Bryophytes also need a moist environment to reproduce . Their flagellated sperm must swim through water to reach the egg. So mosses and liverworts are restricted to moist habitats.
Why do ferns live in wet areas?
Ferns must live in moist environments because their reproductive processes are dependent on water . Ferns are seedless, vascular plants and spore-producing specimens that are important to woodland and wetland environments. At this phase, the fern consists of large compound leaves, or fronds.
Why do mosses live in moist damp areas?
Mosses can only survive in the water as it is lacking a vascular system , unlike other plants. So mosses can’t transport water and mineral to its various parts instead they rely on osmosis to allow a cell to cell transport, so being in damp areas would be beneficial for them.
Why must mosses and ferns live in moist environments quizlet?
Why do ferns, club mosses and horsetails need a moist environment? because the plants release spores into their surroundings, where they grown into gametophytes . When the gametophytes produce the egg and sperm cells, there must be enough water for the sperm to swim to the egg.
Why are most ferns confined to wet areas 11?
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. ...
What is the dominant generation in ferns?
The dominant part of the life cycle, i.e., the plant that is recognized as a fern, represents the sporophyte generation . The gametophyte generation includes the phase of the life cycle between the formation of spores by meiosis and fertilization and formation of the zygote.
Is moss always wet?
Although some mosses like to be really wet consistently , others may prefer to dry out. A considerable number of mosses will not tolerate constantly “wet feet.” In contrast, aquatic mosses can actually live under water. ... Mosses absorb moisture and nutrients through their leaves.
Does moss eat dust?
Since mosses “eat” dust particles in such minute quantities , fertilizers could actually hamper moss growth. Even organic fertilizers might provide too much of a particular nutrient or micronutrient. ... Further, insects inhabiting mosses do not eat them or cause any significant damage.
Does moss need sunlight?
Some mosses can survive in full sun , though most prefer shade. Moss can grow on any type of soil because their shallow roots simply hold the moss there without drawing nutrients from the soil. They get some nutrients from water, but mostly they make their own food through photosynthesis.
Why must mosses live in moist environments group of answer choices?
Nonvascular – Mosses – don’t have vascular tissue (xylem/phloem), so they’re very short. Need to live in damp places so sperm can swim to egg . ... Also need to live in damp places so sperm can swim to egg. Also reproduce by spores, which are produced in the sori on the underside of the frond.
Are Sporophytes haploid?
In the sporophyte phase a diploid (having two sets of chromosomes) plant body grows and eventually produces spores through meiosis. These spores divide mitotically to produce haploid (having a single set of chromosomes) gamete-producing bodies called gametophytes.
Why are ferns used around homes and businesses?
natural weed killing . cleaning. repelling insects.
Which fern is Woody?
The fronds of tree ferns also exhibit circinate vernation, meaning the young fronds emerge in coils that uncurl as they grow. Unlike flowering plants, tree ferns do not form new woody tissue in their trunk as they grow. Rather, the trunk is supported by a fibrous mass of roots that expands as the tree fern grows.
What is the life cycle of Pteridophytes?
The life cycle of pteridophytes is a continuous reproductive process that is dominated by the sporophyte (sexual) stage of the alternation of generations. Fern spores are catapulted into the air, and the spores develop into heart-shaped haploid gametophytes that contain both male and female sex organs.
What is the fern life cycle?
The life cycle of the fern has two different stages; sporophyte, which releases spores, and gametophyte, which releases gametes . Gametophyte plants are haploid, sporophyte plants diploid. This type of life cycle is called alternation of generations.
Which generation in the life cycle of ferns lacks vascular tissue?
The fern gametophyte is a small (approximately 5 mm), bisexual, heart-shaped plant called a prothallus. The prothallus is haploid, since it grew from a spore which had been formed by meiosis. It does not have any vascular tissue and uses small rhizoids to anchor it to the ground.
