What is a land plant that produces flagellated sperm and has a sporophyte dominated life cycle?
A land plant that fits this description is a fern. Ferns have flagellated sperm that require water for fertilization, and their life cycle is characterized by a dominant sporophyte stage. During fertilization, the sperm swim through water to reach the eggs on the archegonia of the female gametophyte.
What group of plants require water for sexual reproduction to occur?
Strictly speaking all plants, for without water plants die! However algae, bryophytes (mosses and liverworts) and pteridophytes (ferns) all have motile male gametes which require free water to swim through to the female gamete.
What does fertilization not require in most seed plants?
Fertilization in most seed plants does not require swimming sperm, as they are transported within pollen grains and delivered directly to the plant ovule for fertilization to occur. This eliminates the need for water as a medium for fertilization, unlike in non-seed plants or aquatic plants where swimming sperm are necessary to reach the egg.
When can mosses and ferns reproduce sexually?
Mosses and ferns reproduce sexually during their gametophyte stage, which is when they produce eggs and sperm. This typically occurs when conditions are favorable, such as when there is enough moisture for sperm to swim to the eggs for fertilization.
What are the characteristics of pterophytes?
Pterophytes or fern are the most diverse phylum of seedless plants, containing approximately 11000 species (in at least 17 families), about three quarters of which are found in the tropics. Leaves are diverse in size and shape; size varying from just 1cm to up to 5m in some tree ferns. The fronds are coiled and unfurl as the plant grows. Sporangia are often on the underside of leaves.
Do ferns require water for fertilization?
Yes, ferns require water for fertilization. Ferns reproduce by releasing spores into the environment, which need water to swim to a suitable location to germinate and grow into a new fern plant. Water is essential for the spores to move and establish new plants.
Do gymnosperms depend on water?
Yes, gymnosperms do not depend on water for fertilization like mosses or ferns do. They reproduce through the dispersal of pollen, which does not require water as a medium for transportation.
What you call seed producing plant?
It is called a seed plant, not to be confused with ferns and mosses whose gametes require water for fertilization. Seed plants can be either gymnosperms or angiosperms.Spermatophyte

Can ferns grow in water, or do they require soil to thrive?
Ferns can grow in water, but they typically thrive better in soil.
How vascular and deciduous plants require water fertilization?

What event in a fern's lifecycle requires water?
if your using Plato then the answer is D. the movement of sperm between plants.
Do bryophytes need water for fertilization?
Yes, bryophytes, like mosses and liverworts, require water for fertilization. This is because they rely on water to transport sperm from the male gametophyte to the female gametophyte for fertilization to occur.
Explain why ferns live in moist environments even though they have vascular tissue?
This is because the plants relese spores into their surroundings,where they grow into gametophytes. When the gametophtes produce egg cells and sperm cells,there must be enough water available for fertilization. hope my answes correct i too was searching for a long time to find the answer, but when i read again {looks like i found it} ;)
What life cycle components appear only in mosses and ferns?
The gametophyte generation is more prominent and independent in mosses and ferns compared to seed plants. Also, the sporophyte generation in mosses and ferns is not as prominent or long-lived as in seed plants. Finally, mosses and ferns rely on water for fertilization, a characteristic not seen in seed plants.
Do angiosperms require water for fertilization?
Yes Edited answer: No, only crptogames need water for fertilization. In higher plants like angiosperms, the gametes are non-motile and male gametes reach near the egg for fertilization with the help of pollen tube.
How is the mechanism for spore dispersal in ferns similar to that of bryophytes?
Both ferns and bryophytes rely on water for spore dispersal, though the mechanisms differ slightly. In ferns, mature spores are released from sporangia, often aided by wind or raindrops, while in bryophytes, spores are typically released from capsules that can open when wet, allowing for dispersal when conditions are right. Both groups produce lightweight spores that can be carried by air or water to suitable habitats for germination. Additionally, both rely on moist environments for successful reproduction, as their gametes require water for fertilization.
