1.Ferns also have Fiddleheads which unroll into the leaves of the fern.
2.Ferns are homosporous-producing only one spore.
3. Now the sex life:
a.The (N) spores are produced by the sori- the red or brown dots on the underside of the leaves.
b.Sorus( The singular form of sori) is a group of sporangia(spore forming organs). The sporangia are sometimes hidden in the indusium- A scalelike cover.
c.When the sporangia ruptures the spores are allowed to become windborne.
d.Later when a fern spore germinates a tiny heart shape forms. This is called the prothallus.
e. Then the sperm forms in the antheridia and the egg forms in the archegonia.
