What type of reproductive cells are produced by the sporophyte?

Specialized cells of the sporophyte will undergo meiosis and produce haploid spores. The spores will develop into the gametophytes (Figure 7. 2 c).

Which reproductive cells are produced by the gametophyte?

Specialized cells of the gametophyte undergo mitosis to produce sperm and egg cells (1n), which combine in fertilization to make a zygote (2n).

What is produced by the sporophyte generation?

The sporophyte produces spores (hence the name) by meiosis, a process also known as “reduction division” that reduces the number of chromosomes in each spore mother cell by half. The resulting meiospores develop into a gametophyte.

What are the reproductive cells of a plant?

The male sex cell in a plant, or more specifically the part that bears pollen, is called a stamen and consists of an anther and a filament. The female part, which receives pollen grains, is called a pistil and includes an ovary (easy enough to remember, since human females have these as well), a stigma and a style.

Which plants reproduce by spores?

Plants that reproduce by spores Ferns, mosses, liverworts and green algae are all plants that have spores. Spore plants have a different life cycle.

Do Sporophytes produce gametes?

Diploid sporophyte cells undergo meiosis to produce haploid spores. Each spore goes through mitotic divisions to yield a multicellular, haploid gametophyte. Mitotic divisions within the gametophyte are required to produce the gametes. The diploid sporophyte results from the fusion of two gametes.

Is pollen a sporophyte or gametophyte?

Pollen grains are the male gametophytes in flowering plants. Inside the pollen grain, the microspore divides to form two cells, a tube cell and a cell that will act as the sperm.

What are some examples of the sporophyte generation?

Examples of Sporophyte

• Bryophytes. Bryophytes are comprised of mosses, liverworts, and hornworts.
• Algae. Green, red, and brown algae follow alternation of genes from gametophyte to sporophyte generation.
• Horsetail.
• Ferns.
• Club mosses.
• Gymnosperm.
• Angiosperms.
• What is a sporophyte?

What is an example of a sporophyte?

An example of sporophyte is a mature fern plant. Among organisms which display an alternation of generations (such as plants, fungi, and certain algae), the individual diploid organism that produces spores. A sporophyte develops from an embryo resulting from the union of two gametes.

What is gametophyte and sporophyte?

In plants, alternation of generations exists, where the members have haploid and diploid phases. The plant’s haploid phase is called gametophyte and the diploid phase is called the sporophyte.

What is the sporophyte in angiosperms?

The angiosperm life cycle consists of a sporophyte phase and a gametophyte phase. The cells of a sporophyte body have a full complement of chromosomes (i.e., the cells are diploid, or 2n); the sporophyte is the typical plant body that we see when we look at an angiosperm.

Which of the following reproduces by spore formation?

The correct answer is Rhizopus. Spore formation is a method of asexual reproduction. Plants like ferns, moss, fungi reproduce by this method. Spores are unicellular reproductive bodies present in a sac called sporangia.

How do ferns and mosses reproduce?

So the correct answer is: Fern and Moss reproduce by spores.

Are angiosperms sporophyte or gametophyte?

Is ovary a sporophyte or a gametophyte?

They consist of highly specialized male and female reproductive organs. Flowers produce spores that develop into gametophytes. Male gametophytes consist of just a few cells within a pollen grain and produce sperm. Female gametophytes produce eggs inside the ovaries of flowers.

What is the role of the sporophyte?

Sporophyte is the diploid phase in the life cycle of a plant. It produces spores by meiosis that give rise to haploid gametophytes.

What part of a plant is sporophyte?

In vascular seed-bearing plants, the sporophyte is made of the entire body of the plant except for the embryo sac and pollen.

Do sporophytes produce gametes?

Which plants are reproduced by spores?

Plants that reproduce by spores Ferns, mosses, liverworts and green algae are all plants that have spores.

Which does not reproduce by spore formation?

Amoeba, Paramaecuim, Plasmodium, Yeast, Hydra spyrogyra are not produced by spore formation.
