What is stamen and pistil?
Stamen: The pollen producing part of a flower, usually with a slender filament supporting the anther. Anther: The part of the stamen where pollen is produced. Pistil: The ovule producing part of a flower. The ovary often supports a long style, topped by a stigma.
Stamen is the male reproductive part of a flower, while pistil is the female reproductive part of a flower.
Staminate (male) flowers contain stamens, but no pistils. Plants with imperfect flowers are further classified as monoecious or dioecious.
Pistils: Female Reproductive Organs
The pistil includes an ovary (where the ovules are produced; ovules are the female reproductive cells, the eggs), and a stigma (which receives the pollen during fertilization).
Stamen refers to a flower's centrally-located, pollen-producing male organ. The male parts, called stamens, look like long stalks (known as filaments) with a little round shape at their end (called the anther), which contains the plant pollen.
The pistil is the innermost, seed-bearing, female part of a flower. It is located generally to the centre and consists of a swollen base called the ovary. The pistil can also be referred to as a collection of carpels, which are fused together.

stamen, the male reproductive part of a flower. In all but a few extant angiosperms, the stamen consists of a long slender stalk, the filament, with a two-lobed anther at the tip. The anther consists of four saclike structures (microsporangia) that produce pollen for pollination.
Stamens and pistils are not present together in all flowers. When both are present the flower is said to be perfect, or bisexual, regardless of a lack of any other part that renders it incomplete (see photograph). A flower that lacks stamens is pistillate,…
The male parts are called stamens and usually surround the pistil. The stamen is made up of two parts: the anther and filament. The anther produces pollen (male reproductive cells). The filament holds the anther up.
What is a female part of flower?
Pistil: The pistil is known as the female flower part. It has an ovary, the style, and stigma which contains pollen. These all contribute to the formation of gynoecium or the female reproductive part.
Answer and Explanation: No, the stamen does not create sperm, but it does create the grains of pollen that contain a microgametophyte that then is able to create sperm cells.
The ovaries contain the female gamete cell, called the oocyte. In non medical terms, the oocyte is called the “egg”. The ovaries are filled with follicles. Follicles are fluid-filled structures in which the oocyte (also called egg) grows to maturity.
In animals, female gametes are called ova or egg cells, and male gametes are called sperm. Ova and sperm are haploid cells, with each cell carrying only one copy of each chromosome. During fertilization, a sperm and ovum unite to form a new diploid organism.
The testicl*s (testes).
Each is an egg-shaped structure located in the scrotum. The testes produce sperm and also produce male hormones.
Stamens are the male reproductive organs of flowering plants. 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.
The two major types of stamen cycly are uniseriate, having a single whorl of stamens, and biseriate, with two whorls of stamens.
It is the female reproductive part of the plant. It consists of two parts: anther and filament. It consists of three parts: stigma, style and ovary. It produces pollen grains.
carpel, One of the leaflike, seed-bearing structures that constitute the innermost whorl of a flower. One or more carpels make up the pistil. Fertilization of an egg within a carpel by a pollen grain from another flower results in seed development within the carpel. Related Topics: ovule placenta ovary stigma style.
The names pistil and carpel are often used interchangeably, but they actually refer to different parts of a flower. A carpel is a part of the pistil that comprises the style, stigma, and ovary. In the pistil, the carpel is the ovule bearing leaf-like part extending out to the style.
What is placenta in flower?
placenta, plural Placentas, orPlacentae, in botany, the surface of the carpel (highly modified leaf) to which the ovules (potential seeds) are attached. The placenta is usually located in a region corresponding somewhat to the margins of a leaf but is actually submarginal in position.
Bisexual flowers contain both stamen (male reproductive part) and pistil (female reproductive part) in the same flower. E.g., rose, hibiscus, mustard, etc. On the other hand, unisexual flowers contain either stamen or pistil.
A flower that has both stamens and pistil (androecium and gynoecium) is known as a bisexual flower. Eg:- Datura, hibiscus, Ipomea, is called bisexual.
The anthers are the orange/yellow structures often seen in the centre of a flower. Pollen from the anthers of one flower is transferred to the stigma of another usually either by wind, or by animals, especially insects.
Anther, an′thėr, n.
Stamen is the male reproductive part of the flower that typically consists of a pollen-containing anther and a filament. The carpel is the female reproductive organ of a flower that consists of an ovary, a stigma, and a style and may be single or may be present in a group in some plants.
Complete Answer: - The male organ of a flower is called stamen which makes the male gametes or the male sex cells of the plant. These male gametes are present inside the pollen grains.
