What do you understand by sporophyte and a gametophyte explain using suitable example?

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. Plants produce gametes with the help of their sex organs. The generation of plants that produce spores is called sporophyte.

What separates the sporophyte and gametophyte generations in Bryophytes?

The spores develop into tiny, separate gametophytes, from which the next generation of sporophyte plants grows. In seed plants, the gametophyte generation takes place in a cone or flower, which forms on the mature sporophyte plant.

What is the difference between sporophyte of gymnosperms and Sporophytes of Bryophytes?

Gymnosperms are seed-bearing plants and include cycads and conifers. Gametophyte is the dominant generation of Bryophytes. Sporophyte is the dominant generation of Pteridophytes. Sporophyte is the dominant generation of Gymnosperms.

What is sporophyte in bryophyte?

The sporophyte of a bryophyte is a simple unbranched structure that consists of a spore forming organ called sporangium. Complete Answer: Sporophytes produce spores and they are not photosynthetic in nature. For nutrition, they are dependent on the gametophyte (implies that they are parasitic on gametophyte).

How do sporophyte and gametophyte stages differ?

The plant’s haploid phase is called gametophyte and the diploid phase is called the sporophyte….

Difference Between Gametophyte and Sporophyte
Sporophytes	Gametophytes
Sporophytes have two sets of chromosomes	Gametophytes have a single set of chromosomes
Sporophytes reproduce asexually	Gametophytes produce sexaully

What is a gametophyte and sporophyte?

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 relationship between the sporophyte and gametophyte generations?

How do sporophyte and gametophyte differ?

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.

How are Gametophytes of bryophyte and Gymnosperm different?

“The gametophytes of bryophytes and pteridophytes are different from that of gymnosperms. Male and female gametophyte have free existence in bryophytes and pteridophytes but not in Gymnosperms. They remain within sporangia retained on sporophytes.

Is sporophyte dependent on gametophyte in bryophytes?

The bryophytes show an alternation of generations between the independent gametophyte generation, which produces the sex organs and sperm and eggs, and the dependent sporophyte generation, which produces the spores. In most vascular plants, however, the gametophyte is dependent on the sporophyte.

What is the difference between gametophyte and sporophyte?

Gametophyte is predominant; sporophyte is completely dependent on gametophyte. 1. Sporophytic Plant Body: Polysporangiate, differentiated into root, stem and leaves; true roots are absent in some species (e.g., Psilotum) 2. Vascular System: In pteridophytes, vascular system is present; however, the xylem is without vessels (except,.

Where in the sporophyte life stage the plant is 2n?

Where in the sporophyte life stage the plant is 2n, meiosis occurs, then the plant is in the gametophyte life stage (1n), where gametophyte spores undergo mitosis and two gametes (an egg and a sperm) are produced. The gametes undergo fertilization and then a zygote is formed (2n). Then the cycle starts over.

Why do bryophytes lack roots leaves and stems?

Bryophytes lack roots, leaves, and stems because they are non-vascular plants and do not have xylem or phloem to transport water and sucrose. The plant goes in between two life stages: gametophyte and sporophyte.

What type of spores are produced by gymnosperms?

• Sporophyte produces two types of spores (heterosporous) •Megasporangium–undergoes meiosis to produce megaspores (female gametophyte) •________sporangium–undergoes meiosis to produce haploid microspores, germinate to produce male gametophyte (pollen) • Many gymnosperms use wind for pollination and seed dispersal Wood produced by gymnosperms
