Question

Quizplus · Accepted Answer

Nutrient absorption is primarily mediated by the cell membrane in both prokaryotes and eukaryotes. The cell membrane is a selectively permeable barrier that allows certain molecules to enter or leave the cell. Prokaryotes lack internal membranes, such as the nuclear membrane and endoplasmic reticulum, which are involved in nutrient absorption in eukaryotes. The cell wall and peptidoglycan layer provide structural support to the bacterial cell but are not directly involved in nutrient absorption. Proteins in the periplasmic space are involved in the transport of certain molecules into the cell but are not the main mediators of nutrient absorption.
