Question

What is an example of pteridophyte?

Answer 1

Hint: A pteridophyte is a vascular plant that disperses spores and has xylem and phloem. Pteridophytes are often referred to as "cryptogams," meaning that their means of reproduction are secret, since they do not grow flowers or seeds.

Complete answer:
A pteridophyte is a vascular plant that disperses spores and has xylem and phloem. Pteridophytes are often referred to as "cryptogams," meaning that their means of reproduction are secret, since they do not grow flowers or seeds.
Pteridophytes thrive in cold, humid, shade environments.
The primary plant body is a sporophyte, which is divided into true roots, stems, and leaves, as well as vascular tissues that are well-differentiated.
Sporophytes have sporangia that are protected by sporophylls, which are leaf-like appendages that may shape distinct compact structures called strobili or cones.
The sporangia create spores in spore mother cells by meiosis, and the spores germinate to produce thalloid gametophytes named
Male and female reproductive organs, such as antheridia and archegonia, are found in gametophytes.
The movement of antherozoids to the mouth of the archegonium requires water, and the fusion of the male gamete with the egg in the archegonium results in the development of zygote.
The zygote develops a multicellular, well-differentiated sporophyte, which is the pteridophytes' dominant process.
Plants that contain homosporous spores are considered homosporous, and those that produce dissimilar spores, such as micro and macro pores, are called heterosporous. For example, Selaginella and Salvinia produce micro and macro pores.
The female gametophytes are responsible for the growth of the zygotes into young embryos.
Ferns, horsetails (often treated as ferns), and lycophytes (clubmosses, spikemosses, and quillworts) are all pteridophytes.
