To solve the problem, we need to identify what flowers are called when they have both male and female reproductive organs.
1. Understanding Flower Structure:
- Stamens are the male reproductive parts of a flower (anther + filament).
- Carpels (or pistils) are the female reproductive parts (stigma + style + ovary).
2. Definition of a Bisexual Flower:
When a flower contains both stamens and carpels, it is called a bisexual flower. It has the ability to perform both male and female reproductive functions.
3. Eliminate Other Options:
- Asexual: Refers to reproduction without gametes; not related to flower anatomy.
- Conjugation: A form of genetic exchange seen in some microorganisms, not plants.
- Unisexual: Flowers having either stamens or carpels, not both.
Final Answer:
Flowers having both the stamens and carpels are called Bisexual.
