• A. Actinostele
• B. Haplostele
• C. Meristele
• D. Plectostele

Answer 1

Answer:

C. Meristele

The vascular part of a dictyostele between two leaf gaps is called a meristele.

• A dictyostele is a type of stele (the central part of the plant root or stem containing vascular tissue) where the vascular cylinder is dissected into a network of bundles by overlapping leaf gaps.

• A leaf gap is a parenchymatous region in the vascular cylinder of a stem that is formed just above the point where a leaf trace (the vascular tissue supplying a leaf) departs.

• The individual vascular bundles that make up the network of a dictyostele are called meristeles. Each meristele is a separate, concentric vascular bundle with a central xylem surrounded by phloem.
