What is known as the blind spot of the eye?
The blind spot of the eye is an area on the retina where the optic nerve exits the eye. This spot lacks light-detecting cells, so light that falls on this area cannot be detected. The brain fills in the missing information from the blind spot, so we typically do not perceive a gap in our vision.

Blind spot of the eye contains?
The "blind spot" in all mammals is the tiny area on the retina (light-sensing surface inside the eye) where the optic nerve exits the eye, carrying the optical signals to the brain. It is "blind" because there are no photoreceptors on this tiny area of the retina. In humans, the blind spot in the right eye is about 20 degrees directly to the right of that eye's central vision. In the left eye it is about 20 degrees to the left of that eye's central vision. Thus, normally the opposite eye sees what is in the other eye's blind spot and the brain fills in the missing information. Here is a simple way to demonstrate the blind spot. (I apologize for the ... between the X and W, but formatting is limited here.) To demo the blind spot in your right eye, keep your left eye closed and look directly at the "X" with your right eye. Now move closer or farther from the screen. At about a foot from the screen the W will "disappear" in your peripheral vision (if you look toward the W, it will reappear). To repeat this for your left eye, close your right eye and stare at the "W" as you move closer or farther from the screen. Again, at about a foot away, the X will disappear.X .....................................................................................W
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)
