Megasporophyll of Cycas is homologous to

Options

A. Option1 stamen
B. Option2 petal
C. Option3 sepal
D. Option4 carpel

Explanation

To solve the question "Megasporophyll of Cycas is homologous to", we will follow these steps:

### Step 1: Understand the Structure of Cycas
Cycas is a dioecious plant that belongs to the group of Gymnosperms. It has two types of sporophylls: microsporophylls and megasporophylls.

**Hint:** Identify the types of sporophylls in Cycas and their functions.

### Step 2: Define Megasporophyll
The megasporophyll is the structure in Cycas that bears the megasporangia, which are the ovules. These ovules develop into female gametophytes, specifically the endosperm.

**Hint:** Remember that megasporophylls are related to female reproductive structures.

### Step 3: Compare with Angiosperms
In angiosperms, the equivalent structure to the megasporophyll is the carpel. The carpel also contains ovules and is involved in the female reproductive process.

**Hint:** Consider the relationship between gymnosperms and angiosperms when comparing structures.

### Step 4: Identify the Homologous Structure
Since the megasporophyll of Cycas is responsible for bearing ovules, and in angiosperms, the carpel serves a similar function, we can conclude that the megasporophyll of Cycas is homologous to the carpel in angiosperms.

**Hint:** Look for structures that serve similar functions in different plant groups.

### Conclusion
Thus, the answer to the question is that the megasporophyll of Cycas is homologous to the carpel.

**Final Answer:** The megasporophyll of Cycas is homologous to the carpel.
