Asexually it reproduces by fragmentation. The vegetative filament breaks into smaller fragments. Each fragment grows and produces a longer filament. Sexual reproduction occurs by a process known as conjugation, in which cells of two filaments lying side by side are joined by outgrowths called conjugation tubes.Ferns do not flower but reproduce sexually from spores. There are two distinct stages of the fern life cycle. Mature plants produce spores on the underside of the leaves.Sporophyte ferns have two methods of asexual reproduction. One is by vegetative cloning, branching off of the root-like underground stem, or rhizome, often forming large, genetically uniform colonies. The second form of asexual reproduction occurs by spores.

Does Spirogyra reproduce by spore formation?
Spirogyra and Fucus follow this type of reproduction. (c) Spore formation: Some plants contain spores as reproductive bodies, which are surrounded by a thick wall. When there is a favourable condition for germination, these spores bursts out of thick wall, multiplies and grows into new plants.
Does Spirogyra reproduce by fission?
In Spirogyra, asexual reproduction takes place by fragmentation.
Which type of reproduction takes place in spirogyra?
Spirogyra species can reproduce both sexually and asexually. Asexual, or vegetative, reproduction occurs by simple fragmentation of the filaments. Sexual reproduction occurs by a process known as conjugation, in which cells of two filaments lying side by side are joined by outgrowths called conjugation tubes.
How do ferns reproduce answer?
Answer and Explanation: Ferns reproduce by producing and releasing spores in the sporophyte generation. Spores are formed from the sporangia of the fern, which are located…
How do ferns and mosses reproduce?
To reproduce sexually, mosses and ferns produce sperm and eggs. The motile sperm must be able to swim through water to reach and fertilize the eggs, which is why most mosses and ferns live in damp habitats. Even in the absence of rainfall, moisture-laden fog or morning dew produce enough water to accomplish this task.

Which plants reproduce asexually?
Plants such as ferns, liverworts, and mosses can reproduce asexually via gemmae—which are small disks of green tissue that grow inside special cups. When mature, gemmae break off and scatter away from the parent plant.
Which plant reproduces asexually by spore formation method?
Fungi like Rhizopus, Mucor, etc., are examples of spore formation. This is a common bread mould plant or rhizopus fungus. It reproduces by forming spores. Regeneration is an asexual method of reproduction.
How does Spirogyra reproduce fragmentation?
The process of asexual reproduction in Spirogyra is known as fragmentation, where the body of spirogyra when matures will get break into many smaller pieces or fragments due to strong water current. These different pieces will later grow into new individuals.
What is the mode of reproduction in fungi ferns and mosses?
Explanation. The method of asexual reproduction found in fungus, moss and fern is spore formation. The parent plant releases spores into the air. These spores are covered by a protective coat to withstand unfavorable conditions.

What reproduces spore formation?
Rhizopus, mushroom etc., reproduce by spore formation.
Is Spirogyra reproduce by budding?
The answer is False. Spirogyra reproduces by asexual reproduction through fragmentation.
Does Spirogyra have Zoospores?
No zoospores or cells with flagella are produced by Spirogyra. All algae are not filamentous. Thus, the correct answer is option C.
How is asexual reproduction in Spirogyra?
Spirogyra reproduces asexually by fragmentation and sexually by conjugation. In the fragmentation method, Spirogyra breaks into two or more segments and each segment forms a new organism.
What is the name of asexual reproduction method in I Spirogyra?
Asexual method of reproduction in Spirogyra is fragmentation, while in Leishmania is binary fission. Explanation: In Spirogyra during fragmentation, the broken fragment or piece of an organism grows into a new organism. Fragmentation type of asexual reproduction takes place in multicellular organisms.
How does Spirogyra grow?
In spring Spirogyra grows under water, but when there is enough sunlight and warmth they produce large amounts of oxygen, adhering as bubbles between the tangled filaments. The filamentous masses come to the surface and become visible as slimy green mats.
What part of the fern plants helps them to reproduce?
Ferns reproduce asexually by their modified stems, which are called rhizomes. Rhizomes spread just above or below the soil surface where they form roots on their undersides and new plants above.
Where do ferns produce their spores?
On the underside of the fronds are sporangia. Within the sporangia are spore producing cells called sporogenous cells. These cells undergo meiosis to form haploid spores. The spores on most ferns are the same size and perform the same function.
How ferns release and disperse spores?
Fern Dispersal Method
The dispersal of spores in ferns takes place through the annulus on the plant – a cluster of cells arranged in an arc or ring on the sporangium. Under dry conditions, the water in the annulus plant cells evaporates, causing the cell walls to peel back and expose the sporangium.

How do mosses and ferns reproduce one line answer?
Answer: Ferns and mosses reproduce by releasing millions of spores through the air. The spores are fed eggs and are spread through the environment by wind.
Does ferns and mosses reproduce by seeds or spores?
Plants such as ferns and mosses are called nonflowering plants and produce spores instead of seeds. There is also another group called the Fungi, that include mushrooms, and these also reproduce by spores.
