Why are anatomy and cytology included for the classification of organisms in modern taxonomy?

Correct answer: To know precise evolutionary relationships and accuracy

Answer: A. Modern taxonomy does not depend only on outward appearance. Anatomy studies the internal structure of an organism, such as organs, tissues, and their arrangement. Cytology studies cells, including their structure and important features. These characteristics are often more stable and informative than superficial features such as colour, size, or body shape. By comparing internal and cellular features, scientists can identify similarities that may reflect common ancestry and can distinguish organisms that look alike but are not closely related. Option B is wrong because external traits are usually visible; the problem is that they may be insufficient. C is wrong because the purpose is accuracy, not difficulty. D is wrong because laboratories are not the biological reason. Memory cue: outer form suggests; internal and cellular evidence confirms.
