Structure of Dithecous Anther
The structure of the Dithecous anther is explained as follows:
- Bilobed Structure: The anther is typically bilobed, meaning it consists of two lobes or sacs.
- Connective Tissue: A connective tissue called the connective holds the two lobes of the anther together.
- Locules: Each lobe of the anther contains a pair of locules (pollen sacs), where pollen grains are produced and mature.
- Microsporangia: Microsporangia are the specific structures within the locules where microspore mother cells undergo meiosis to produce microspores.
- Pollen Development: Microspores mature into pollen grains within the microsporangia, undergoing a process that involves the formation of a protective coat.
- Dehiscence: Dithecous anthers typically undergo dehiscence, where the lobes split open to release mature pollen for pollination.
- Filament Attachment: The anther is attached to the filament, which is part of the stamen, the male reproductive organ of the flower.
- Pollen Release: Upon maturation, the anther releases pollen into the surrounding environment, facilitating the transfer of male gametes for fertilization.
Dithecous Anther – Structure, Formation, and Theca
The dithecous anther is a bilobed structure found in flowering plants’ stamens. The dithecous anther consists of four microsporangia, two in each lobe. Upon maturation, the anther undergoes dehiscence, releasing pollen for pollination and fertilization. Dithecous anthers examples include solanum and mustard.
The dithecous anther plays a crucial role in the sexual reproduction and genetic diversity of angiosperms. In this article, we will learn about the structure, function, and formation of the dithecous anther in detail.
