What is a sporophyte and gametophyte in flowering plants?

The multicellular diploid plant structure is called the sporophyte, which produces spores through meiotic (asexual) division. The multicellular haploid plant structure is called the gametophyte, which is formed from the spore and give rise to the haploid gametes.

What is the sporophyte in flowering plants?

A sporophyte (/ˈspɔːr. əˌfaɪt/) is the diploid multicellular stage in the life cycle of a plant or alga. … In flowering plants the gametophytes are very reduced in size, and are represented by the germinated pollen and the embryo sac.

Are flowering plants sporophyte or gametophyte?

In flowering plants, the gametophyte generation takes place in a flower, which forms on the mature sporophyte plant. Each male gametophyte is just a few cells inside a grain of pollen. Each female gametophyte produces an egg inside an ovule.

What is the gametophyte of a flowering plant?

In flowering plants, the pollen grain is the male gametophyte and the embryo sac is the female gametoph yte. The male gametophyte completes its early development within the anther.

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 the function of sporophyte and gametophyte?

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 a sporophyte plant?

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 gametophyte?

The multicellular diploid plant structure is called the sporophyte, which produces spores through meiotic (asexual) division. The multicellular haploid plant structure is called the gametophyte, which is formed from the spore and give rise to the haploid gametes.

Where is the gametophyte in flowering plants?

The Gametophytes

The male gametophyte develops inside the pollen grain. The female gametophyte develops inside the ovule. In flowering plants, gametophyte phases are reduced to a few cells dependant for their nutrition on the sporophyte phase.

Are plants gametophytes?

Unlike animals(see Chapter 2), plants have multicellular haploid and multicellular diploid stages in their life cycle. Gametes develop in the multicellular haploid gametophyte (from the Greek phyton, “plant”).

What gametophyte means?

gametophyte, in plants and certain algae, the sexual 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 nonsexual phase is the sporophyte.

Where does the sporophyte grow and receive nutrients?

A dependent sporophyte is a sporophyte that is small and grows attached to the gametophyte. It obtains nutrients from the gametophyte.

What is a gametophyte structure?

A gametophyte represents the sexual phase of the plant life. … It is in the haploid gametophyte structure that gametes are formed. These male and female sex cells, also known as eggs and sperm, unite during fertilization to form a diploid zygote.

What is the function of a 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 role of the sporophyte?

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. … This diagram shows the alternation of generations between the diploid sporophyte and the haploid gametophyte.

What is gametophyte and sporophyte Class 11?

– The gametophyte is the haploid sexual phase of the plant life cycle. … (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.
