Answer:
1.Ferns generally reproduce by producing spores. Similar to flowering plants, ferns have roots, stems and leaves. However, unlike flowering plants, ferns do not have flowers or seeds; instead, they usually reproduce sexually by tiny spores or sometimes can reproduce vegetatively, as exemplified by the walking fern.
2.The structure of a fern. Ferns have 3 major parts – the rhizome, the fronds and the reproductive structures called sporangia. The characteristics of each of these 3 parts of the fern plant are used for classification and identification. The rhizome is the stem of the fern plant.
3.The ferns are also well adapted to wide range of environmental conditions and can be found in a number of different habitats. They are most common in rainforest where they commonly grow on other plants but they can also be found in grasslands, deserts and lakes.
4.Fertilisation occurs when the fern's egg and sperm combine to form a zygote. Ferns require water to enable the movement of the sperm to reach the egg. A zygote is a combination of genetic material from both the egg and sperm and contains a complete set of DNA to form a new fern plant.
5. Nestled under fern leaves are tiny capsules chock-full of spores, tiny life vessels which, like seeds, are used for dispersal. Fern plants launch their spores with tiny catapults. Once in the air, wind and air currents can take the spores around the world.
6.Most ferns reproduce sexually, and that involves meiosis and fertilisation. When you are thinking of the typical big fern plant, what it does is, by meiosis, produces spores, and spores have half the number of chromosomes of the big parent plant. The spores are released into the wind.
