Are sperm protected from drying out in the fern cycle?
no
What is time travel of the sperm cell to the ovary?
Sperm cells do not time travel to the ovary. They travel through the female reproductive tract via the cervix, uterus, and fallopian tubes to reach the egg for fertilization. Time travel is a concept found in science fiction and is not possible in reality.
What do new fern plants form?
New fern plants grow out of spores into gametophytes. There are male and female gametophytes that produce gametes respectively. Because ferns are pteridophyta, they lack sporopollenin to provide transportation of sperm in the absence of water. In the presence of water, the antheridia of the gametophytes release sperm, which travel through the water and swim into the archegonia of other gametophytes, where the egg and sperm fuse together to form a zygote. This zygote grows into a sporophyte, which is what you typically see and recognize as a fern.
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.
What direction do sperm travel?

What is tiny heart-shaped part of a fern that produces both sperm and eggs?
sporophyte
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.
How does water travel throughout a Fern?

In where the red fern grows where did the boy have to travel to pick up his purchase?
The boy in "Where the Red Fern Grows" had to travel to Tahlequah, Oklahoma to pick up his purchase of two coonhound puppies.
What is the significance of chemotaxis to fern reproduction?
Chemotaxis plays a crucial role in fern reproduction by guiding the sperm towards the egg for fertilization. It helps ensure successful mating by enabling the sperm to navigate through the water to reach the egg. This process increases the chances of successful fertilization and subsequent plant development.
The passageway for sperm to exit the body from the epididymis is?
