Question

If a stele has one leaf gap, it is called as

• A. Solenostele
• B. Dictyostele
• C. Siphonostele
• D. Eustele

Answer 1

The correct option is A Solenostele

Stele is a column containing vascular tissues which is surrounded by pericycle and separated from ground tissue by endodermis. If a stele has one leaf gap, it is called as solenostele. The siphonostele are differentiated into solenostele, dictyostele and eustele. A type of siphonostele, in which the vascular tissue in the stem forms a central cylinder around a pith with widely spaced leaf gap is a solenostele. The primary vascular tissue consists of vascular bundles, usually in one or two rings around the pith is called as eustele. A stele in which the vascular cylinder is broken up into a longitudinal series or network of vascular strands around a central pith is called as dictyostele.
Thus, the correct answer is option A.
