Jul 01, 2017 · Question 16 1 / 1 pts Which group has the only non-vascular land plants? Bryophytes Pterophytes (ferns) Gymnosperms Angiosperms Question 17 1 / 1 pts True or False: Mushrooms have been around longer than Bryophytes.
Write the characteristics and adaptations that belong only to nonvascular or vascular plants in the appropriate circle. For those characteristics and adaptations that apply to both, write them in the portion in which the circles overlap. If a characteristic or adaptation is not the same for all members of a particular group (i.e. non-vascular or vascular), you should qualify your answer.
Nov 13, 2019 · Seedless Vascular Plants There are two phyla of non-flowering vascular plants. These include the Monilophytes, the ferns; and the Lycophyta, or club mosses. In these plants, a vascular system connects the leaves, stems and roots. The sporophyte is dominant in all plants in this group. There are two types of leaves identified in this group.

Bryophytes, an informal group that taxonomists now treat as three separate land-plant divisions, namely: Bryophyta (mosses), Marchantiophyta (liverworts), and Anthocerotophyta (hornworts).
By examining the four major groups of living plants, you will be able to review the adaptations that enabled the first non-vascular and vascular plants to survive on land. These are the mosses (non-vascular plants), the ferns (seedless, vascular plants), gymnosperms and angiosperms.

Scientists have identified more than 260,000 kinds of plants. They classify plants according to whether they have body parts such as seeds, tubes, roots, stems, and leaves. The three main groups of plants are seed plants, ferns, and mosses.
Plant defenses are adaptations that reduce the damage and mortality caused by herbivores and pathogens. Here we describe the diverse array of features that have a defensive role in plants. Most prominent are chemical defenses that plants use to deter or poison their natural enemies.
The important role of secondary plant substances in plant defense was described in the late 1950s by Vincent Dethier and G.S. Fraenkel.
Physical defences Many plants are covered with a thick bark. This is an external layer of dead cells which forms a physical barrier against infection. In this way, it is very much like skin. Each plant cell has a cellulose cell wall which acts as another barrier against infection.
