Annually cause 5000 million infections and 3 million deaths. Seen in both tropical and cool temperate climates. Possess small, delicate sporangia that develop from a single cell. Sporophytes become dominant life stage stem bearing true leaves and roots often stems are underground rhizomes. Many fern stems have a dense covering of scales or hairs, which are modi cations of. Fern gametophytes are small, free-living, heart-shaped thalloid structures that bear epidermal cells rhizoids and sex organs. Animals established their body plans prior to colonisation of the land. Land plants developed their body plans after they colonised terrestrial environments. Di erences between terrestrial environment and marine environment plants surrounded by water in marine environments drought vs lots of water? osmosis in marine plants stomata in land plants.
