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

the structural integrity of plant spores is sporopollenin
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
No. Bryophytes include liverworts, hornworts, and moss.
Ferns are vascular, bryophytes are not.
Angiosperms have vascular tissue, bryophytes dont
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.
