What else can I help you with?
Do bryophytes need water for fertilization?
Yes, bryophytes, like mosses and liverworts, require water for fertilization. This is because they rely on water to transport sperm from the male gametophyte to the female gametophyte for fertilization to occur.
In flowering plant which of these becomes the female gametophyte?
The female gametophyte in a flowering plant is the embryo sac, which is formed within the ovule. It consists of seven cells, including the egg cell which is essential for fertilization to occur.
Do gametophytes produces seeds or pollen?
Gametophytes produce pollen, which is the male gametophyte. Seeds are produced by the fertilization of the female gametophyte by pollen.
Do gametes become gametophyte?
No, gametes do not become gametophytes. Gametes are reproductive cells that fuse during fertilization to form a zygote, which then develops into a multicellular organism called a gametophyte in plants. Gametes are only involved in the process of sexual reproduction, while gametophytes are part of the plant's life cycle.
Is the gametophyte not free living in bryophytes?
In bryophytes, the gametophyte is the dominant, free-living stage of the life cycle. It is the structure responsible for producing gametes and supporting fertilization. The gametophyte in bryophytes usually grows independently from the sporophyte, which is dependent on the gametophyte for nutrition and support.
During the life cycle of a plant gametophyte is to n as sporophyte is to?
During the life cycle of a plant, gametophyte is to n as sporophyte is to 2n. Gametophyte produces haploid gametes through mitosis, which fuse during fertilization to form a diploid zygote that develops into a sporophyte through mitosis.
What is the correct sequence of development in a flowering plant?
Pollination, fertilization, seed formation, seed germination
Do bryophytes need water for fertilization?
Yes, bryophytes, like mosses and liverworts, require water for fertilization. This is because they rely on water to transport sperm from the male gametophyte to the female gametophyte for fertilization to occur.

The female gametophyte in a flowering plant is the embryo sac, which is formed within the ovule. It consists of seven cells, including the egg cell which is essential for fertilization to occur.
What do gametophyte produce during a plant life cycle?
Gametophytes produce gametes (eggs and sperm) during the plant life cycle. These gametes will fuse during fertilization to form a zygote, which will develop into a new sporophyte plant.
Why must the plant which grows directly from the fern spore be wet?
The plant that grows directly from the fern spore, known as a gametophyte, must be wet because it requires water for fertilization. Ferns reproduce via a two-stage life cycle, and the sperm produced by the gametophyte needs to swim through water to reach the egg for successful fertilization. Additionally, moisture is essential for the gametophyte's growth and development, allowing it to absorb nutrients and carry out photosynthesis effectively.
What is a plant's lifecycle?
Depends on the plant: If it is a bryophyte, most of the time is spent in the gametophyte stage, until a sperm and egg fertilize. Once that happens the plant goes to the sporophyte stage, where spores are released to create more gametophytes. In seedless vascular plants, such as ferns, the plant still starts in the gametophyte (until fertilization) but the majority of the cycle is spent in the sporophyte stage (release spores to create new gametophytes). Seed bearing vascular plants have both stages at the same time but the sporophyte stage is not seen, all takes place in the flower.
In seed plants the structure that encloses the male gametophyte and transports it to another plant is called a?
In seed plants, the structure that encloses the male gametophyte and helps transport it to another plant is called pollen. Pollen grains contain the male gametophyte, which is the microgametophyte. When released from the anther of a flower, pollen can be carried by wind, insects, or other pollinators to reach the female reproductive structures of another plant, allowing for fertilization.
Do gametophytes produces seeds or pollen?
Gametophytes produce pollen, which is the male gametophyte. Seeds are produced by the fertilization of the female gametophyte by pollen.
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.
Do gametes become gametophyte?
No, gametes do not become gametophytes. Gametes are reproductive cells that fuse during fertilization to form a zygote, which then develops into a multicellular organism called a gametophyte in plants. Gametes are only involved in the process of sexual reproduction, while gametophytes are part of the plant's life cycle.
What are the two alternating phases of a plants life cycle?
The two alternating phases of a plant's life cycle are the reproductive phase (gametophyte) where plants produce gametes, and the vegetative phase (sporophyte) where plants grow and develop. The gametophyte phase produces gametes through meiosis, which then fuse during fertilization to form a new sporophyte plant.
