Vedclass · Answer

(A) In Pteridophytes,the main plant body is a sporophyte which differentiates into true root,stem,and leaves. These leaves are known as sporophylls when they bear sporangia. Inside these sporangia,spore mother cells undergo meiosis to produce spores. Therefore,statement $S$ is true because spores are produced in sporangia,and statement $R$ is also true because these sporangia are borne on specialized leaves called sporophylls. Since the production of spores in sporangia is directly facilitated by their location on sporophylls,$R$ is the correct explanation of $S$.

Statement $S$: In Pteridophytes,spores are produced in sporangia. Statement $R$: In Pteridophytes,sporangia are produced on sporophylls.
