Question

Strobili or cones are found in :

• A. Salvinia
• B. Pteris
• C. Marchantia
• D. Equisetum

Answer 1

The Correct Option is D

To answer the question of where strobili or cones are found, it's important to understand what strobili are and which plant groups typically possess them.

Explanation of Options:

• Salvinia: Salvinia is a genus of floating ferns. Ferns do not produce cones; instead, they reproduce through spores found under their fronds.
• Pteris: This is another genus of ferns. Like Salvinia, Pteris relies on spores for reproduction and does not produce strobili or cones.
• Marchantia: Marchantia is a genus of liverworts, which are non-vascular plants. They reproduce using gemmae and spores but do not produce cones.
• Equisetum: Commonly known as horsetails, Equisetum is a genus of non-flowering plants that reproduce by spores and form strobili, or cone-like structures, at the tips of their stems.

Conclusion:

The correct answer is Equisetum because it is the only option that features plants known for having strobili or cone-like structures that aid in reproduction.
