What is a sporophyte kid definition?

A sporophyte is a multicellular diploid generation found in plants and algae that undergo alternation of generations. It produces haploid spores that develop into a gametophyte. The gametophyte then makes gametes that fuse and grow into a sporophyte. In many plants, the sporophyte generation is the dominant generation.

What is sporophyte explain with example?

The definition of a sporophyte is a mature phase in the life cycle of plants and some algae that produce spores. An example of sporophyte is a mature fern plant.

What is meant by sporophyte and gametophyte?

Both Gametophyte and Sporophyte are the two Generations of a plant. Gametophyte: Gameto means gametes and phyte means plants. The generation of plants that forms gametes is called gametophyte. Sporophyte: Sporo means spores and phyte means plants. The generation of plants that produce spores is called sporophyte.

What is a sporophyte Class 11?

(II) Sporophyte: The sporophyte is the diploid multicellular stage of the life cycle of plants. – Sporophyte develops from the zygote produced by the fusion of haploid male gamete and haploid female gamete. – It is the non-sexual phase of the plant life cycle.

What is another name for sporophyte?

sporogonium
In contrast to the sexual generation this stage is called the spore-bearing generation (sporogonium, sporophyte).

What does sporophyte consist of?

A sporophyte (/spɔːroʊˌfaɪt/) 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 difference between sporophyte and gametophyte phase?

Gametophytes are haploid (n) and have a single set of chromosomes, whereas Sporophytes are diploid (2n), i.e., they have two sets of chromosomes. A sporophyte reproduces asexually and a gametophyte sexually. Significance: For a diploid (2n) sporophyte to produce haploid (n) spores, the cells have to undergo meiosis.

Is a tree a sporophyte?

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.

What is the definition of sporophyte stage?

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.

Is sporophyte dominant is mosses?

In mosses, the gametophyte is the dominant generation, while the sporophytes consist of sporangium-bearing stalks growing from the tips of the gametophytes A sporophyte ( / spɔːroʊˌfaɪt /) is the diploid multicellular stage in the life cycle of a plant or alga.

What are some examples of a sporophyte dominant plant?

The definition of a sporophyte is a mature phase in the life cycle of plants and some algae that produce spores. An example of sporophyte is a mature fern plant . The diploid spore-producing phase in the life cycle of a plant that exhibits alternation of generations. It is the dominant stage in vascular plants.

What is part of a bryophyte sporophyte?

The sporophyte of bryophytes is called sporogonium which generally consists of a sin­gle, terminal sporangium (monosporangiate) with a bulbous foot and with or without an unbranched stalk or seta . The sporogonium is very delicate, short-lived and nutritionally dependent on its gametophyte.

Is the sporophyte dominant?

During the course of evolution, the sporophyte stage has become progressively increased. Thus, in the higher (i.e., vascular) plants the sporophyte is the dominant phase in the life cycle, whereas in the more primitive nonvascular plants ( bryophytes ) the gametophyte remains dominant.
