Answer to Problem 37A
Correct answer :
Option (D) reproductive cells.
Explanation of Solution
Explanation/justification for the correct answer :
Option (D) reproductive cells. The reproductive cells of water molds are biflagellate with heterokont flagellation. Flagella helps the reproductive cells in the movement.
Explanation for incorrect answer :
Option (A) nuclei. Water molds are eukaryotic fungi-like protists. So, all of them possess nuclei inside which the genetic material is present that is enveloped by the nuclear membrane. Hence, it is an incorrect answer.
Option (B) plasmodia. They are the characteristic feature of smile molds. Though the water molds possess coenocytic mycelium (multinucleate and aseptate), they are not considered as plasmodia. Hence, it is an incorrect answer.
Option (C) pseudopods. Pseudopods are the false feet like structure that are present in most of the amoeboid forms. Water molds have filamentous structure extending from the main body similar to the hyphae of fungi. Hence, it is an incorrect answer.
