Detailed explanation-1: -The green plants are further divided into the two groups: the vascular plants and the non-vascular plants. The vascular plants are further divided into the two groups: the seed plants and the non-seed plants. The seed plants are further divided into the two groups: the gymnosperms and the angiosperms.
Detailed explanation-2: -The two types of vascular tissue are phloem, or the food-conducting tissue, and xylem, or the water-conducting tissue.
Detailed explanation-3: -Nonvascular Plants. Nonvascular plants (often referred to collectively as the bryophytes) include three groups: the mosses (Bryophyta), approximately 15, 000 species; liverworts (Hepaticophyta), approximately 7500 species; and hornworts (Anthocerophyta), approximately 250 species (Table 1).
