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 is the dominant phase of an angiosperm life cycle?
The dominant phase of an angiosperm life cycle is the sporophyte phase. This is the phase where the plant is in its mature form, producing flowers and seeds through the process of sexual reproduction. The sporophyte phase is the main phase where growth and development occur in angiosperms.
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 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.
What is the main plant in gymnosperms?
When you see a pine tree, or a spruce, or a cone-bearing shrub, the "main plant" is a sporophyte

Which generation in seed plants is most obvious?
The sporophyte generation is the most obvious in seed plants. This generation is the dominant phase and is the one that is most readily visible in the form of the mature plant.
What is the function of a prothallium?
The prothallium is the gametophyte stage in the life cycle of ferns. Its main function is to produce gametes (eggs and sperm) through mitosis, which will eventually lead to fertilization and the formation of a new sporophyte plant.

What is the function of the amature plant?
The main function of the mature plant is to produce flowers for reproduction. These flowers contain the reproductive organs necessary for creating seeds. Additionally, mature plants are responsible for photosynthesis, using sunlight to produce energy for growth and survival.
What does it mean when a gametophyte is dominant over a dependent sporophyte?
The main plant body is gametophytic as in case of Bryophytes
Gametophyte and sporophyte?
Gametophyte-haploid Sporophyte-diploid
How have the sporophyte and gametophyte changed as plants have evolved?
The gametophyte has become smaller, and the sporophyte has become larger. To begin with main plant body was gametophytic and sporophyte was dependent on it. Later on, as the evolution progressed, both gametophyte and sporophyte became independent and ultimatly gametophyte became dependent on sporophyte.
