What is the function of the gametophyte?
A major function of the gametophyte generation is to produce haploid gametes. Fusion of the egg cell with the sperm cell gives rise to the sporophyte, thereby completing the life cycle (Raven et al., 1992). In many lower plants, gametophytes are the dominant and free-living generation.
What is the function of sporophyte and gametophyte?
The sporophyte's primary purpose is to produce spores. The spores, in turn, form gametophytes, which give birth to male and female gametes via the meiotic process. Following this step, the reproductive cells are ready to be fertilised in order to generate the sporophyte, completing the cycle.

What is a sporophyte and gametophyte?
Plants have haploid and diploid phases in which the generation and alternation happen. The haploid phase of the plant is called the gametophyte and the diploid phase of the plant is known as the sporophyte. The sporophyte generates spore in the plants whereas the gametophyte generates the gametes in the plants.
What is a sporophyte in simple terms?
sporophyte, in plants and certain algae, the nonsexual phase (or an individual representing the phase) in the alternation of generations—a phenomenon in which two distinct phases occur in the life history of the organism, each phase producing the other.
What is the difference between a gametophyte and a sporophyte generation?
The sporophyte generation is represented by the asexual phase, while the gametophyte generation is represented by the sexual phase. Furthermore, sporophytes are diploid, meaning they have two sets of chromosomes. Gametophytes, on the other hand, are haploid and have only one set of chromosomes.
What do sporophytes and gametophytes produce?
However, mitotic division still follows meiosis in the sporophyte, resulting in a multicellular gametophyte, which produces eggs or sperm. All of this takes place in the the organ that characterizes the angiosperms: the flower.
What do Sporophytes produce?
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 cell does gametophyte produce?
Haploid to only one set of chromosomes in the cells and written as 'n'. The primary job of gametophyte is the production of Gametes. The produced gametes are the haploid reproductive cells, such as sperm and eggs.
What is the difference between the sporophyte and gametophyte generations?
The sporophyte generation is represented by the asexual phase, while the gametophyte generation is represented by the sexual phase. Furthermore, sporophytes are diploid, meaning they have two sets of chromosomes. Gametophytes, on the other hand, are haploid and have only one set of chromosomes.
What is the relationship between the sporophyte and gametophyte generations?
The sporophyte generation is dependent on the photosynthetic gametophyte for nutrition. Cells within the sporangium of the sporophyte undergo meiosis to produce male and female spores, respectively.
