Answer:
Correct Answer: B
Solution:
In young stems of Funaria, the cortical cells contain chloroplasts, hence, they are photosynthetic.
The central cylinder forms the core of the stem.
It consists 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.