Final answer: A unisexual flower that has only stamen is called a staminate flower.
The two primary parts of the Rose plant are the stamen and the pistil which are the male and female components respectively. Other parts include petals, leaves, and sepals.
The flower that has only male or female reproductive parts i.e., either stamens or carpels are present are unisexual flowers. Examples of unisexual flowers are Bitter gourd, papaya, pumpkin, and cucumber.
What makes a plant male or female?
The “male” portion of the flower is the pollen-loaded stamen, while the egg-holding pistil is the “female” part. Most plants sprout bisexual flowers (which have both male and female parts), but plants like squash grow separate male and female flowers — still others have both bisexual and single-sex flowers.
The male part of flowering plants is the stamen. This consists of an anther supported by a single stalk, the filament. The anther usually contains four pollen sacs which are responsible for producing pollen grains. Each pollen grain is a single cell containing two male gametes.
The female organs,comprised of stigma, style, and ovary, collectively are called the pistil. The male organs consist of the anther and filament and are collectively called the stamen.
Stamen is the male part of the flower. It consists of the anther and filament.
The pistil is a plant's female part. It generally is shaped like a bowling pin and is located in the flower's center. It consists of a stigma, style and ovary. The stigma is located at the top and is connected by the style to the ovary.
Androecium is the male reproductive part of a flower. It consists of stamens. Stamens produce pollen in terminal sac like structures called anthers. Stamens usually consist of a long slender stalk, filament with the anthers at the tip.
Thus, in angiosperms (flowering plants) and gymnosperms (plants with “naked seeds”), the male structures produce pollen (which contain sperm), and the female structures have one or more ovaries (which contain eggs known as ovules).
A woman is born with all her eggs. Once she starts her periods, 1 egg develops and is released during each menstrual cycle.
Well, sperm cells are actually really tiny. In fact, they are some of the smallest cells in the human body, and measure just 0.005cm.
Abnormal Ovarian Development
Some women are born with ovaries that can not produce eggs. Women with this condition do not go through puberty and usually never have a period.
Can a woman produce sperm?
However, some people who identify as women may produce sperm. If two women want to make a baby and one is cisgender and one is transgender (meaning they were assigned male at birth), there are several ways their sperm and eggs might meet, including through penetrative intercourse or ART.
The zygote is endowed with genes from two parents, and thus it is diploid (carrying two sets of chromosomes). The joining of haploid gametes to produce a diploid zygote is a common feature in the sexual reproduction of all organisms except bacteria.
In humans and most other anisogamous organisms, a zygote is formed when an egg cell and sperm cell come together to create a new unique organism. In single-celled organisms, the zygote can divide asexually by mitosis to produce identical offspring.
testicl*s (testes)
The testes are responsible for making testosterone, the primary male sex hormone, and for producing sperm. Within the testes are coiled masses of tubes called seminiferous tubules.
That means a fertile man may produce between 40 million and 1800 million sperm cells in total, though the majority produce between 40 and 60 million sperm cells per millilitre, giving an average total of 80 to 300 million sperm per ejacul*tion.
sta·men ˈstā-mən. plural stamens also stamina ˈstā-mə-nə ˈsta- : a microsporophyll of a seed plant. specifically : the pollen-producing male organ of a flower that consists of an anther and a filament see flower illustration.
Stamens are the male reproductive organs of flowering plants. 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.
Stamen is the male reproductive part of a flowering plant. The stamens are arranged in a whorl, collectively known as the androecium. They are found in the centre of the flower along with the stigma, if present. They can be either one in number or as many as thousands in number.
Stamens and pistils are not present together in all flowers. When both are present the flower is said to be perfect, or bisexual, regardless of a lack of any other part that renders it incomplete (see photograph). A flower that lacks stamens is pistillate,…
The number of stamens in a flower is majorly a multiple of the number of perianth members present in a single whorl. For example, let us consider a flower has 5 sepals and 5 petals, then it might have either 5 stamens or 10 stamens.
Where is stamen on a flower?
In self-pollinating flowers, stamen usually surround the female organ of the plant, which is located in the absolute center of the flower (called the pistil). The close proximity of the flower's female and male reproductive organs make it easier for reproduction to occur.
The female part is the pistil. The pistil usually is located in the center of the flower and is made up of three parts: the stigma, style, and ovary. The stigma is the sticky knob at the top of the pistil. It is attached to the long, tubelike structure called the style.
The number of stamens in a flower is typically a multiple of the number of perianth members in a single whorl. For example, if a flower has 5 sepals and 5 petals, it might have either 5 stamens or 10 stamens.
