What is the description of anther?

noun, plural: anthers. (1) Pollen-bearing structure in the stamen (male organ) of the flower usually located on top of the filament of the stamen. (2) Plant structure containing the pollen.

Which best describes purpose of the anther?

7) The anthers of a flower are the male reproductive organ on the top of the stamen, which produce pollen. Pollen is the male gametophyte (sex cell). Male parts that contain pollen] is the correct answer.

Why anther is called as Tetrasporangiatestructure?

The male sex organ of plants is Stamen which has two parts: the long and slender stalk called the filament and a terminal generally a bilobed structure known as the anther. Thus, the anther is tetrasporangiate because it’s four microsporangia.

Is the male part of the flower?

As a plant’s reproductive part, a flower contains a stamen (male flower part) or pistil (female flower part), or both, plus accessory parts such as sepals, petals, and nectar glands (Figure 19). The stamen is the male reproductive organ. It consists of a pollen sac (anther) and a long supporting filament.

Is anther a Tetrasporangiate?

Anthers typically consist of two compartments called thecae (singular theca), with each theca containing two microsporangia (the fusion product of which is a locule). (Thus, anthers are typically tetrasporangiate.)

Which anther is called as Tetrasporangiate structure?

Due to the presence of four pollen sacs in dithecus anther, it is called as tetrasporangiate structure.

Is anther trigonal?

The anther is four sided i.e. it has four locules consisting of four microsporangia located in each locule which develops further and become the pollen sacs. Thus, an anther is tetrasporangiate because it has four microsporangia. So, the correct answer is A.

How many types of anther are there?

Standard anther attachment types are basifixed, anther attached at its base to apex of the filament; dorsifixed, anther attached dorsally and medially to the apex of the filament; and subbasifixed, anther attached near its base to the apex of the filament.
