Archegonia are shaped like the flask you use in a laboratory and not the one from which you drink a beverage. The sperm are produced within tiny, typically stalked, club-shaped structures called antheridia and you can also see bryophyte sperm referred to as antherozoids.

The sperm will remain inside of the cell that produced it until it fully matures. So, let's go over what was covered in this lesson. These spores can survive in bad conditions and form vegetative cells when conditions are better. Why is it beneficial/essential for them to produce so many spores and why is the number of spores is detrimental to many people.? What shape are the bacteria classified as bacillus subtilis?

A sporophyte is the spore producing form of the plant. Prevent phagocytic white blood cells from taking them up and destroying them. sperm with flagella (as in bryophytes and pterophytes) swim from the antheridia to the archegonia through water droplets or dew. The archegonium also serves as the site of fertilization. Fusion of an egg and a sperm (syngamy) creates a zygote and restores the 2 n ploidy level. first two years of college and save thousands off your degree.
