Question

Stelar system present in family Cucurbitaceae is

• A. Siphonostele
• B. Amphiphloic solenostele
• C. Dictyostele
• D. None of the above

Answer 1

The correct option is D None of the above

In all vascular plants, the stele is the central part of the root or stem with or without the pith. The pericycle is the outermost boundary of the stele. Steles are differentiated into protostele and siphonostele. The siphonostele are further divided 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 gaps is a solenostele. 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. However, of all these type of stelar systems, none of them is observed into the family of Cucurbitaceae.

Thus, the correct answer is option D.
