Explanation
Selaginella is a type of fern that belongs to the division Lycopodiophyta. It is a vascular plant that has both xylem and phloem tissues. Selaginella leaves have stomata, which are tiny openings that allow for gas exchange, and are responsible for transpiration and photosynthesis. However, Selaginella leaves do not have palisade parenchyma, which is a specialized type of leaf tissue found in the leaves of angiosperms. Palisade parenchyma is responsible for photosynthesis in angiosperms.
