The correct Answer is:
To answer the question regarding a typical anther of an angiosperm, we will break down the characteristics and classifications of anthers step by step. ### Step-by-Step Solution: 1. **Definition of Anther**: - The anther is a part of the stamen, which is the male reproductive organ of flowering plants (angiosperms). It is responsible for producing pollen grains. 2. **Structure of Anther**: - A typical anther is composed of two main parts: - **Filament**: The stalk that supports the anther. - **Theca**: The anther itself, which is typically bilobed. 3. **Locules and Microsporangia**: - The anther contains four locules (chambers), and each locule has microsporangia. These microsporangia are where pollen grains develop. 4. **Types of Anthers**: - Anthers can be classified based on their structure: - **Monothecus**: Anther with one lobe (not typical for angiosperms). - **Dithecus**: Anther with two lobes (typical for angiosperms). - **Bisporangiate**: Anther with two microsporangia (not typical for angiosperms). - **Tetrasporangiate**: Anther with four microsporangia (typical for angiosperms). 5. **Conclusion**: - A typical anther of an angiosperm is **dithecus tetrasporangiate**. This means it has two lobes (dithecus) and contains four microsporangia (tetrasporangiate). ### Final Answer: The correct classification of a typical anther of an angiosperm is **Dithecus Tetrasporangiate**. ---
