Figure 1.14 illustrates the 'unity underlying the diversity of life' through the architecture and function of cilia. Which of the following statements accurately describes the information presented?
A: Cilia in Paramecium and human windpipe cells differ in their fundamental tubule structure but serve similar functions.
B: The primary function of cilia in both Paramecium and human windpipe cells is to move water or mucus across cell surfaces.
C: Despite differences in organism type and specific function, cilia in both Paramecium and human windpipe cells share a common elaborate system of tubules, suggesting evolutionary unity.
D: The cross-section image shows that cilia are exclusive to single-celled organisms like Paramecium, proving their role primarily in locomotion.
Explanation
Figure 1.14 and its accompanying text explicitly state that cilia in diverse eukaryotes like Paramecium and humans 'share a common architecture... an elaborate system of tubules', demonstrating unity despite functional differences locomotion vs. sweeping .
