Write 3 features of each division
Answers
Answer:
Division Thallophyta
These are the lowermost plants of the plant kingdom, without a well-differentiated body design. This means that the plant body is not differentiated as roots, stem, and leaves. They are commonly called algae, are permanently aquatic. Examples include Spirogyra, Chara, and Ulothrix.
Division Bryophyta
These are small terrestrial plants. They show differentiation in the body design, with stem, leaf-like structures, and root-like structures. But, they do not have any specialized tissue to conduct water and other substances. They live in damp and sandy habitats and are often referred to as the amphibians of the plant kingdom. Examples are Riccia, Funaria, and Marchantia
Division Pteridophyta
These are supposed to be the oldest vascular plants. The plant body is differentiated into roots, stem, and leaves, apart from having a specialized tissue for conduction. This tissue helps in the conduction of water and other substances from part of the plant to the other.
These plants have naked embryos called spores. The reproductive organs in these plants are inconspicuous. Examples: Marselia, Ferns
Division Phanerogamae
Phanerogams are seed-bearing plants. The plant body is well differentiated with stem, leaves, and roots. There are well differentiated reproductive tissues that produce seeds. These plants also have a well-developed vascular system.
Depending on whether the seeds produced are naked or whether they are enclosed, phanerogams are further classified into two subdivisions. They are Gymnosperms and Angiosperms
