Question

question correctly match the term and definition: flagella. answer small, barrel - shaped structures oriented at right angles to each other; form the bases of cilia motile cellular extensions found in large numbers in some epithelial cells tiny fingerlike projections of the plasma membrane; increase surface area for absorption long, cellular projections that are tail - like and aid in propulsion i dont know yet

Explanation:

To solve this, we recall the definition of flagella. Flagella are long, tail - like cellular projections that help in the movement (propulsion) of the cell. Let's analyze each option:

• The first option describes centrioles (bases of cilia, barrel - shaped, right angles), not flagella.
• The second option describes cilia (motile, many in epithelial cells), not flagella.
• The third option describes microvilli (finger - like, increase surface area), not flagella.
• The fourth option ("Long, cellular projections that are tail - like and aid in propulsion") matches the definition of flagella.

Answer:

The correct option is the one with the description "Long, cellular projections that are tail - like and aid in propulsion" (the fourth option among the non - "I DON'T KNOW YET" choices).
