Statement I: Chameleon changes its skin colour to match with the colour of the surroundings
Statement II: The skin of chameleon emits light of the colour of the surrounding through fluorescence
Statement Analysis: Chameleon Skin Colour
Statement I: Colour Matching
Statement I asserts that chameleons change their skin colour to match their surroundings. This statement is true. Chameleons use colour change primarily for camouflage, helping them blend into their environment to avoid predators and stalk prey. Other factors like temperature and social signals also influence their colour.
Statement II: Fluorescence Mechanism
Statement II claims that chameleon skin emits light via fluorescence to match the surroundings. This statement is false. The actual mechanism involves specialized skin cells called chromatophores containing pigments. Structural changes within the skin also play a role by altering light reflection. Fluorescence is not the biological process responsible for this colour change.
Conclusion
Based on the analysis:
- Statement I is true.
- Statement II is false.
Therefore, the correct conclusion is that Statement I is true, but Statement II is false.
