what is thallophyta in plants kingdom
Answers
Answer:
Thallophytes (Thallophyta or Thallobionta) are a polyphyletic group of non-motile organisms traditionally described as "thalloid plants", "relatively simple plants" or "[lower plants]". They form an abandoned division of kingdom Plantae that include fungi, lichens and algae and occasionally bryophytes, bacteria and slime moulds. Thallophytes have a hidden reproductive system and hence they are also incorporated into the similarly abandoned Cryptogamae (together with ferns), as opposed to Phanerogamae. Thallophytes are defined by having undifferentiated bodies (thalli), as opposed to cormophytes (Cormophyta) with roots and stems. Various groups of thallophytes are major contributors to marine ecosystems

Answer:
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
Explanation:
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.
