What is the difference between antheridia and archegonia?
Antheridia are male reproductive structures that produce sperm cells, while archegonia are female reproductive structures that house egg cells. Antheridia are typically smaller and simpler in structure compared to archegonia. Both structures are commonly found in plants like mosses and ferns.
What are the gametes produced in nonvascular plants?
These two other answers are straight cap. The correct answer is Antheridium for A+ people.
Which generation of mosses are the photosynthetic?
The first generation of mosses starts with germination of spores to develop into gametophyte. The male and female gametophytes produce anthridia and archegonia. Motile antherozoids are released from anthridia and make their way to archegonia through water. The egg inside archegonium is fertilized to form the zygote. The zygote develops into a sporophyte, which remain dependent on the gametophyte.
Are Antheridia present in conifers?
Yes, antheridia are present in conifers. They are the male reproductive structures that produce sperm cells. In conifers, antheridia are typically found within the male cones of the tree.
What are the 4 parts of avascular plant?
The four parts of avascular plants are the gametophyte, sporophyte, rhizoids, and sporangia. The gametophyte is the haploid stage that produces gametes, while the sporophyte is the diploid stage that produces spores. Rhizoids are root-like structures that anchor the plant and absorb water, while sporangia are structures that produce and release spores for reproduction.
Structure that holds antheridia and archegonia in ferns?
The structure that holds antheridia and archegonia in ferns is called the gametophyte. It is a small, heart-shaped structure that develops on the underside of the fern frond. Antheridia produce sperm cells, while archegonia produce egg cells for sexual reproduction in ferns.
What is the difference between antheridia and archegonia?
Antheridia are male reproductive structures that produce sperm cells, while archegonia are female reproductive structures that house egg cells. Antheridia are typically smaller and simpler in structure compared to archegonia. Both structures are commonly found in plants like mosses and ferns.

Structures in plants that produce the gametes are called?
Structures in plants that produce gametes are called gametangia. In ferns and mosses, the male gametangia are called antheridia, while the female gametangia are called archegonia. In flowering plants, the male gametangia are the pollen grains produced in the anthers, and the female gametangia are the ovules contained in the ovary.
What important structures do gametophytes produce?
Gametophytes typically produce gametes through the process of mitosis. These gametes are necessary for sexual reproduction as they unite to form a zygote, which develops into the sporophyte generation. Additionally, some gametophytes also produce specialized structures such as antheridia and archegonia that house and protect the gametes.
Gametophytes have gamete-producing organs called?
Angiosperms produce seeds in layers of tissue called fruit.
Which generation of mosses are the photosynthetic?
The first generation of mosses starts with germination of spores to develop into gametophyte. The male and female gametophytes produce anthridia and archegonia. Motile antherozoids are released from anthridia and make their way to archegonia through water. The egg inside archegonium is fertilized to form the zygote. The zygote develops into a sporophyte, which remain dependent on the gametophyte.
What is a structure in seedless plants that produces sperm?
Antheridia are structures in seedless plants that produce sperm. They are typically found on the gametophyte generation of plants like ferns and mosses. Within the antheridia, sperm cells are produced through a process of spermatogenesis.
Where do you Find antheridium?
Antheridia are found in non-flowering plants, particularly in bryophytes (like mosses and liverworts) and certain ferns. They are typically located on the male gametophyte, where they produce sperm cells. Antheridia can be found in moist environments, as they require water for sperm motility during reproduction.
Mosses that reproduce with gametes are?
haploid. They produce male and female gametes through mitosis in specialized structures called antheridia (male) and archegonia (female). When these gametes fuse, they form a diploid zygote that develops into a sporophyte.
True about the life cycle of mosses?
The life cycle of moss is as follows:Sperm and egg are fertilized and form a zygote. The zygote transforms into a gametophyte and then a sporophyte. It undergoes meiosis and grows to form moss.
What advance characteristic of sub-phylum Filicinophyta?
Ferns always have the following characteristics. (1)Plant bodies are better developed than bryophytes. Differentiation is obvious. Plant bodies possess the vegetative organs, as leaves and stems. But roots are still called rhizoids.(2)In their alternation of generations, the asexual generation predominate. The plant bodies in asexual generation are called sporophytes. The sizes of sporophytes range from 40 cm to 100 cm in height.(3)Sporophytes can produce asexual spores for the production of the gametophytes. Gametophytes can be free-living and possess chloroplasts for photosynthesis. Others may be parasitic in the sporophytes. For living forms, the gametophytes are called prothallus. A thallus is thin and have several layers of cells in thickness. So, they cannot resist direct sunlight.(4)Gametophytes can produce antheridia and archegonia. Antheridia produce antherozoids, the male gametes. Archegonia produce ova, the female gametes.(5)The primitive forms produce only one type of asexual spore. After germination, this unit type of asexual spore can produce both antheridia and archegonia. So, this type of plants are called homosporous. The advance form would produce two types of asexual spores, the megaspores and microspores. Megaspores can germinate to produce female gametophytes. Microspores can germinate to produce male gametophytes. Then, they are called heterospores. -ahang-
