Correct Statements about Clubmosses:

- Attach to Substrate with Rhizoids: - Clubmosses attach to the substrate using rhizoids, which are root-like structures that help them anchor and absorb water and nutrients [[5]].

- Life Cycle Includes a Prothallus (Gametophyte) Stage: - In the life cycle of clubmosses, there is a stage called the prothallus or gametophyte, which is a small, independent, heart-shaped structure that produces gametes [[6]].

- Large, Divided Leaves: - Clubmosses have large, divided leaves that are characteristic of their appearance [[7]].

- Spores Develop in Sporangia Arranged in Strobili: - The spores of clubmosses develop in sporangia, which are arranged in cone-like structures called strobili [[8]].
