Final answer:
Yes, a saprobe with a cell wall, such as a fungus, does utilize extracellular digestion by secreting enzymes that break down organic material outside the cell before absorbing the nutrients.
Step-by-step explanation:
The statement is True: A saprobe with a cell wall will utilize extracellular digestion. Saprotrophs, such as fungi, are decomposers that feed on dead organic matter by secreting digestive enzymes and digesting it externally. This process allows the fungus to break down large, insoluble molecules into small molecules that can be absorbed. Thus, fungi produce exoenzymes that function outside their cell walls, which is characteristic of extracellular digestion. Since fungal hyphae are adept at nutrient absorption due to their high surface area-to-volume ratios, they can efficiently absorb the nutrients resulting from the breakdown of complex molecules like polysaccharides, proteins, and lipids.
