TOPIC: SEEDLESS VASCULAR PLANTS IDENTIFICATION 1. Type of leaves that are generally larger in size and has complex venations. 2. This group is characterized by the presence of an nonvascularized root in the form rhizoids, presence of a dichotomous branching stem which resembles a whisk. 3. More commonly known as vascular plants, this refers to a large group of land plants with lignified tissues for conducting water and minerals.
