The female gametophyte of Pinus differs from that of the angiosperm in having

Options

A. Oosphere
B. Archegonia
C. Developed from megaspore.
D. None of the above.

Answer

To solve the question regarding how the female gametophyte of Pinus differs from that of angiosperms, we can follow these steps:

### Step 1: Understand the Context
- Pinus is a genus of gymnosperms, which are seed-producing plants that do not form flowers or fruits.
- Angiosperms, on the other hand, are flowering plants that produce seeds enclosed within a fruit.

**Hint:** Identify the key differences between gymnosperms and angiosperms.

### Step 2: Identify the Female Gametophyte Structures
- In gymnosperms like Pinus, the female gametophyte develops within the ovule and is typically associated with structures called archegonia.
- In angiosperms, the female gametophyte is more simplified and does not have archegonia; instead, it contains the egg cell directly.

**Hint:** Look for specific structures that are present in one group but absent in the other.

### Step 3: Analyze the Options Given
- The question provides several options regarding the characteristics of the female gametophyte.
- One of the options mentions the presence of archegonia, which is a structure that is indeed found in the female gametophyte of Pinus but is absent in angiosperms.

**Hint:** Compare the structures mentioned in the options with what you know about gymnosperms and angiosperms.

### Step 4: Conclude the Correct Answer
- Since the female gametophyte of Pinus has archegonia, which is not present in angiosperms, this is the key difference.
- Therefore, the correct answer to the question is that the female gametophyte of Pinus differs from that of angiosperms in having archegonia.

**Hint:** Focus on the unique features of the female gametophyte in both groups to find the answer.

### Final Answer:
The female gametophyte of Pinus differs from that of the angiosperm in having archegonia.
