Why do bryophytes pteridophytes grow in moist and shady places?
Plants like bryophytes and pteridophytes are usually very delicate and cannot withstand sun rays. So they prefer growing in moist shady places. Moreover these plants reproduce by spore formation. ... Thus moist and humid places are appropriate for the growth of these plants.
Why are pteridophytes reliant on moist environments?
Like the bryophytes, ferns and fern allies are still restricted to moist habitats. Their flagellated sperm need a thin film of water to swim between the antheridium and the archegonium. And when the baby sporophyte grows up from the gametophyte, it is exposed to desiccation (drying up).
Which are mostly found in moist shady places?
Mosses and ferns are found in moist and shady places because both.
Which bryophytes grow in moist and shady areas attached to the substratum?
The liverworts grow usually in moist, shady habitats. The plant body of a liverwort is thalloid, the thallus is dorsiventral and closely appressed to the substrate. Gemmae are green, multicellular, asexual buds, which develop in small receptacles called gemma cups located on the thalli.
Why do mosses grow in moist areas?
Mosses are found in moist areas because they are non-vascular plants and must absorb their water. ... Since mosses are non-vascular, they are lacking these tissues, and therefore, they have no transport system. Instead, mosses must absorb their water directly from their environment.
Which of the following will grow better in moist and shady region *?
Answer: Mangrove is the one which is better in shady and moist region. Explanation: Mangrove plants are scrubs-like short trees with prop roots.
Why do ferns live in moist shady environments?
Mosses and ferns are found in moist and shady places because both require the presence of water for sexual reproduction. As fertilization takes place only in the presence of water, through motile antherozoids that swim to reach the archegonium.
Why are ferns found in moist places?
The movement of spores requires a thin film of water. This is the main reason for ferns living in a moist environment. Water helps the spore to travel from Antheridium to Archegonium. In fact, all types of ferns and other related species need some sort of moisture to reproduce and grow.
Why are most ferns confined to a wet areas?
Ferns ( pteridophytes) require cool, damp, shady places to grow. They require moisture for effective fertilisation of gametes. Requirement of water for such processes limits the spread of living pteridophytes to narrow geographical regions which are wet areas. ...
Why are Pteridophytes common in moist and damp areas?
Pteridophytes are more common in humid places because they depend on water for their gametes to fertilize one another. In humid environments, their reproduction is more intense and they proliferate.
Why do moss and ferns grow in shady areas?
Since mosses obtain all their nutrients from the air, these shade plants require almost nothing from the soil on which they rest &ndash nothing more than shade, acidic soil, and adequate amounts of moisture.
In which places Pteridophytes are found?
Pteridophytes are found in moist, shady and damp places. They are found in crevices of rocks, bogs and swamps, and tropical trees.
Which pattern of life cycle is exhibited in bryophytes and pteridophytes?
Bryophytes and pteridophytes show haplo-diplontic life cycle, i.e. alternation of generation between gametophyte, which is haploid and sporophyte, which is diploid.
What is Prothallus with reference to pteridophytes?
A prothallus, or prothallium, (from Latin pro = forwards and Greek θαλλος (thallos) = twig) is usually the gametophyte stage in the life of a fern or other pteridophyte. Occasionally the term is also used to describe the young gametophyte of a liverwort or peat moss as well.
Why are mosses considered great ecological importance?
Mosses along with lichens are the first organisms to colonise rocks and hence, are of great ecological importance. They decompose rocks making the substrate suitable for the growth of higher plants. Since mosses form dense mats on the soil, they reduce the impact of falling rain and prevent soil erosion.
