What is the light sensing organ in Euglena?
actually there is eye spot in Euglena which help it in the detection of light
Light sensitivity in euglena is provided by the eyespot True or False?
Yes, light sensitivity in euglena is provided by the eyespot.
What does the eyespot do for euglena?
The photoreceptive eyespot allows the organism to orient and swim toward light, whichh is helpful for photosysnthesis. Interesting side note: in Euglena, theree is a dark pigment patch just underneath the eyespot. This means that Euglena is detetcing darkness and swimming away from the dark and thereefore inot the light. Without this pigment patch, the eyespot could not function because the cell body is essentially transparent. I'm not sure if this is the same for Chlamydomonas, but I would expetc so.(From: www.gadgetking.com/trends/eyespot+euglena)
