sporophyte In plants, fungi, and certain algae, the individual organism or generation of organisms that produces spores. A sporophyte is formed from the union of the nuclei of male and female reproductive cells, and each of its cells has two sets of chromosomes.

Gametophyte 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.

- A: According to the Encyclopaedia Britannica, gametophytes are the haploid phase and sporophytes are the diploid phase of plants and algae that undergo the alternation of generations.

Chlorophyta Chlorophyta is a division of green algae, informally called chlorophytes. The name is used in two very different senses, so care is needed to determine the use by a particular author.

Saprophyte noun, plural: saprophytes. (botany) An organism (especially a plant or plant-like) that feeds, absorbs or grows on decaying organic matter. Supplement. The term saprophyte is no longer in popular use since there are no true embryophytes or true plants that are saprophytic in nature. Plants that are once thought of as saprophytes such as orchids and monotropes are now considered as parasites on fungi.

- Organization of the Plant Body Coordination of primary and secondary meristematicgrowth produces the body of the adult sporophyte plant.Plant bodies do not have a fixed size. Parts such as leaves,roots, branches, and flowers all vary in size and numberfrom plant to plant—even within a species.

- Pteridophytes or Pteridophyta, in the broad interpretation of the term (or sensu lato), are vascular plants (plants with xylem and phloem) that reproduce and disperse via spores.Because they produce neither flowers nor seeds, they are referred to as cryptogams.he group includes ferns, horsetails, clubmosses, spikemosses and quillworts. These do not form a monophyletic group, because ferns and horsetails are more closely related to seed plants than to lycophytes (clubmosses, spikemosses and quillworts).

Kingdom Plantae : Plant Kingdom The life cycle of bryophytes consists of an alternation of two stages, or generations, called the sporophyte and the gametophyte. Each generation has a different physical form.

Difference Between Sporophyte and Gametophyte Sporophyte vs Gametophyte. The reproduction of plants can be categorized into two different phases, asexual reproduction and sexual reproduction. During the evolution of plant life, development of the reproduction system of a plant was varied depending on the complexity of the plant category.

Sporophyte In flowering plants, the sporophyte comprises the whole multicellular body except the pollen and embryo sac. Bryophytes (mosses, liverworts and hornworts) have a dominant gametophyte phase on which the adult sporophyte is dependent for nutrition.The embryo sporophyte develops by cell division of the zygote within the female sex organ or archegonium, and in its early development is therefore nurtured by the gametophyte.n flowering plants the gametophytes are very reduced in size, and are represented by the pollen and the embryo sac. The sporophyte produces spores (hence the name) by meiosis, a process also known as reduction division that reduces the number of chromosomes in each spore mother cell by half.

spore A usually one-celled reproductive body that can grow into a new organism without uniting with another cell. Spores are haploid (having only a single set of chromosomes). Fungi, algae, seedless plants, and certain protozoans reproduce asexually by spores. Plant spores that are dispersed by the wind have walls containing sporopollenin. See more at alternation of generations.

Sporophyte: Definition & Examples In nonvascular plants, like mosses, the sporophyte generation is not the dominant generation. This means that the sporophyte is smaller is size and shorter lived than the gametophyte generation. When you think of a moss, you probably picture a tiny green leafy plant, like the one shown below. sporophyte is created by sexual reproduction of the gametophyte generation. Gametophytes make haploid unicellular gametes, or sperm and eggs. When a sperm cell fuses with an egg cell this is called fertilization. It creates a unicellular diploid zygote.

Dictionary Definition The sporophyte stage of a plant undergoes meiosis which produces  haploid spores. Spores can also be produced during meiosis in the  plant life cycle. spore is a reproductive structure that is adapted for dispersal and surviving for extended periods of time in unfavorable conditions. Spores form part of the life cycles of … many bacteria, plants, algae, fungi and some protozoans.

Alternation of generations A multicellular gametophyte, which is haploid with n chromosomes, alternates with a multicellular sporophyte, which is diploid with 2 n chromosomes, made up of n pairs. A mature sporophyte produces spores by meiosis, a process which reduces the number of chromosomes to half, from 2 n to n.

Sporophyte: Definition & Examples Let's take a closer look at the sporophyte generation. Function of a Sporophyte. The job of a sporophyte is to produce spores. This makes sense because 'spore' is part of the word 'sporophyte.' The 'phyte' part just means plant. So, a sporophyte is a plant that has spores. Spores are haploid reproductive cells.

- Using the process of meiosis, sporophytes produce spores. These spores then develop into gametophytes. Conversely, gametophytes produce gametes. In many plants both male and female gametes are produced. These gametes develop into sporophytes, which starts the cycle of alteration of generations over again.

Sporophyte: Definition & Examples Gametophytes make haploid unicellular gametes, or sperm and eggs. When a sperm cell fuses with an egg cell, this is called fertilization. It creates a unicellular diploid zygote. This zygote undergoes many rounds of mitosis to become multicellular. We now have a multicellular diploid organism, or sporophyte. Sporophytes in Plants

Chapter 29 Homework The gametophyte is the dominant stage of the life cycle in mosses; the sporophyte develops on the body of a gametophyte, where it lives for a briefer time than the gametophyte's life span. In ferns, the sporophyte is dominant; the gametophyte is tiny and short-lived. Both mosses and ferns have swimming sperm that require moisture to reach an egg.

- A multicellular gametophyte, which is haploid with n chromosomes, alternates with a multicellular sporophyte, which is diploid with 2n chromosomes, made up of n pairs. A mature sporophyte produces spores by meiosis, a process which reduces the number of chromosomes to half, from 2n to n. Because meiosis is a key step in the alternation of generations, it is likely that meiosis has a fundamental adaptive function.
