Which of the following is a similarity between cilia and flagella?
A
Both are composed of cellulose.
B
Both are found only in prokaryotic cells.
C
Both are used for photosynthesis.
D
Both are involved in cell movement.
Verified step by step guidance1
Begin by understanding the structure and function of cilia and flagella. Both are hair-like structures that extend from the surface of many eukaryotic cells.
Recognize that both cilia and flagella are composed of microtubules, not cellulose. Microtubules are part of the cytoskeleton and are made of tubulin proteins.
Identify the primary function of cilia and flagella. Both structures are involved in cell movement. Cilia move fluid, mucus, or cells over their surface, while flagella propel cells through liquid environments.
Note that cilia and flagella are not exclusive to prokaryotic cells. They are primarily found in eukaryotic cells, although flagella can be found in some prokaryotes, like bacteria.
Understand that neither cilia nor flagella are used for photosynthesis. Photosynthesis is a process that occurs in chloroplasts within plant cells and some protists.
