A typical anther of an angiosperm is

Options

A. haploid, bisporangiate
B. diploid, tetrasporangiate
C. diploid bisporangiate
D. haploid, tetrasporangiate

Answer

To answer the question "A typical anther of an angiosperm is," we need to analyze the characteristics of the anther in flowering plants (angiosperms). Here’s a step-by-step breakdown of the solution:

### Step 1: Understand what an angiosperm is
- Angiosperms are flowering plants that produce flowers and seeds. They are a major group of plants characterized by their reproductive structures.

**Hint:** Remember that angiosperms are defined by their ability to produce flowers and seeds.

### Step 2: Identify the structure of the anther
- The anther is part of the male reproductive system in plants, which includes the anther and the filament, collectively known as the stamen or androsium.

**Hint:** The anther is specifically involved in the production of pollen.

### Step 3: Describe the morphology of the anther
- A typical anther is bilobed, meaning it has two lobes. When viewed in cross-section, it reveals four compartments.

**Hint:** Visualize the anther as having two main parts that are further divided.

### Step 4: Understand the compartments of the anther
- Each of the four compartments contains microsporangia, which are the structures where pollen grains develop.

**Hint:** Microsporangia are essential for pollen production.

### Step 5: Determine the ploidy level of the cells
- The cells within the microsporangia are diploid (2n), which means they contain two sets of chromosomes.

**Hint:** Ploidy refers to the number of sets of chromosomes in a cell.

### Step 6: Identify the type of sporangiate
- Since there are four compartments in the anther, it is classified as tetrasporangiate (tetra meaning four).

**Hint:** The term "tetrasporangiate" indicates the presence of four sporangia.

### Conclusion
- Based on the analysis, a typical anther of an angiosperm is **diploid and tetrasporangiate**.

**Final Answer:** The correct option is **diploid and tetrasporangiate**.
