Thallophyta plants with name seprate
Answers
Answer:
Explanation:
a polyphyletic group of non-mobile organisms traditionally described as "thalloid plants", "relatively simple plants" or "lower plants". These plants mainly grow in water. They were a defunct division ofkingdom Plantae that included fungus, lichensand algae and occasionally bryophytes,bacteria and the Myxomycota. Thallophytes have a hidden reproductive system and hence they are also called Cryptogamae (together with ferns), as opposed to Phanerogamae. The thallophytes are defined as having undifferentiated bodies (thalli), as opposed tocormophytes (Cormophyta) with roots and stems.
Examples of thallophyta are;
Spyrogyra
Ulothrix
Cladophora
2)bryophyta :-Bryophytes are an informal group consisting of three divisions of non-vascular land plants (embryophytes): the liverworts, hornworts andmosses.[1] They are characteristically limited in size and prefer moist habitats although they can survive in drier environments.[2] The bryophytes consist of about 20,000 plant species.[3][4] Bryophytes produce enclosed reproductive structures (gametangia and sporangia), but they do not produce flowers orseeds. They reproduce via spores. Bryophytes are usually considered to be a paraphyleticgroup and not a monophyletic group, although some studies have produced contrary results. Regardless of their status, the name is convenient and remains in use as an informal collective term. The term "bryophyte" comes from Greek βρύον, bryon "tree-moss, oyster-green" and φυτόν, phyton "plant".
There are many examples of Bryophyte but first of all mainly Bryophyte are divided into 3 main groups which discribe as follow
LiverwortHornwortAnd the most commonly known areMosses
3)pteridophyta:-
Polypodiophyta: Athyrium filix-femina

Lycopodiophyta: Lycopodiella inundata
A pteridophyte is a vascular plant (with xylemand phloem) that disperses spores (and lacks seeds). Because pteridophytes produce neither flowers nor seeds, they are also referred to as "cryptogams". The pteridophytes include the ferns, horsetails, and the lycophytes (clubmosses,spikemosses, and quillworts). These are not amonophyletic group because ferns and horsetails are more closely related to seed plants than to the lycophytes. Therefore, "Pteridophyta" is no longer a widely accepted taxon, although the term pteridophyte remains in common parlance, as do pteridology andpteridologist as a science and its practitioner, to indicate lycophytes and ferns as an informal grouping, such as the International Association of Pteridologists and the Pteridophyte Phylogeny Group.

Answer:
Explanation:
Thallophytes are a polyphyletic group of non-mobile organisms that are grouped together on the basis of similarity of characteristics, but do not share a common ancestor. They were formerly categorized as a sub-kingdom of kingdom Plantae. These include lichens, algae, fungus, bacteria and slime moulds and bryophytes.
Characteristics of Thallophyta
Thallophyte
They are usually found in moist or wet places.
This is due to the absence of “true roots” and vascular tissue that is needed to transport water and minerals. Hence they are found in moist or wet places.
They are autotrophic in nature.
Most members in this group manufacture their own food. But a few members like fungi are dependent on other sources of food.,
Reserve food is generally starch.
After photosynthesis, glucose is produced and consumed almost immediately, the remaining glucose is converted into complex compounds called starch.
They have a cell wall composed of cellulose around their cells.
Absence of vascular tissue.
Unlike other plants, xylem and phloem are absent. etc
Sex organs are simple, single-celled, there is no embryo formation after fertilization.
Division of Thallophyta
The division Thallophyta is classified into two subdivisions: Algae and Fungi.
Division of Thallophyta
Algae
They are chlorophyll-bearing thalloids. They are autotrophic and largely aquatic plants. On a side note, it has been observed that green algae forms a symbiotic relationship with sloths that are native to the lush tropical rainforests of South America and Central America. Sloth fur is very coarse and readily absorbs water. As a result, sloth fur forms a moist and damp environment for the algae to flourish. The algae in return, provides the sloth with extra nutrition and camouflage from predators. Example: Spirogyra.
Fungi
They are achlorophyllous (meaning: they do not produce chlorophyll) heterotrophic thallophytes. Sometimes, to overcome this handicap, fungi may develop a symbiotic relationship with an algae or a cyanobacterium. The algae can produce food as it has chlorophyll and the fungi in return provide a safe environment that shields the algae from UV rays. Lichen is an example where two organisms act as a single unit.
