Question

Consider the cladogram showing the evolutionary relationships among certain groups of plants. Clade B separates from the club and spikemosses and quillworts because plants on this branch all have
A) seeds.
B) spores.
C) vascular tissue.
D) true leaves, stems, and roots.

Answer 1

Answer: Option B spores

Explanation:

These plant groups contain the Spores which helps in reproduction. The spores are moved through wind and water. There are 400 species of club mosses, 150 species of quillworts and 700 species of spike mosses. Club mosses and spike mosses are similar to look and they grow on the forest floors.

They do not have any seeds. The stems and roots grow below the ground level hence it is not visible on the surface. The leaves are very small and only leaves are the actual plant.

Answer 2

Clade B separates from the club and spikemosses and quillworts because plants on this branch all have true leaves, stems, and roots..

Explanation:

All three groups of lycophytes have really different types of development, but they really do share a number of characteristics. Lycophytes have distinctive leaves that distinguish them from all other classes of plants. Their plants, classified as microphylls, have just one vein running along the length of the vine.

In reality, the stems of quillworts develop below the ground and the leaves develop only from the tip of the stem that sits at the ground level.

Club mosses and spike mosses produce roots from above ground, known as adventitious roots, and then develop into the surface. The roots of the Quillwort emerge from the base of their underground core.
