What carries sperm in flowering plants?
The male reproductive tract carries sperm. Sperm are produced in the testes and are transported through the reproductive ducts. These ducts include the epididymis, vas deferens, ejaculatory duct and urethra. The reproductive glands produce secretions that become part of semen, the fluid that is ejaculated from the urethra.
Why dont the sperm nuclei of the male gametophyte of flowering plants have flagella?
During pollination, the sperm of the male gametophyte are not flagellated because they generally do not move. They rely on the growth of a pollen tube to deliver them to the egg cell.
What are the gametes of plants?
Flowering plants have gametes, which are the haploid sex cells. The sperm (male gamete) are found in the pollen on top of the anther. The eggs (female gamete) are located deep in a ovule usually in the center of the flower. Some flowers "self-pollinate" and others must have help from pollinators, such as bees, to get the sperm to the egg for the production of seeds.
What are two main types of gametes?
the female egg and male sperm.
The male reproductive structure of nonvascular plants is called?
The female gametophyte structure that produces eggs in nonvascular plants are called archegonia. The male structure that produces sperm are called antheridia. A gametophyte is the part of the plant that is responsible for creating gametes AKA sexual reproductive cell (sperm or egg). A nonvascular plant is a plant that isn't capable of transporting water and nutrients throughout itself very far because it lacks the proper vessels and veins for the transport. This causes these plants to be small in size so the plant doesn't have to transport the water and nutrients very far.
The pollen grain replaces what structure in the life cycle of seedless plants?
"Pollination is the transfer of the pollen grain from the anther to the stigma, where the pollen grain germinates, and becomes the mature male gametophyte." Source= Inquiry into Life Lab Manual. Therefore, the answer may be the mature male gametophyte...OR that it replaces a males sperm, depending on what your teacher is looking for. Hope this helps
Do nonvascular plants and seedless vascular plants have swimming sperm?
No.
What is true of both nonvascular plants and seedless vascular plants?
Both have swimming sperm.
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.
Do sperm swim to the eggs on fungi plants?
Sperm do not swim to eggs on plants like fungi. In fungi, sexual reproduction usually involves the fusion of specialized reproductive cells called gametes, which come into contact through proximity rather than active swimming.
In seed plants the sperm make it to the egg via?
By swimming in watery fluid through the neck of archegonium the sperm reaches to the egg in seedless plants.

Do ferns have swimming sperm?
yes.
How can a sperm influence the menstrual cycle?
Sperm does not directly influence the menstrual cycle. The menstrual cycle is regulated by hormones like estrogen and progesterone that are produced by the ovaries. Sperm's role is to fertilize an egg if present, which can lead to pregnancy but does not impact the regularity of the menstrual cycle.
What normal feature does the sperm cell have?
they have long tails for swimming and heads to get into the ovum
What part of the life cycle does a pollen grain represent?
A pollen grain represents the male reproductive cell in the life cycle of a plant. It is the structure responsible for fertilizing the ovules and producing seeds.
What is an animal cell that uses a special structure for swimming?
Sperm
