Which of the following is NOT a functionally analogous pair?Group of answer choicesmitochondria - prokaryotic plasma membranenucleus -nucleiod regionchloroplasts - thylakoidscilia - pili9+2 flagella - bacterial flagella

The pair that is NOT functionally analogous is "mitochondria - prokaryotic plasma membrane".

Here's why:

1. Mitochondria are organelles in eukaryotic cells that produce energy (ATP) through cellular respiration. They have their own DNA and are often referred to as the "powerhouse of the cell".

2. Prokaryotic plasma membrane, on the other hand, is the semi-permeable membrane of prokaryotic cells that separates the interior of the cell from its environment. It controls the movement of substances in and out of cells and protects the cell from its surroundings.

While both are important components of cells, they do not perform the same function, making them not functionally analogous.

The other pairs listed (nucleus - nucleoid region, chloroplasts - thylakoids, cilia - pili, 9+2 flagella - bacterial flagella) are functionally analogous because they perform similar roles in different types of cells or within the same cell.
