What is Sporophytic and Gametophytic?
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 Sporophytic plant body?
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 makes a plant non-vascular?
Non-vascular plants, or bryophytes, include the most primitive forms of land vegetation. These plants lack the vascular tissue system needed for transporting water and nutrients. Unlike angiosperms, non-vascular plants do not produce flowers, fruit, or seeds. They also lack true leaves, roots, and stems.
What is the life cycle of a fern?
The life cycle of the fern has two different stages; sporophyte, which releases spores, and gametophyte, which releases gametes. Gametophyte plants are haploid, sporophyte plants diploid. This type of life cycle is called alternation of generations.
What is Gametophytic generation?
In plants, the gametophyte generation is one that which begins with a spore that is haploid (n). The spore undergoes series of mitotic divisions to give rise to a gametophyte. A gametophyte is a haploid multicellular plant form. Similar to plants’ gametophyte generation, the algal gametophyte is the sexual phase.
What is Gametophytic phase?
In the gametophyte phase, which is haploid (having a single set of chromosomes), male and female organs (gametangia) develop and produce eggs and sperm (gametes) through simple mitosis for sexual reproduction. Over the course of evolution, the gametophyte stage has become progressively reduced.
Is Fern vascular plant?
fern, (class Polypodiopsida), class of nonflowering vascular plants that possess true roots, stems, and complex leaves and that reproduce by spores. The ferns constitute an ancient division of vascular plants, some of them as old as the Carboniferous Period (beginning about 358.9 million years ago) and perhaps older.
Which body part of plant is haploid?
The correct answer is Option 1, i.e Gamete. Gametogenesis refers to the process of formation of the two types of gametes – male and female. Gametes in plants are haploid cells. Ovary is the female part of the plant having ovules.
