What is androecium and gynoecium?

Androecium refers to the male fertilizing organ of a flower, typically consisting of a pollen-containing anther and a filament while gynoecium refers to the female organs of a flower, comprising the stigma, style, and ovary.

What is Corolla and calyx?

The main difference between calyx and corolla is that calyx is the whorl of sepals of a flower whereas corolla is the whorl of petals.

What is pistil also known as?

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. Also Refer: Morphology of flowering plants.

What is the function of androecium and gynoecium?

Androecium is the male reproductive part of the flower. It contains anther and filament and produces pollen grains or male gametes. Gynoecium is the female reproductive part of the flower. It contains stigma, style and ovary and produces female gamete ovule, synergids, antipodals and two polar nuclei.

What is unit of gynoecium called?

Carpels are the basic units of the gynoecium and may be free (distinct) or fused (connate). The term pistil is used in a similar manner to carpel – in some situations the terms are equivalent in meaning but not in others. For example, a flower represented by G 1 has a single carpel or a single pistil.

What is the function of calyx?

The calyx is the outermost whorl of a flower which is composed of sepals. Generally, these sepals are green, leaf-like, and protect the inner whorls of the flower in bud condition. They are also involved in producing food by photosynthesis.

What is the difference between calyx and sepals?

Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom. Collectively the sepals are called the calyx (plural calyces), the outermost whorl of parts that form a flower.

Is pistil male or female?

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.

Is pistil and carpel same?

What is the difference between a carpel and a pistil? Carpels are the basic units of the gynoecium and may be free (distinct) or fused (connate). The term pistil is used in a similar manner to carpel – in some situations the terms are equivalent in meaning but not in others.

What is main function of androecium?

(iii) Role of androecium: Production and storage of pollen grains are the main two functions of androecium. It is the male reproductive organ of a flower. (iv) Role of gynoecium: Gynoecium is the female reproductive organ of a plant. It holds ovary, which is transformed into fruit after fertilization.

What is the role of androecium?

(iii) Androecium: The point of stamen, which connects the anther and the filament is called connective. Its main function is the production of microspores, i.e., pollen grains containing male gametes within the anther lobe.

What’s the difference between a androecium and a gynoecium?

The main difference between androecium and gynoecium is that the androecium (or stamen) refers to the male part of the flower whereas the gynoecium (or pistil or carpel) refers to the female part. Androecium and gynoecium are the two, opposite reproductive organs of the flower, the sexual reproductive structures in angiosperms.

What are the major parts of the gynoecium?

Gynoecium is the female reproductive unit of the flower that produces ovules, and it is the place where fertilization takes place. Anther and filament are the major parts of the androecium. Stigma, style and ovary are the major parts of the gynoecium. Androecium involves in the production and release of pollen grains.

Where are the androeciums located on a flower?

The androecium is located centrally to the flower. Normally there are about 5-6 stamens located per flower. The main function of the androecium is to produce pollen grains. They are released from the anther into the external environment only after they mature.

Is the pistil a synonym for the androecium?

Stamen is a synonym to androecium. The pistil is a synonym to gynoecium. The androecium is considered as the male reproductive unit of the flower. It is also referred to as the stamen that is composed of anther and filament. The main function of the androecium is to produce pollen grains. The gynoecium is the female reproductive unit of the flower.
