Content: It is anchored to the ground by rhizoids, which are less complex than roots found in vascular plants. This haploid stage is capable of photosynthesis and supports the life functions of the plant. The Diploid Stage
The diploid stage begins following fertilization. Sperm are released from the antheridia and swim - using flagella - to a female archegonia. Once the haploid egg and sperm fuse, there is now a zygote. This new diploid cell will divide through mitosis to eventually become the mature sporophyte. Keep in mind that the sporophyte is dependent upon the gametophyte for nutrition and support. The sporophyte actually grows within the archegonia. It will develop a foot that attaches to the gametophyte. A stalk will then grow out of the archegonia.
