Question

question 5
which of the following organelles is the distinguishing feature of eukaryotic cells?
golgi apparatus
vacuole
nucleus
endoplasmic reticulum

Explanation:

Eukaryotic cells are defined by having a membrane - bound nucleus. Prokaryotic cells lack a true nucleus. While Golgi apparatus, vacuole, and endoplasmic reticulum are present in eukaryotic cells, they are not the distinguishing feature. The nucleus, with its nuclear membrane, is the key feature that sets eukaryotic cells apart from prokaryotic cells.

Answer:

nucleus
