Question

______________ are hollow tube-like structures that hold some archaeal daughter cells together after cell division while ____________ are grappling hook-like structures that appear to attach archaeal cells to surfaces.

1) Pili; hami
2) Cannulae; hami
3) Hami; fimbriae
4) Cannulae; pili

Answer 1

Cannulae are tube-like structures for archaeal cell connection, and hami are hook-like structures for surface attachment, thus the answer is 2) Cannulae; hami.

Step-by-step explanation:

Cannulae are hollow tube-like structures that hold some archaeal daughter cells together after cell division while hami are grappling hook-like structures that appear to attach archaeal cells to surfaces. Therefore, the correct answer is 2) Cannulae; hami. In the context of prokaryotic cells, both bacteria and archaea have unique surface structures that allow interaction with their environment.

Structures such as fimbriae and pili are common in bacteria, serving purposes like adherence to surfaces and genetic exchange. Cannulae and hami are specific to certain archaeal species, providing similar but distinct functions in cell attachment and community formation.
