Introduction :
The diversity of plants and its classification depends on adaptation. The plants are classified into twelve divisions. These twelve divisions of plants are divided into two groups; the non-vascular plants and the vascular plants. The non-vascular plants have lack of specialized transport tissue while the vascular plants have specialized transport tissue.
Answer to Problem 20A
Correct answer :
The correct answer is option (C) vascular.
Explanation of Solution
Explanation/justification for the correct answer :
Option (C) vascular. The seedless vascular plants are one of the three group of plants with vascular tissue. They have many forms of diversity and size. They include mosses, hornworts, and liverworts. So, the correct answer is option (C).
Explanation for incorrect answer :
Option (A) Nonvascular. The nonvascular diversity of plants is mostly evolved from green algae. They are small in size and enable any materials to move within it. So, this is an incorrect option.
Option (B) flowering. The flowering plants are also considered as anthophytes. They are found in both terrestrial and aquatic conditions. They are seed bearing and are termed as
Option (D) seed producing. They are the seed bearing plants or they are considered as cotyledons. They involve cycadophyta, gnetopyta, etc. So, this is an incorrect answer.
