Concept:A non-septate hypha is one that lacks cross walls.Explanation:In Rhizopus, the hypha is called non-septate because it has no cross walls dividing it into separate cells. This makes the hypha coenocytic, meaning the cytoplasm is continuous along the length. The absence of chlorophyll (Option A) does not determine septation. Being vacuolated (Option C) is a general cell feature and not the reason. Storing oil globules (Option D) is also unrelated to the presence or absence of cross walls.Answer:B. has no cross wall.
