How can we make sporopollenin?
Sporopollenin is complex compound present in the exine of pollen grains. As such, it can be extracted from pollen grains.
Does pollen contain the sporophyte?
No, pollen grain does not contain the egg of the plant. It contains the male gamete of the plant.Egg of the plant is present in the ovaries.
How germinated pollen grain looks like under microscope?
pollen grains under the microscope with information on treatment, so as to keep them hydrated with various solutions. Building up a collection of pollen for permanent mounts is possible; tips are also given here on how to be successful.
How do you make unbreakable bubbles?
Make them out of iron
What can you make out of quartz?
You can make countertops and jewelry.

The structural integrity of plant spores is to?
the structural integrity of plant spores is sporopollenin
What are moss spores coated with?
sporopollenin
What is the pollen case?
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.
What is the significance of sporopollenin in bryophytes?
It forms the spore wall, resistant to degradation by enzymes and chemicals, thus protecting the spores.
Is pollen a part of geology?
Pollen grains can be preserved for thousands and thousands years due to the covering of sporopollenin on their exine, hence study of these pollens in fossil form is possible. Therefore, pollen is a part of geological studies.
Does pollen contain the sporophyte?
No, pollen grain does not contain the egg of the plant. It contains the male gamete of the plant.Egg of the plant is present in the ovaries.
What is pollen made up of?
Pollen is a fine to coarse powder containing the microgametophytes of seed plants, which produce the male gametes
What is pollen analysis?
Pollen grains are the microscopic male reproductive particles released from flowering plants. As these grains are vital for the survival of flowering species, evolution has ensured that individual species produce different types of pollen grains. Pollen grains are also made of a resistant organic material (sporopollenin) that means they are often remarkably well-preserved in sediments many thousands of years old.

What do new fern plants form?
New fern plants grow out of spores into gametophytes. There are male and female gametophytes that produce gametes respectively. Because ferns are pteridophyta, they lack sporopollenin to provide transportation of sperm in the absence of water. In the presence of water, the antheridia of the gametophytes release sperm, which travel through the water and swim into the archegonia of other gametophytes, where the egg and sperm fuse together to form a zygote. This zygote grows into a sporophyte, which is what you typically see and recognize as a fern.
