It forms the spore wall, resistant to degradation by enzymes and chemicals, thus protecting the spores.
* bryophytes are good indicators of environmental pollution, particularly eutrophication where u have more calcium and nutrient content in water. * they r good indicators of soil PH * Bryophytes help prevent soil erosion * they are excellent seedbed for most coniferous trees * they are good source of fuel

Sporopollenin is complex compound present in the exine of pollen grains. As such, it can be extracted from pollen grains.
We, as humans can not but we can in the laboratory.
compare the bryophytes and trcacheophytes
Ferns are vascular, bryophytes are not.
No. Bryophytes include liverworts, hornworts, and moss.
Bryophytes are small, low growing plants that are found in moist environments. Bryophytes do not have lignified tissue. Lignified tissue is hard like a tree bark.
The process of photosynthesis is similar in tracheophytes, algae and bryophytes.
What is usually meant by pollen case is the outer protective coat of the pollen grain. It is a highly modified cell wall, with two layers. The interior layer is largely pectocellulose (a combination of pectin and cellulose) with a bit of callose, and the exterior is made of sporopollenin. Sporopollenin is so tough that its exact chemical structure has not been figured out. Atop the sporopollenin layer is a deposit of sticky goo made of pollenkitt and/or tryphine.
No, lichens are not bryophytes. Lichens are symbiotic organisms composed of a fungus and an alga or cyanobacterium, while bryophytes are non-vascular plants such as mosses, liverworts, and hornworts.
The structural integrity of plant spores is crucial for protecting the genetic material inside from environmental stresses such as desiccation, UV radiation, and physical damage during dispersal. The tough outer layer of the spore, called the sporopollenin layer, plays a key role in providing mechanical strength and chemical resistance, ensuring the spore's viability and successful dispersal.
