Explanation

In young stems of Funaria, the cortical cells contain chloroplasts, hence, they are photosynthetic. The central cylinder forms the core of the stem. It consits of vertically elongated , thin-walled, narrow, compactly arranged cells without protoplasm. These thin walled, elongate, dead cells with nonlignified walls are commonly called the hydroids.
