torchlight with a transparent sheet on top of the torch and then placing the wing On It and click photography Aswathy has tried several methods that include the torchlight with 2 sheets of white paper and a transparent sheet with the wing only magnification is not enough to get a good picture resolution is important to get a clear image so that we can zoom the picture and see the pattern on the wing to identify the family of the fly
