The trabeculae found in Selaginella are the modification of
1 Epidermal cells
2 Cortical cells
3 Endodermal cells
4 Pericycle cells
Explanation:
The trabeculae found in Selaginella are the modification of endodermal cells. The innermost layer of the cortex is called endodermis. It comprises a single layer of barrel - shaped cells without intercellular spaces.

Antherozoids of Dryopteris are
1 multi ciliated and coiled
2 multi ciliated and sickle-shaped
3 biciliated and coiled
4 biciliated and sickle-shaped
Explanation:
Antherozoids of Dryopteris are multiciliated and coiled, which have a prominent vesicle and a nucleus. Dryopteris consists of a mature antheridium which is made up of a layer of jacket cells, with two ring shaped each composed of either one or two cap cells.
