Question

Pili and flagella - which is thinner and shorter?

Answer 1

Flagella are longer and fewer in number, while cilia are shorter and more numerous. Both are involved in cell movement and share a common structural arrangement of microtubules. Despite their differences, both flagella and cilia share a common structural arrangement of microtubules called a "9 + 2 array."

Step-by-step explanation:

Flagella and cilia are both hair-like structures found on cells that are involved in movement. Flagella, which are longer and fewer in number, can be found on cells like sperm and Euglena, while cilia, which are shorter and more numerous, are found on cells such as paramecia and the cells lining the fallopian tubes. Despite their differences, both flagella and cilia share a common structural arrangement of microtubules called a "9 + 2 array."
