Overview of Cone Photoreceptors
Cone photoreceptors are crucial for color vision and function optimally in bright light conditions. They contain pigments that respond to different wavelengths of light.
Analysis of the Statements
- Statement i: *"Give color vision because they contain 3 different pigments."*
This is correct. There are three types of cone cells (S, M, L) that correspond to short, medium, and long wavelengths, allowing for color discrimination.
- Statement ii: *"Pigments are sensitive to red, green, and yellow lights."*
This statement is incorrect. The pigments in cones are not specifically sensitive to yellow; rather, they are sensitive to red, green, and blue light.
- Statement iii: *"Pigments are sensitive to red, green, and blue lights."*
This is correct. The three types of cones are sensitive to these colors, which form the basis of trichromatic color vision.
- Statement iv: *"Individual cone cell contains all three pigments in it."*
This is incorrect. Each type of cone cell contains only one type of pigment, not all three.
Conclusion
Based on the analysis:
- Statements i and iii are correct.
- Statements ii and iv are incorrect.
Thus, the correct answer is option 'a': *only statement i) and iii) are correct*. This understanding of cone photoreceptors is vital in the context of vision and color perception, especially for NEET aspirants.
