Types of Plants: The Four Major Classifications of Plants Bryophyte Examples. Also the next classification of plants is also known as the tracheophytes, Pteridophyte Examples. Gymnosperms, as compared with other plant phyla, include the tallest, Gymnosperm Examples. Angiosperms, also four major classifications of plants Nov 27, 2007 There are four major types of plant hormones (or phytohormones) which are involved in the control and coordination in plants. These are: 1. Auxins, 2. Gibberellins, 3. Cytokinins, and 4. Abscisic acid (ABA). Auxins, gibberellins and cytokinins are the plant hormones which promote growth of plants.

Stem jointed nodes and internodes, leaves arranged in whorls around then these plants became extinct at the end of the Palaeozoic era. Four of these types of plants are found in the rocks of Lower Gond period. Spermatophyta: These are most modern plants with distinct root, trite branch, leaf, flower, fruit and seed. They propagate through seeds. four major classifications of plants

Classification: Plants, Other Organisms. Table presents the old groupings of plants in considerable detail because some of the names persist as common names for modern plant groups, for example, thallophytes, gymnosperms, and monocots. By and large, the major groups (such as ferns, mosses, and flowering plants) are still recognized as units in These differences in characteristics are used to group plants into species, which provides a way of classifying and therefore organizing plants. While there are many ways to structure plant classification, one way is to group them into vascular and nonvascular plants, seed bearing and spore bearing, and angiosperms and gymnosperms. How can the answer be improved? four major classifications of plants Students will be able to list the characteristics of the four major types of plants. Students will be able to define the following key terms: vascular, nonvascular, roots, stems and leaves, sexual reproduction and asexual reproduction. Students will classify plants in the four main groups as There are 280, 000 plants on Earth. Land plants solved this problem by developing roots as well as stems and leaves, and a system of vessels (xylem and phloem) to connect them. All four of the land plant groups have these features (except mosses do not have vessels). Their differences are seen in whether or not they have seeds or flowers, and in aspects of these features.
