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.
