Seedless plants have historically played a role in human life which uses as tools, fuel, and medicine.

Reason for the Incorrect options

• Club mosses, which are the earliest form of seedless vascular plants, are lycophytes that contain a stem and microphylls. They are ecologically minor components of all the ecosystems in which they occur. Their economic importance is also slight.
• Horsetails are often found in marshes and are characterized by jointed hollow stems with whorled leaves. Economic importance includes local medicinal uses, dye and fiber plants, weeds (some toxic to livestock).
• Most ferns have branching roots and form large compound leaves, or fronds, that perform photosynthesis and carry the reproductive organs of the plant. Ferns prevent soil erosion, promote topsoil formation, restore nitrogen to aquatic habitats by harboring cyanobacteria, make good house plants, and have been used as food and for medicinal remedies.
