Answer 2

Option C) Sporangiophore is correct.

The sporangiophores, which group together to form a compact structure known as a strobilus cone or sporangiferous spike, are where the sporangia are born.

Equisetum:

• An aerial portion and an underground rhizome portion make up the body of the Equisetum plant.
• Perennial, horizontal, branching, and creeping are the characteristics of the rhizome.
• The aerial portion is typically annual and herbaceous.
• The majority of species are tiny, with heights and diameters ranging from 15 to 60 cm and 2.0 cm, respectively.
• Equisetums typically grow in moist or damp environments, and they are especially prevalent at the sides of streams and irrigation canals.
• Equisetum's sporophyte plant body is divided into a stem, roots, and leaves.

The strobilus is made up of an axis with sporangiophores arranged in whorls. A hexagonal peltate disc is located at the distal end of each sporangiophore, which is a stalked structure. Five to ten elongate, cylindrical hanging sporangia are carried in a ring towards the periphery on the underside of the sporangiophore disc.
