Question

Many researchers think that the first eukaryotic cells obtained energy for life-sustaining functions from organic compounds. Given this information, which of the following organelles most likely appeared last in eukaryotic cells?
a.plasma membrane
b.chloroplast
c.ribosome
d.nucleus

Answer 1

Answer: Chloroplast

Explanation:

The presence of chloroplast would have been the last organelle which appeared in the eukaryotic cell. Chloroplast helps in photosynthesis which means prepare food from the inorganic compounds.

But here the cell obtains energy from the organic compounds which states that there is no need of chloroplast in the cell as they obtain energy by hetero tropic mode of nutrition.

Hence, chloroplast is the correct answer.
