Diagram Of A Fern
The life cycle of a fern is very different from the life cycle of many other plants.
Diagram of a fern. Ferns are one of the earliest forms of plant life on the planet living over 300 million years ago according to the american fern society. Gametophyte plants are haploid sporophyte plants diploid. The rhizome the underground stem the leafy frond and the sporangia the reproductive structure.
What are the 2 functions of a fern frond. The following describes fern structure and forms that people typically encounter. It only makes sense then that having racked up so much time on earth ferns have evolved into over 12 000 different species today.
Sporophyte which releases spores and gametophyte which releases gametes. A fern polypodiopsida or polypodiophyta ˌ p ɒ l i ˌ p ɒ d i ˈ ɒ f ɪ t ə oʊ f aɪ t ə is a member of a group of vascular plants plants with xylem and phloem that reproduce via spores and have neither seeds nor flowers they differ from mosses by being vascular i e having specialized tissues that conduct water and nutrients and in having life cycles in which the sporophyte. There are two distinct stages in the life cycle of ferns.
The mature fern plant is the sporophyte structure that produces spores which are released from sporangia. The first stage is that of the gametophyte. Fronds are usually composed of a leafy blade and petiole leaf stalk.
To follow the life cycle of the fern begin at number one below. Fern class of several thousand species of nonflowering vascular plants that reproduce by spores. The spore will undergo mitosis in order to create many identical haploid cells.
Ferns have true roots stems and complex leaves and constitute an ancient division of plants. Leaf shape size texture and degree of complexity vary considerably. While many plants grow a mature adult form straight out of the seed ferns have an intermediate stage called a gametophyte which then grows into a mature fern.
