Screenshot of whiteboard from Cube Chatshaala discussion,
An excellent start to compare activity pattern of plants and Animals. In the above picture, pink color graph depicts the opening and closing of Phyllanthus plant leaves in a pattern and with respect to the sunrise and sunset time. Blue color depicts the observation graph of circadian rhythm in fruit flies.

i would like to ask everyone! why fruit flies in this picture are arranged on a paper in a particular manner?

1.CHEMICAL CUES THAT GUIDE FEMALE REPRODUCTION IN DROSOPHILA
MELANOGASTER


females select substrates containing acetic acid (Figure 2) for egg-laying, showing egg-laying attraction,
but do not stay on such sites once they have laid the egg, showing positional repulsion. The egg-laying
preference for acetic acid is primarily relayed through gustatory neurons, while positional aversion is
relayed through the olfactory system (Joseph et al. 2009)
2.D. melanogaster are attracted to food containing acetic acid (AA) as an oviposition (egg-laying)
substrate

  • How smart fruit fly is! * It will lay egg in nutritious and safe place and not in place where there is chance of infection. ‘Egg-laying site preference is thus an chemically-driven behavioral strategy that ensures that offspring are reared in safer environments’
