Question:

Example of bisexual flower is :

Show Hint

A {bisexual flower} has {both} male (stamens) and female (pistil/carpel) parts in the same flower.
{Hibiscus:} Clearly shows both sets of organs.
Papaya: Often has separate male and female plants (dioecious), so flowers are unisexual.
Cucumber & Maize: Have separate male and female flowers on the same plant (monoecious), so individual flowers are unisexual.
  • Papaya
  • Hibiscus
  • Cucumber
  • Maize

The Correct Option is B

Solution and Explanation

Concept: Flowers can be classified based on the presence of male and female reproductive organs.
Bisexual flower (or perfect flower): A flower that has both male reproductive organs (stamens, which produce pollen) and female reproductive organs (pistil/carpel, which contains ovules).
Unisexual flower (or imperfect flower): A flower that has either only male reproductive organs (staminate flower) or only female reproductive organs (pistillate/carpellate flower). Plants can be:
Monoecious: Have separate male and female flowers on the {same} plant (e.g., maize, cucumber).
Dioecious: Have male flowers on one plant and female flowers on a {different} plant (e.g., papaya). Step 1: Analyzing the options
(1) Papaya (Carica papaya): Papaya plants are typically dioecious, meaning individual plants bear either male flowers or female flowers (though some cultivars can be monoecious or hermaphroditic). So, individual papaya flowers are usually unisexual.
(2) Hibiscus (Hibiscus rosa-sinensis): Hibiscus flowers are classic examples of bisexual (perfect) flowers. They clearly show both stamens (male parts, forming a staminal tube) and a prominent pistil (female part, with stigma, style, and ovary) within the same flower.
(3) Cucumber (Cucumis sativus): Cucumber plants are typically monoecious. They produce separate male flowers (staminate) and female flowers (pistillate) on the same plant. So, individual cucumber flowers are unisexual.
(4) Maize (Zea mays - Corn): Maize plants are monoecious. The tassel at the top of the plant contains the male (staminate) flowers, and the ears (cobs) contain the female (pistillate) flowers (the silks are the stigmas). So, individual maize flowers are unisexual. Step 2: Identifying the bisexual flower From the analysis, Hibiscus is the example of a plant that typically has bisexual flowers.
