PHOTOTAXIS today's simple but interesting experimental test



Phototaxis is a kind of taxis or locomotory movement, that occurs when a whole organism moves towards or away from stimulus of light .

Today I tried something interesting , all of us may have idea about the moina and some organisms including crustacean , insects shows phototactic movement ie they move towards or away from the source of light , in our case our model organism moina move towards the source of light to understand this I design simple experiment which demand only the light source and mobile or any device to record and document the experiment .

1 this video is recorded in day time

2 movement of moina from all directions to downward ie towards light source.

3 movement of moina from all directions towards upward ie towards light source.

4 moina following the directions

Hope videos are satisfactory but still suggest any correction
