Plants that do not have well - differentiated body design fall in this group. The plants in this group are commonly called algae. This group is ______.

The correct answer is Thallophytes

Key Points

• Thallophytes:-
  • These are a diverse group of organisms that includes both unicellular and multicellular plants.
  • They are found in a wide range of habitats, from freshwater and marine environments to terrestrial environments.
  • Thallophytes do not have true roots, stems, or leaves. Instead, their bodies are typically flattened and leaf-like, and they absorb water and nutrients directly from their environment.
  • The group of plants that do not have a well-differentiated body design and are commonly called algae is thallophyta.
  • Examples of thallophytes include:
    • Green algae: Spirogyra, Ulothrix, Cladophora
    • Brown algae: Fucus, Laminaria, Sargassum
    • Red algae: Porphyra, Gelidium, Gracilaria

Additional Information

•  Gymnosperms:-
  • These are a group of plants that produce seeds but do not have flowers.
  • They include conifers, cycads, ginkgoes, and others.
  • Gymnosperms have a higher number of species compared to bryophytes and algae.
  • Gymnosperms are typically slow in terms of reproduction; up to a year may pass between pollination and fertilisation and seed maturation may require 3 years.
• Bryophytes:-
  • These are a group of non-vascular plants that includes mosses, liverworts, and hornworts.
  • They are called non-vascular plants because they do not have specialized tissues for transporting water and nutrients, such as xylem and phloem.
  • Bryophytes are typically small plants that grow in moist, shady environments. They are found all over the world, from the Arctic to the tropics.
• Pteridophytes:-
  • These are vascular plants that reproduce by spores.
  • They are also known as ferns and lycophytes.
  • Pteridophytes were the first vascular plants to colonize the land, and they played a major role in the evolution of plant life.
