Which of the following sets of plants is correctly paired with the...

$\textit{Marchantia}$ and $\textit{Funaria}$ belong to bryophytes. In bryophytes, the dominant phase in the life cycle is the gametophyte, and vascular tissues are absent.

$\textit{Selaginella}$ and $\textit{Equisetum}$ belong to pteridophytes. In pteridophytes, the main plant body is a sporophyte which is differentiated into true root, stem, and leaves. These organs possess well-differentiated vascular tissues (xylem and phloem).

$\textit{Cycas}$ and $\textit{Cedrus}$ belong to gymnosperms. In gymnosperms, the dominant phase is the sporophyte, and vascular tissues are present.

$\textit{Spirogyra}$ and $\textit{Volvox}$ belong to algae. In algae, the dominant phase is the gametophyte, and vascular tissues are absent.

Answer: $\textit{Selaginella}$ and $\textit{Equisetum}$ : Dominant sporophyte, Vascular tissues present
