Identifying Unisexual Plants in Biology

A unisexual plant produces flowers having either only male (stamens) or only female (pistil) reproductive organs. In contrast, bisexual plants have flowers containing both male and female organs.

Analysis of Plant Options

• Papaya: Papaya plants are typically dioecious, meaning they have separate male and female plants. Their flowers are therefore unisexual.
• Mustard: Mustard plants possess flowers that contain both stamens and pistils, making them bisexual.
• Pea: Pea flowers have both male (stamens) and female (pistil) parts, classifying them as bisexual.
• China rose: China rose flowers are also bisexual, equipped with both stamens and a pistil.

Conclusion on Unisexual Plant

Based on the analysis, the Papaya plant is the only one among the options that typically features unisexual flowers.
