In a fern's life cycle when does fertilization occur?
Fertilization in a fern's life cycle occurs when sperm from the male gametophyte fertilizes an egg in the female gametophyte, usually happening after the sperm swims to the egg in a film of water.
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 is tiny heart-shaped part of a fern that produces both sperm and eggs?
sporophyte
Why are my fern leaves drying out?
Fern leaves may be drying out due to lack of humidity, excessive sunlight, or underwatering. Make sure to keep the soil consistently moist and provide a humid environment for your fern to thrive.
Explain the stages in the life cycle of a fern?
A fern's life cycle alternates between two distinct stages: the sporophyte and gametophyte. The sporophyte stage is the dominant phase, where it produces spores through meiosis. These spores germinate into tiny gametophytes, which produce eggs and sperm. Fertilization of the egg by the sperm results in a new sporophyte plant.
Why is my fern drying out and how can I prevent it from happening?
Your fern may be drying out due to lack of humidity, overexposure to sunlight, or underwatering. To prevent this, ensure your fern is placed in a humid environment, away from direct sunlight, and water it regularly to keep the soil moist but not waterlogged.
Where does a sperm travel via in a fern?
water
What is the dominant stage of the fern life cycle what is the relationship of the fern gametophyte and sporophyte?
in the life cycle of a fern, the dominant and recognizable stage is the diploid sporophyte. the the younger sporophyte grows from the gametophyte.
What does the gametophyte stage of a moss or fern life cycle produce?
The gametophyte stage of a moss or fern life cycle produces gametes (eggs and sperm) through mitosis. These gametes combine during fertilization to form a diploid zygote, which develops into the sporophyte stage.
Why do fern sperm have flagella?
Fern sperm have flagella to help them swim to reach and fertilize the egg. The flagella provide motility, enabling the sperm to move through the water and navigate towards the egg for successful fertilization.
How can I prevent my fern from drying out?
To prevent your fern from drying out, make sure to keep the soil consistently moist but not waterlogged. Place the fern in a location with indirect sunlight and high humidity. Mist the leaves regularly and consider using a pebble tray or humidifier to increase moisture levels. Additionally, avoid placing the fern near drafts or heating vents that can dry out the plant.
The life cycle of a fern has how many generations?
Just the one
