Is a sporophyte or gametophyte embryo in a seed?
In a seed, it is the sporophyte embryo that is present. The sporophyte is the diploid generation that develops from the fertilization of gametes, while the gametophyte generation is typically reduced and dependent on the sporophyte in seed plants. Thus, the seed contains the developing sporophyte embryo, which will grow into the mature plant.
What happens to the prothallus as the embryo transforms into the sporophyte?
As the embryo develops into the sporophyte, the prothallus, which is the gametophyte stage of ferns, begins to degenerate. The sporophyte, which is the diploid generation, relies on the prothallus for initial nutrients and support before it becomes independent. Eventually, the prothallus will die off as the mature sporophyte establishes itself and starts to photosynthesize and grow on its own. Thus, the prothallus serves a temporary role in the life cycle of ferns.
Does the fertilized egg in an ovule become the zygote of a new sporophyte?
Yes, the fertilized egg within an ovule develops into a zygote, which is the initial cell of a new sporophyte generation in plants. Following fertilization, the zygote undergoes a series of divisions and developmental processes to form an embryo, which will eventually grow into a mature sporophyte. This process is part of the plant life cycle, which alternates between the sporophyte and gametophyte generations.
What generation is dominant in both gymnosperms and angiosperms?
The dominant generation in gymnosperms is the sporophyte generation, while in angiosperms it is also the sporophyte generation. The sporophyte generation produces the structures that we commonly recognize as trees, shrubs, and flowers in plants.

Does the gametophyte of ferns depends on sporophyte generation?
The sporophyte of a fern, destined to grow to be magnitudes larger than the prothallium, destroys the prothallium as it grows.
How does a moss sporophyte acquire nutrients in its environment?
A moss sporophyte acquires nutrients through its connection to the gametophyte, which provides it with water and nutrients through a structure called the seta. This allows the sporophyte to grow and develop in its environment.
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.
Why do gametophytes die after the sporophyte starts to grow?
The gametophyte is responsible for producing gametes, both male and female. When a male gamete fertilizes the female gamete, a zygote, or fertilized cell is created. This zygote matures and grows (through mitosis) into a sporophyte. At this point, the gametophyte has already done its job, and is not needed. Therefore it dies. The sporophyte releases spores, which eventually develop into gametophytes, and the cycle restarts.

What are two parts of a sporophyte fern and frond?
Either a Spore or Sori The Rhizome is an underground stem that they grow from. Hope I helped!
Gametophyte and sporophyte?
Gametophyte-haploid Sporophyte-diploid
What is a zoosopore?
Flaggelated asexual spores produced by a protist or early diverging fungi. A zoospore escapes the zygote of an adult diploid sporophyte in an aquatic enviornment, settles, and then uses mitosis to grow into a haploid adult algae or fungi know as a gametophye which produces sexual gametes that fuse together and grow into a diploid sporophyte through meiosis.
