Thallophytes (Thallophyta, Thallophyto, or Thallobionta) are a polyphyletic group of nonmotile creatures known as "thalloid plants," "very basic plants," or "lower plants." They are part of the Plantae kingdom, which also includes lichens and algae, as well as bryophytes, bacteria, and slime molds. However, unlike cormophytes, thallophytes have undifferentiated bodies with stems and roots.
Different types or groupings of Thallophytes contribute significantly to the overall sphere and dynamism of the marine environment. Various thallophyte groups make important contributions to marine environments. In 1836, Stephan Endlicher, an Austrian botanist of the 19th century, divided the vegetative world into thallophytes (algae, lichens, fungi) and cormophytes (containing bryophytes and therefore being equal to Embryophyta in this case). Cormogens were a significantly smaller group than Endlicher's cormophytes, consisting of just ferns (including Equisetopsida) and lycopodiophytes.
Thallophyta is a division of the plant kingdom that includes primordial forms of plant life with a basic plant body. The first 10 phyla are known as thallophytes. They are basic plants with no stems, roots, or leaves. They are not embryophytes. These plants thrive mostly in water.
Thallophyta examples are as follows-
The thallophyta are classified into two groups-
Thallophytes are a polyphyletic collection of non-mobile organisms that exhibit similarities in traits but do not share a common ancestor. They were previously classified as a sub-kingdom of the kingdom of Plantae.

The following are some of the characteristics of thallophyta-
If we look at the overall structure or division of the plant kingdom, Thallophyta is at the bottom. It does not have a well-structured body design. It means that there is no structure in the plant's body, such as roots, stems, or leaves. These plants are always aquatic and are generally referred to as algae. However, in addition to the above-mentioned plant kingdom segmentation, a sub-division of this specific plant is accessible. Thallophyta is divided into two major divisions-
These are the chlorophyll-containing thalloids. They are generally autotrophic aquatic plants. The algae protect the sloth from predators by providing it with camouflage and extra nourishment. Spirogyra is one of the most prevalent and significant instances. Some of the fundamental properties of algae are as follows-
They are achlorophyllous (don't make chlorophyll). heterotrophic thallophytes. To offset this disadvantage, the fungus may form a symbiotic connection with an alga or a cyanobacterium. Because algae contain chlorophyll, they can create food, and the fungus offers a protective habitat that protects the algae from UV radiation. Lichen is an example of two species working together as one. Fungi have the following characteristics-

Ans. Thallophyte has the following properties- 1. Thallophyte sex organs are single-celled organisms. 2. There is the option of generating an embryo after fertilization is completed. 3. It is distinct from other plants in that it lacks phloem and xylem. 4. This plant lacks vascular tissue. 5. There is no cellulose cell wall in these plant cells.
Ans. Thallophyte is a plant kingdom division that includes primordial forms of plant life with a basic plant body. Algae, fungi, and lichens range in size from unicellular to multicellular. The first 10 phyla are known as thallophytes. They are basic plants with no stems, roots, or leaves.
Ans. It is a multicellular haploid creature that originates from a haploid spore with one pair of chromosomes. The sexual phase of the plant and algae life is known as the gametophyte.
Ans. Algae are grouped into the following groups- 1. Algae that is blue-green. 2. Algae that is red. 3. Algae that is green.
