What is the difference between gamete and gametophyte

Figure 1: Formation of Gametes. Furthermore, gametes are produced inside sex organs. Male gametes are produced inside antheridia while female gametes are produced inside archegonia in plants.

On the other hand, in animals, they are produced inside testis and ovaries, respectively. However, the main function of gametes is to fuse with the opposite gamete to form the zygote.

Gametophyte is the haploid generation produced during the alteration of generations of plants and algae. It arises from a haploid spore produced by the sporophyte. Moreover, gametophyte is a multicellular structure, which contains male and female sex organs responsible for the production of gametes.

These sex organs are commonly known as gametangia and they undergo mitosis to produce haploid gametes. The zygote produced by the fertilization of gametes then gives rise to the sporophyte, which is diploid. Moreover, the gametophyte of bryophytes and algae is the dominant phase of the life cycle while in other plants, the dominant phase of the life cycle is the sporophyte. Also, some bryophytes including liverworts develop male and female gametophytes separately by the germination of microspores and megaspores respectively.

Other plants excluding seed plants produce independent gametophytes from their sporophytes. However, seed plants develop gametophytes at the microscopic level. Furthermore, some plants have monoicous gametophytes while some have dioicous gametophytes.

Monoicous gametophyte produces both sperm and eggs whereas dioicous gametophytes produce separate gametes either sperm or egg but never both. Gamete and gametophyte are two haploid structures of sexual phase of the living cycles of plants and algae. Gametophytes contain sex organs that involve the production of gametes.

On the other hand, the gametes are the sex cells or the germ cells, which undergo fertilization to form a zygote, which is diploid. Therefore, this is the key difference between gamete and gametophyte.

Furthermore, the gametes and gametophytes are of two types; male and female. While the female gametophyte produces female gamete or the egg cell, the male gametophyte produces male gamete or the sperm cell.

Moreover, another difference between gamete and gametophyte is that the gamete is a haploid unicellular structure while the gametophyte is a haploid multicellular structure.

The below infographic outlines the difference between gamete and gametophyte based on their struture, importance and role in the sexual reproduction. Life cycles of plants alternate mainly via two generations such as sexual phase and asexual phase. Here, the sexual phase is the gametophytic generation which is haploid.

Further, the gametophytes bear sex organs to produce gametes or the sex cells. While the female gametophytes produce egg cells, the male gametophytes produce sperm cells. Besides, the gametes are also haploid, and they fuse with the opposite sex gamete during the sexual reproduction to form the zygote.

This is the difference between gamete and gametophyte. Other plants excluding seed plants produce independent gametophytes from their sporophytes. During the evolution of plant life, a variation can be seen in the development of the reproductive system of a plant depen… Male gametes are produced inside antheridia while female gametes are produced inside archegonia in plants.

As a adjective haploid is cytology of a cell having a single set of unpaired chromosomes, such as a gamete. Male gametophyte of gymnosperms: Distinct male gametophyte may not be present: Distinct male gametophyte is always present. Female sex organ of the female gametophyte is archegonium. Moreover, the gametophyte of bryophytes and algae is the dominant phase of the life cycle while in other plants, the dominant phase of the life cycle is the sporophyte. Differences between male and female gametophyte is- microspore pollen grain represent male gametophyte whereas megaspore embryo sac represent female gametophyte in sexual reproducing in flowering plant.

Trending questions. Following are the differences between both stages: The gametophyte is the haploid n state in the life cycle whereas sporophyte is the diploid 2n state in the life cycle. Thus, a gamete is a reproductive cell while gametophyte is the haploid phase of the life cycle of a … Lastly, wind plays an important role in pollination in gymnosperms because pollen is blown by the wind to land on the female cones.

Examples ofgymnosperms include pine, conifers, cycads, Gnetophytes, Ginkgo, spruce, cactusand fir. A gamete is a reproductive cell produced as a result of sexual reproduction of both animals and plants. They collectively form the haploid or gametophyte phase of the life cycle. A gametophyte represents the sexual phase of the plant life.

The two forms of gametes are male and female gametes. While the female gametophyte produces female gamete or the egg cell, the male gametophyte produces male gamete or the sperm cell. Both algae and plants show these structures, which give rise to the phenomenon of alternation of … C fusion between egg and male gamete.

Spore formation takes place post meiosis whereas gamete formation either occurs directly or through mitosis. A male gametophyte is a haploid adult stage of a male organism that produces gametes.

Besides, the gametes are also haploid, and they fuse with the opposite sex gamete during the sexual reproduction to form the zygote. Spore is the first cell of the gametophyte, which germinate to produce gametophyte. Difference Between Gamete And Gametophyte. Antheridia are found in the androecium, and they produced male gametes. In plants, alternation of generations exists, where the members have haploid and diploid phases.

Degree in Plant Science, M. Difference Between Gamete and Gametophyte Definition. This conversation is already closed by Expert Was this answer helpful? Moreover, gametophyte is a multicellular structure, which contains male and female sex organs responsible for the production of gametes.

In flowering plants, the male gametophyte or pollen grain plays a vital role in plant fertility and crop production through the generation and delivery of the male gametes to the embryo sac for double fertilization.

This cycle is named alternation of generations and organisms alternate between a sexual phase, or gametophyte generation and an asexual phase, or sporophyte generation. Gametophytes are the sexual phase of the life cycle which produces gametes. Monoicous gametophyte produces both sperm and eggs whereas dioicous gametophytes produce separate gametes either sperm or egg but never both.

There are two types of gametophytes; female gametophyte and male gametophyte. Which one of the following is the major difference between mosses and ferns? Cloudflare Ray ID: 5db6bdc5eac 2. The male gamete is conical from the front while the female gamete is spherical. Female gametophyte produces egg cells or the female gametes while male gametophyte produces sperm cells or the male gametes.

Gamete and gametophyte are haploid. Male gametophyte a 3-celled structure comes out of the microspore by forming a pollen tube. The main feature of gametes is the presence of half of the chromosomes when compared to a vegetative cell of the same species. Furthermore, gametes are produced inside sex organs. The gametophyte is a haploid phase in which haploid male and female gametes are produced whereas; sporophyte is a diploid phase in which diploid spores are produced.

Gametangium is a related term of gametophyte. Here, the sexual phase is the gametophytic generation which is haploid. The predominant plant body is a sporophyte in pteridophytes, while it is a gametophyte in bryophytes. They undergo fertilization process and produce a diploid zygote that can develop into a completely new individual. However, in certain species of fungi and algae, identical male and female gametes can be seen.

Plants reproduce via asexual reproduction as well as via sexual reproduction. Each gamete carries half a genotype, since each gamete whether this is a male gamete or a female gamete is a haploid, a single set of chromosomes. Besides the above, gamete fuses with a gamete of the opposite sex to form the zygote while gametophyte is the sexual phase of the plant life cycle and it is responsible for the production of gametes. Below is a Tabular representation highlighting some of the differences between Sporophyte and Gametophyte stages of the Plant Life Cycle.

Samanthi Udayangani holds a B. Apart from its intrinsic importance in sexual reproduction, the simpl… The megaspore mother cell in the female cone divides by meiosis to produce four haploid megaspores; one of the megaspores divides to … In the life cycle of plants and certain organisms, male and female gametophytes can be seen. What are the Similarities Between Gamete and Gametophyte?

Female gamete is called ovum whereas the male gamete is called as the sperm. Furthermore, the gametes and gametophytes are of two types; male and female. Hence they contain half of the genetic material.

Hence they produce gametes via mitosis.
