What role does the dominant generation play in the life cycle of ferns?
The dominant generation in the life cycle of ferns is the sporophyte, which is the plant that produces spores. The sporophyte is the visible, leafy plant that we typically think of as a fern. It plays a crucial role in reproduction by producing spores that develop into the gametophyte, which is a smaller, less visible plant that produces eggs and sperm. The gametophyte then fertilizes and develops into a new sporophyte, completing the life cycle of ferns.
Which structure produces sperm?
The structure that produces sperm is the testes, which are located in the scrotum. Sperm are produced within the seminiferous tubules of the testes through a process called spermatogenesis.
What is the dominant generation in ferns and how does it contribute to the reproductive cycle of these plants?
The dominant generation in ferns is the sporophyte, which is the larger and more visible stage of the plant. The sporophyte produces spores through meiosis, which then develop into the gametophyte stage. The gametophyte produces gametes (eggs and sperm) through mitosis, which then fuse to form a new sporophyte, completing the reproductive cycle of ferns.
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.
Does gametophyte generation depends on sporophyte generation in ferns?
Yes, in ferns, the sporophyte generation is dominant and produces spores that give rise to the gametophyte generation. The gametophyte generation is a smaller, independent stage that produces gametes (sperm and egg) which fuse during fertilization to form the sporophyte generation.
Gametogenesis that produces sperm is called?
Gametogenesis that produces sperm is called spermatogenesis. This occurs in the testes.
What produces egg and sperm in life of plant?
gametophyte
How does the sporophyte generation of a plant differ from a gametophyte generation?
In most plants, the sporophyte generation is dominant. In fern, for example, the fern itself is the sporophyte. This organism produces spores that fall to the substrate below and grow into a separate organism called a gametophyte. The gametophyte produces sperm and eggs in order to produce a new sporophyte which grows out of the gametophyte's body, destroying it. It is important to note that the gametophyte is haploid and the sporophyte is dploid.

How are sperm and egg produced by the haploid generation of a plant formed?
you people are ****** a'f -.-
What is the difference between the 2 generations of a moss plant?
Mosses have a life cycle with two very different stages. One generation looks plantlike. The plantlike generation carries out sexual reproduction. it makes egg and sperm cells that join to produce a new moss plant. Then the other generation begins. This generation looks like a stalk that grows out of the leaf like part of the moss. This generation carries out asexual reproduction, in which a new plant is produced without the joining of a sperm and an egg cell. The stalk produces spores. A spore is a structure that contains cells that can grow into a new plant without joining with other cells.
What produces eggs and sperm cells during the life cycle of a plant?
gametophytes
What are plant sperm cells called?
Plant sperm cells are called male gametes or sperm cells. They are produced in the anther of a flower through a process called pollenation.
Which structure produces sperm?
The structure that produces sperm is the testes, which are located in the scrotum. Sperm are produced within the seminiferous tubules of the testes through a process called spermatogenesis.
What are reproductive cells called?
Reproductive cells are called gametes. In males, the gametes are called sperm and in females, the gametes are called eggs.
