What is required for the transport of sperm in mosses and ferns?
The correct answer is Moisture . The bryophytes are flowerless primitive plants found in damp and shady places. The sperms of moss are released in the ambient moisture and these sperms are flagellated cells that swim in the moisture.
How do mosses and ferns carry sperm?
The sperm swims to the archegonia through a thin film of water, drawn by a chemical attractant produced by the female plant, then swims down the neck of the archegonia to the egg. A good morning dew is more than sufficient water for the sperm to swim. Once the sperm enters the archegonia, it fuses with the egg.
How do ferns move their sperm?
At sexual maturity, the male structures release sperm that swim through the film of water of the moist habitat to fertilize the egg in the female structure. Horsetail gametophyte processes are similar, but they look more like little green ragged mounds.
How do moss and fern plants reproduce?
Fungi, moss and fern all three reproduce by a common method of asexual reproduction which is called spore formation. Spore formation occurs in non-flowering plants. Spore are minute structures that are produced by the parent plant and are released into the air.
What do both mosses and ferns require for fertilization to occur?
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.
How does fertilization occur in moss and ferns?
Their life cycle is very simple, and they have asexual reproduction by spores. Fertilization occurs when spores are released into the atmosphere and land on another plant, leading to the production of new mosses. Fertilization occurs in the moss life cycle when sperm from a male and egg from a female join together.
What do mosses and ferns both required for reproduction?
Fungi, moss and fern all three reproduce by a common method of asexual reproduction which is called spore formation. Spore formation occurs in non-flowering plants. Spore are minute structures that are produced by the parent plant and are released into the air.
What is required for fern fertilization?
Fertilization. Ferns are relatively light feeders compared to many other foliage plants. They prefer a balanced fertilizer, such as 20-10-20 or 20-20-20, with micronutrients applied at approximately 200 ppm nitrogen. Too much nitrogen can cause tip burn on the roots and leaves if the plant becomes dry.Jul 15, 2010
What do moss and ferns have in common?
Answer and Explanation: Mosses and ferns are alike because they are both non-flowering plants and don't produce seeds either. They are called gymnosperms. Instead, they produce many tiny spores into the air that spread and grow other mosses and ferns.
Do ferns require water for sperm transport?
Ferns require water to enable the movement of the sperm to reach the egg. A zygote is a combination of genetic material from both the egg and sperm and contains a complete set of DNA to form a new fern plant.Sep 24, 2010
Do ferns need water to reproduce?
The sperm needs to swim through water in order to get to the eggs. The eggs are housed or maintained in the gametophyte. And that dependence on water is why ferns are so often linked to wet habitats.Sep 24, 2010
