Hi, I just did an experiment on the microorganism Euglena, and I found that as time increased more Euglena move from the dark section of a slid e(With no light) to the section of teh slide with dimlight. Can you explain why more Euglena moved to the light side...
Eg. My results
1st minute to the 2nd minute :
12 Euglena moved from the dark to the light side
2nd minute to the third minute:
16 Euglena moved from the dark to the light side
3rd minute to teh fourth minute:
26 Euglena moved from teh dark to the light side

They have the ability to transform light into sugar (photosynthesis) because they have chloroplasts in their bodies. They also have a light sensitive photoreceptor.

They need light for photosynthesis. They have chlorophyll like a plant, and movement like an animal. It is a protist, however.
