Cones and rods are the light sensitive cells.a)Trueb)FalseCorrect answer is option 'A'. Can you explain this answer?

Question

Answer

True

Answer

Answer will be true because light-sensitive cells are present in abundance is cones and rod cells. The rods respond to intensity or brightness of light, while the cones respond to colours. The cones make it possible to distinguish between different colours.

Answer

Yes , true cones are light sensitive to bright light and Rods are light sensitive to dim one .

Answer

Cones and Rods: The Light Sensitive Cells

Introduction:
Cones and rods are two types of light-sensitive cells found in the retina of the human eye. These cells play a crucial role in our visual perception and are responsible for converting light into electrical signals that can be interpreted by the brain. While both cones and rods contribute to our vision, they have distinct characteristics and functions.

1. Cones:
- Cones are the light-sensitive cells that are primarily responsible for color vision and visual acuity, which refers to the ability to see fine details.
- They are concentrated in the central region of the retina, known as the fovea, which is responsible for our central vision.
- Cones are less sensitive to low light conditions and require brighter light to function optimally.
- There are three types of cones, each sensitive to different wavelengths of light: red, green, and blue. The combination of signals from these cones allows us to perceive a wide range of colors.
- Cones are densely packed in the fovea, which is why we have the sharpest and most detailed vision when looking directly at an object.

2. Rods:
- Rods are the light-sensitive cells that are responsible for our peripheral vision, which allows us to see objects in our side vision and in dim lighting conditions.
- They are more sensitive to low light levels and are responsible for our ability to see in the dark, as well as in black and white.
- Rods are concentrated in the outer regions of the retina, away from the fovea. This is why our peripheral vision is less detailed than our central vision.
- Unlike cones, rods do not differentiate between different colors and only provide us with shades of gray.
- Rods greatly outnumber cones in the retina, with about 120 million rods compared to only 6 million cones.

Conclusion:
In conclusion, cones and rods are the two types of light-sensitive cells present in the human eye. Cones are responsible for color vision and visual acuity, while rods are involved in peripheral vision and low light conditions. Both types of cells work together to provide us with a complete visual experience.
