What does the eyespot enable the protozoa to do?
A red eyespot is clearly visible. In fact the real light sensitive organ is the swelling near the base of the flagellum. The red area makes sure only light from one direction is detected. Since the light sensitive organ is directly connected to the flagellum, Euglena is perfectly able to swim towards a light source
What part of the retina where there are no light sensitive cells?
yellow spot or blind spot. it has no rod or cone photorecepter cells.
Which is a charateristic of a euglena?
Euglena are unicellular organisms, commonly identified by having two flagella and a photoreceptor called and eyespot. Most have chloroplasts, but not all. Euglena's plasma membrane is surrounded by a flexible layer known as the pelicle which can flex to allow for movement.
What does the red eye spot in a cell do?
The red eye spot in a cell allows the cell to sense light so that it can move towards or away from it. The cell can swim by using the flagellum (long string like things on the end of a cell).Hope this helps :)
Why can the spot on the retina that has no rods and cones be called the blind spot?
The blind spot on the retina lacks light-sensitive cells (rods and cones), causing it to be unable to detect light and form images. This creates an area where the brain doesn't receive visual information, making it a literal "blind spot" in our field of vision.
What does euglena use?
A light sensitive area near the base of its flagellum called an eye spot this directs it towards light as a directional response to stimuli. Therefore it can use its chloroplast to photosynthesise.

What happens if light rays are focused directly on the blind spot?
If light rays are focused directly on the blind spot in the eye, those particular light rays would not be detected by the retina because the blind spot is the area on the retina where the optic nerve exits and there are no light-sensitive cells present. This would result in a gap in the visual field where those light rays are not perceived.
What part of the eye isn't sensitive to light?
The part of the eye that isn't sensitive to light is the blind spot, also known as the optic disc. This area is located where the optic nerve exits the eye, and it lacks photoreceptors (rods and cones), meaning it cannot detect light. As a result, any images that fall on this spot cannot be perceived by the brain, creating a gap in the visual field.
What does the red eye spot in a cell do?

Is there such a spot call the g-spot?
There is such a g-spot. it is in the vagina and it is like a little sack that is very sensitive.

What is a Mans most sensitive spot?
The most sensitive spot on a man's body is typically considered to be the tip of the penis, specifically the glans. This area is highly concentrated with nerve endings, making it very sensitive to touch and stimulation.
What ia a yellow spot on the eye?
The yellow spot or the bright spot is a point on the retina which is most sensitive to light radiations. It is probably called so because yellow is the colour to which human eye is most sensitive.
What is a red eye spot in a chlamydomonas?
A red eye spot in Chlamydomonas is a stigma, which is a light-sensitive organelle that helps the organism orient itself towards light for photosynthesis. The red color comes from pigments within the stigma that aid in light absorption.
