The life cycle of seedless vascular plants.

. The gametophyte is now less conspicuous but still independent of the sporophyte. Sporangia produce spores that develop into. Most plants exhibit alternation of generations Gametophyte - haploid Sporophyte.

In the life cycle of a fern the sporophyte generation is dominant. Water serves as a means to disperse spores away from the parent sperm swim through the water to fertilize the female egg. Figure below shows a typical fern life cycle.

Phylum Pterophyta Ferns As indicated in 1 of. The dominant phase of the life cycle of hornworts is the short blue-green gametophyte. Haplontic - refers to life cycle in which there is a dominant haploid stage algae.

The seedless vascular plants go through an alternation of generations just as the nonvascular plants and other vascular plants do. Some protists also have an alternation of generations life cycle but the structures that produce gametes in protists are usually single cells. The undersides of the leaves are dotted with clusters of sporangia.

Sperm are produced in structures called antheridia. The difference between seed plants and seedless plants is that seedless plants do not bear seeds for propagation whereas seed plants bear seeds for multiplication. The three groups lycophytes sphenophytes and pterophytes of seedless plants.

Include in the life cycle 2N N sporophyte gametophyte meiosis spores egg sperm antheridium archigonium fertilization sorus. Life Cycle of Seedless Vascular Plants. In seedless vascular plants the diploid sporophyte is the dominant phase of the life cycle.

The life cycle of seedless vascular plants alternates between a diploid sporophyte and a haploid gametophyte phase. The diploid sporophyte however is the more prevalent noticeable generation. Describe the adaptations in members of this group that allow them to be successful in terrestrial environments.

Figure1 A mature sporophyte fern has the familiar leafy fronds. They have a similar life cycle to that of seed-bearing plants. Phylum Pterophyta Ferns As indicated in 1 of the website use the space below to draw a simple life cycle of the fern.

Plants produce gametes in multicullar structures that have an outer protective layer. At grade 7 8. Identify the characteristics of non-vascular plants.

A group of plant species that utilize spores instead of flowers or seeds for reproduction is known as a bryophyte. Evolved from green algal ancestor nonvascular seedless vascular seed plants. The life cycle pattern in both Pteridophyta and Spermatophyta is basically same.

For a plants life cycle the diploid sporophyte is the most prominent while the gametophyte is a less noticeable but autonomous organism. Covers reproduction in nonvascular and vascular seedless plants. Seedless plants like these horsetails Equisetum sp thrive in damp shaded environments under the tree canopy where dryness is a rare occurrence.

Seedless vascular plants still depend on water during fertilization as the flagellated sperm must swim on a layer of moisture to reach the egg. Diplontic - refers to a life cycle in which diploid is a dominant stage humans. Plants in both divisions exhibit alternation of generations.

The non-vascular seedless plants which include mosses liverworts and hornworts are classified as bryophyt. The haploid plant that produces gametes is called a gametophyte. During the seedless vascular plants life cycle there occurs an alternation of plant evolution in which the diploid sporophyte alternates.
