Question

Which mode of nutrition is seen in Bryophytes?

Answer 1

The biochemical and physiological process by which an organism uses food to sustain its life is known as nutrition. Ingestion, absorption, assimilation, biosynthesis, catabolism, and excretion are all part of the process. Nutritional science is the branch of science that studies the physiological processes of nutrition.

Complete answer:
Bryophytes is a taxonomic division that includes the liverworts, hornworts, and mosses, which are non-vascular land plants (embryophytes). They are typically small and prefer moist environments, though they can survive in drier ones as well. About 20,000 plant species make up the bryophytes. Flowers and seeds are not produced by bryophytes, which produce enclosed reproductive structures (gametangia and sporangia). They reproduce by dispersing spores. Though bryophytes were once thought to be a paraphyletic group, almost all recent phylogenetic evidence now supports the monophyly of this group, as defined by Wilhelm Schimper in 1879.
Bryophytes have the following distinguishing characteristics:
1. A multicellular gametophyte stage dominates their life cycles.
2. The sporophytes of these plants are unbranched.
3. They lack true vascular tissue that contains lignin (although some have specialized tissues for the transport of water).
4. Bryophytes are members of the Plantae kingdom. They have chlorophyll and are capable of photosynthesis. As a result, they exhibit an autotrophic mode of nutrition.
What are the different types of Nutrition?
The process of ingesting food and converting it into energy and other essential nutrients for survival is known as nutrition. In general, there are two types of nutrition in living organisms:
autotrophic mode: In the autotrophic mode, organisms synthesize food on their own using simple inorganic matter such as water and carbon dioxide in the presence of light and chlorophyll.
Heterotrophic mode: Organism that does not prepare their food on their own. Such organisms are reliant on others for food. Heterotrophs are organisms that cannot produce food on their own and must rely on other organisms or sources.

Note:
Bryophytes have characteristics that make them beneficial to the environment. Bryophytes have been shown to help improve water retention and air space within soil depending on the plant texture. In pollution studies, bryophytes are used to detect soil pollution (such as heavy metals), air pollution, and UV-B radiation.
