Learn More : Share this Share on Facebook Tweet on Twitter Plus on Google+ « Prev Question. In botany, the stamen is often composed of the anther and a filament and the male organ of the flower. Meiosis of the diploid microspore mother cells in the anther produces four haploid microspores.Each of these develops into a pollen grain consisting of . The anther contains numerous sporangia, which give rise to microspores. The female sex organ consists of the stigma, which is elevated on the style and terminates at the ovary, where the female egg cells are contained within ovules. Anther: It is generally a bilobed structure that carry pollen grains in the pollen sacs. 6 years ago. the former consists of stamen morphogenesis (stages 5–9of flower development), whereas the latter includes pollen matura-tion, anther dehiscence and stamen filament elongation (stages 10–13). Moreover, the stamen produces the pollen grain while carpel produces the ovule, which involves in fertilization to produce the seed. Anthers are held up by a thread-like part called a filament. The layout diagram contains pistil, stamen and petal. d. More Answers. Biology 2nd. The stamen is homologous to the microsporophyll. Style, stigma and ovary are part of pistil. Each Stamen consist of 3 parts, a. Filament b. Anther c. Connective. Stamen definition is - a microsporophyll of a seed plant; specifically : the pollen-producing male organ of a flower that consists of an anther and a filament. The typical angiosperm anther is made up of four pollen sacs (microsporangia), grouped into two pairs. Stamens usually consist of a long slender stalk, the filament, with the anthers at the tip. Stamens consist of anthers and filaments which enclose male gametes. Pistil is the name of the female floral organ. View all notifications . Lv 7. 0. The Stamen: Male Reproductive Structure Consists of two parts: Anther and Filament The filament is a stalk that supports the anther The anther is where meiosis occurs to produce pollen Each pollen grain contains sperm cells. A typical stamen consists of an anther filament, which contains a vascular bundle, and an anther, the symmetrical halves of which are joined by a strand attached to the anther filament. Concept: Sexual Reproduction in Plants -review of Parts of a Typical Flower. 0. The pistil consists of a long cylindrical central part, called a style, that connects the lower ovary to the upper stigma, which receives and holds pollen.There may be a single pistil, as in the lily, or several to many pistils, as in the buttercup. A male reproductive part of a flower typically consists of two elements: Filament: A filament appears as a long, slender and stalk-like structure found in the stamen. Share. When the filament is not developed, the anther is said to be sessile. Plant Diversity. The anther consists of four saclike structures (microsporangia) that produce pollen for pollination. Key Areas Covered. Some stamens are similar to leaves, with the anthers at or near the margins. The stamens that get attach to tepals are epiphyllous stamens. The stamens are collectively referred to as the androecium. Pistil on the other hand is a female reproductive structure consisting of stigma, ovary and style. Formerly Peter S .

The filaments typically serve two roles; they contain the vasculature from the main plant body that terminates within the anther, and filaments elongate (often dramatically) prior to pollen dispersal. stamen Pollen-producing male organ of a flower.It consists of an anther, in which pollen is produced, on the end of a stalk-like filament.The arrangement and number of stamens is important in the classification of flowering plants. The number and length of stamens vary in different species. the filament and anther. Stamens are the male reproductive organs of flowering plants. In this, the stamen gets attached to the part of the flower of some other plant as an adhesion of stamen. A typical flower consists of four types of floral leaves called sepals, petals, stamens and carpels in distinct whorls normally known as calyx, corolla, androecium and gynoecium respectively. Chapter 32. The proximal end of the filament is attached to the thalamus or petal of the flower. Arranged around the stigma are the male sex organs or stamens. Can you explain this answer?

They are the female reproductive part of a plant producing female sex cells or ovules. The anther produces pollen (male reproductive cells). Each stamen consists of the filament, the name given to the long stamen stalk, and the anther, a sack on the tip of the filament that is full of pollen grains. 1 Answer. c) Stamens: Consists of an anther and a filament. 0. ...

Stamen: The stamen is the Latin term for the warp thread in an upright loom. The stamen is homologous to the microsporophyll. STAMEN is consists of the filament and anther. Each stamen consists of three parts, filament, anther and a connective. Filament: Filament is the stalk in which the anther is borne. Microspores are formed from the cells of the archesporium after meiosis. They consist of an anther, the site of pollen development, and in most species a stalk-like filament, which transmits water and nutrients to the anther and positions it to aid pollen dispersal. A filament of a stamen emerges out from the thalamus or peduncle and gives rise to a knob-like anther. stigma, style, ovary) Stamen: The term for the collective male floral parts (i.e. Place the following in order of decreasing radius. Stamen is consists of the filament and anther anther. The number of stamens is a factor in classifying plant families, e.g., there are 5 (or multiples of 5) in the rose family and 10 in the pulse family. a single sepal, four or more petals, and the entire carpel.
