Answer

To answer the question "Select an incorrect statement for angiosperms," we will analyze each option provided:

1. **Pollen grains and ovules are developed in specialized structures called flowers.**
- This statement is **correct**. In angiosperms (flowering plants), pollen grains (male gametes) are produced in the anthers of the stamen, while ovules (female gametes) are produced in the ovary of the pistil (carpel). Both structures are indeed found within flowers.

2. **The seeds are enclosed by fruits.**
- This statement is also **correct**. One of the defining features of angiosperms is that their seeds are enclosed within fruits, which develop from the ovary after fertilization.

3. **Dicotyledons are characterized by having two cotyledons in their leaves.**
- This statement is **incorrect**. Dicotyledons (or dicots) are characterized by having two cotyledons in their seeds, not in their leaves. Cotyledons are the first leaves that appear during seed germination.

4. **Female sex organs in a flower is the pistil or the carpel.**
- This statement is **correct**. The pistil, also known as the carpel, is indeed the female reproductive part of the flower, consisting of the stigma, style, and ovary.

From the analysis above, the incorrect statement regarding angiosperms is:

**Answer: Dicotyledons are characterized by having two cotyledons in their leaves.**
