Subject and Association Description

The fern is a seedless vascular plant that reproduces via spores. Instead of flowers or seeds, ferns have a complicated life cycle in which the appearance of the plant alternates between generations. Depicted on the left side of the chart is a fern in the sporophyte phase. The sporophyte produces spores, the small round brown figures shown magnified on the back of the leaf. The spore divides by mitosis, shown in consecutive steps, into a heart shaped gametophyte. A gametophyte can be male or female, hence the two different renditions. This adult form, shown in the middle row at microscopic level, has two sets of reproductive organs that produce gametes, or sperm and eggs. The sexual reproduction between two gametes grows outward from the gametophyte into a sporophyte fern.
