Which group of plants is Homosporous?

Which group of plants is Homosporous?

ferns ferns. Most ferns are homosporous, each plant having spores of one shape and size, usually 30 to 50 micrometres in length or diameter, although some reach more than 100 micrometres. A few fern families, however, have dimorphic spores, small ones (microspores) and large ones (megaspores).

Do ferns have a Homosporous life cycle?

Simplified overview of the homosporous fern life cycle. ... Ferns, like all land plants, have a life cycle that alternates between multicellular diploid (spore-producing sporophyte) and multicellular haploid (gamete-producing gametophyte) phases, punctuated by meiosis and fertilization.

How do you tell if a plant is Homosporous or heterosporous?

What groups are land plants?

The kingdom Plantae contains four major groups of land plants: bryophytes, pteridophytes, gymnosperms, and angiosperms. Plant life is diverse, adaptive, and environmentally successful. This means they exist in many of Earth's ecosystems.

Is a Hornworts Homosporous?

Homosporous Land Plants. Background. As little as thirty years ago our understanding of the evolution of land plants was very different from what it is now. ... Bryophytes, that is mosses, liverworts and hornworts, represented the earliest land plants.

What is the lifespan of a fern?

Lifespan of fern depends on the species. Some types of ferns can live up to 100 years.

Where do ferns grow best?

Woodland ferns do best in high or dappled shade. The open shade of mature trees or the north side of the house or a wall, open to the sky, provide nearly ideal light conditions. Most woodland ferns will adapt to relatively low light levels, but no ferns thrive in deep shade.

Is ferns Homosporous or heterosporous?

Ferns are mostly homosporous, though some are heterosporous. The heterosporous state is a more advanced condition, that seems to have evolved independently in several groups of plants. The haploid spores are formed by meiosis inside the sporangium.

Does moss show Heterospory?

> Option A:Funaria, also known as Moss belongs to phylum Bryophyta. Bryophytes are homosporous and also Funaria is found near water. ... Since Bryophytes are homosporous, they do not show heterospory.

Are there any ferns that are heterosporous or homosporous?

Polypodiophytes (ferns) also have homosporous (most ferns, including Equisetum - horsetails) and heterosporous (Salvinia - water ferns, Marsillea - clover ferns, and Azolla - mosquito ferns) groups.

How big are the spores of a fern?

Most ferns are homosporous, each plant having spores of one shape and size, usually 30 to 50 micrometres in length or diameter, although some reach more than 100 micrometres. A few fern families, however, have dimorphic spores, small ones (microspores) and large ones (megaspores).

Is the polypodiophyte heterosporous or homosporous?

Polypodiophytes (ferns) also have homosporous (most ferns, including Equisetum - horsetails) and heterosporous (Salvinia - water ferns, Marsillea - clover ferns, and Azolla - mosquito ferns) groups. And why? This is more difficult to answer but heterospory seems to be a natural selection response to efficiency in reproduction.

Are there any plants that have a homosporous life history?

A homosporous life history occurs in nearly all bryophytes and in most pteridophytes (lower vascular plants). It is characterized by morphologically identical spores that germinate to produce bisexual (both male and female) gametophytes in pteridophytes but either bisexual or, more usually, unisexual… Extant homosporous plants include most ferns...
