Answer:
Equisetum (sphenophyta) plant
Explanation:
Equisetum plants are also termed "scouring rushes" because the epidermal cells have silica. This plant occurs in most tropics.
The Equisetum possess *branched stem* the form of whorls of leaves fused along most of the their own length to form ahead sheath joined at the node..Each *leaf contains a singular vascular bundle or *vein(single vein)* to the vascular tissue of the stem. The aerial and underground portion of the stems have epidermal cells with scattered stomata on them.
A cross section of the stem shows that inside the epidermal cells are thick-walled, which protect and support the plant. The cortex has a set of thin walled photosynthetic cells, which aid small leaves in photosynthesis.
