Question

Select out the anatomical features regarded as advanced which can be used to raise a cladogram

• A. Stomata with subsidiary cells
• B. Presence of medullary vascular bundles
• C. Presence of external phloem in vascular bundles
• D. Vascular bundles arranged in single ring

Answer 1

The correct option is A Stomata with subsidiary cells

The cladogram is a tree or diagram that represents the phylogenetic relationship between the groups of plants and animals from their ancestors. There are several features that constitute a cladogram like roots, nodes, similarities etc. The advance anatomical feature used to make a cladogram is the stomata, it can be compared with the ancestors by its shape, the position of structures, as well as the subsidiary cell number and structure, differs in dicots and monocots. All this results in the phylogeny of plants.

So, the correct option is 'Stomata with subsidiary cells'.
