Final answer:

True. Axonemes have a "9 + 2 array" of microtubules, where nine microtubule doublets surround a central pair of single microtubules in cilia and flagella.

Step-by-step explanation:

The statement 'An axoneme is an array where nine pairs of microtubules are wrapped around a core pair of microtubules' is True. The axoneme of cilia and flagella features a characteristic structural arrangement known as the "9 + 2 array." This means that inside cilia and flagella, there exists a pattern where nine pairs of microtubules, referred to as microtubule doublets, encircle two central microtubules, also termed singlets. Thus, each axoneme comprises a ring of nine outer doublet microtubules surrounding a central pair of single microtubules.
