What is the simple definition of sporophyte?
Table of Contents
Definition of sporophyte : the diploid multicellular individual or generation of a plant with alternation of generations that begins from a diploid zygote and produces haploid spores by meiotic division — compare gametophyte.
What is the purpose of the sporophyte stage?
The basic function of the sporophyte is to create spores – that much is known already. The spores, in turn, produce the gametophytes that give rise to the male and female gametes through the process of meiosis. Meiosis is the type of cell division that reduces the number of chromosomes in half.
What is the sporophyte stage?
A sporophyte (/ˈspɔːr. əˌfaɪt/) is the diploid multicellular stage in the life cycle of a plant or alga. It develops from the zygote produced when a haploid egg cell is fertilized by a haploid sperm and each sporophyte cell therefore has a double set of chromosomes, one set from each parent.
What is Sporophytic and Gametophytic?
In plants, alternation of generations exists, where the members have haploid and diploid phases. The plant’s haploid phase is called gametophyte and the diploid phase is called the sporophyte.

What is Sporophytic self incompatibility?
Sporophytic self-incompatibility (SSI) is a self-pollen recognition system that enforces outcrossing in plants. Recognition in SSI systems is typically controlled by a complex locus (S-locus) with separate genes that determine pollen and stigma specificity.
How is gametophyte different from sporophyte?
Gametophytes are haploid (n) and have a single set of chromosomes, whereas Sporophytes are diploid (2n), i.e., they have two sets of chromosomes.
Which group plant body is Sporophytic but with out flower?
Seedless vascular plants are plants that contain vascular tissue, but do not produce flowers or seeds. In seedless vascular plants, such as ferns and horsetails, the plants reproduce using haploid, unicellular spores instead of seeds.
Which of the following structure do not represents Sporophytic generation in flowering plants?
So, the correct answer is ‘Endosperm’
What is sporophyte in biology?
Sporophyte. 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. The sexual phase is the gametophyte.
What is the difference between sporophyte and sexual phase?
The sexual phase is the gametophyte. In the sporophyte phase a diploid (having two sets of chromosomes) plant body grows and eventually produces spores through meiosis. These spores divide mitotically to produce haploid (having a single set of chromosomes) gamete-producing bodies called gametophytes.
What is a spore-forming organism?
n. The diploid spore-producing phase in the life cycle of a plant that exhibits alternation of generations. the form of a plant in the alternation of generations that produces asexual spores. In plants, fungi, and certain algae, the individual organism or generation of organisms that produces spores.
What are the sporophytes of conifers?
The sporophytes of all conifers are trees or shrubs. They have a life span that ranges from a few decades to more than 5,000 years. The…. In the sporophyte phase a diploid (having two sets of chromosomes) plant body grows and eventually produces spores through meiosis.
