Light affects euglena by inhibiting growth. Specifically light inhibits glucose consumption and growth on glucose containing mediums. The permeability of the cellular membrane being modified is a possible explanation.

What is the light sensing organ in Euglena?
actually there is eye spot in Euglena which help it in the detection of light
Why is a sensory structure so important to the euglena?
Euglena have a primitive organelle called the eyespot which detects light.
Light sensitivity in euglena is provided by the eyespot True or False?
Yes, light sensitivity in euglena is provided by the eyespot.
How does Euglena react to light?
it moves towards the light
What does the eyspot do?
help the euglena find light.
Euglena's survival in the light structures?
will pwns
What is the eye spot for on a euglena?
to sense light
What helps euglena detect light?
eyespot
What structure do euglena have that is sensetive to light?
Euglena use an eyespot to detect light. An eyespot is a dark spot on their body. They cannot see the world around them but they can see light. The eyespot is located anywhere on their body but usually near their flagella. A flagella is a whip-like strand that euglena and other organisms use to move through the water. Euglena are producers and they make food through photosynthesis so they need the light.
How do the eye spot and chloroplasts work together to help the euglena survive?
"The eye spot is a photo receptor. It alerts the Euglena to the presence of light. The chloroplast uses light to carry on photosynthesis. While the Euglena is in the presence of light it is making food. The Euglena also can eat food like other Protists if there is no light." quoted by ATP-Man (http://answers.yahoo.com/question/index?qid=20080114172048AAK4szq)
What is the significance of an eyespot in the cell of Euglena?
To detect light
Why does euglena like red light?
because it absoreds red light hahaha
