Define the terms unisexual and bisexual giving one example of each.
Answer:
Unisexual: In most of the animals including humans, male and female reproductive organs are in different individuals. Such animals are called unisexual.
Bisexual: In some animals like tapeworm, liver fluke, earthworm, leech, etc., the male and female reproductive organs are found in a single individual. Such organisms are called bisexual (hermaphrodite).
The flower may be unisexual (e.g., papaya, watermelon) when it contains either stamens or carpels and bisexual {e.g., Hibiscus, mustard) when it contains both stamens and carpels.
