Question

Which of the following groups is formed of only the hermaphrodite organisms?
A. Earthworm, Tapeworm, Housefly, Frog
B. Earthworm, Tapeworm, Sea horse, Housefly
C. Earthworm, Leech, Sponge, Roundworm
D. Earthworm, Tapeworm, Leech, Sponge

Answer 1

Hint: An organism that has complete or partial reproductive organs and produces gametes normally associated with both male and female sexes are known as hermaphrodite organisms.They are also known as bisexual.

Complete step by step answer:
-Lower organisms show the hermaphrodite character.
-The great majority of tunicates, pulmonate snails, opisthobranch snails, earthworms, and slugs are hermaphrodites. Hermaphroditism is also found in some fish species and to a lesser degree in other vertebrates.
-Earthworm, tapeworm, leech and sponge shows hermaphrodite sexual characters.
Housefly, Frog, Sea horse, and Roundworm are unisexual animals.

So, the answer is D. Earthworm, Tapeworm, Leech, Sponge

Additional information:
Sequential hermaphrodites can be divided into three broad categories:
-Protandry: Where an organism is born as a male, and then changes sex to a female. Example: clownfish.
- Protogyny: Where the organism is born as a female, and then changes sex to a male. Example wrasses
-Bidirectional Sex Changers: where an organism has female and male reproductive organs, but act as either female or male during different stages in life. Example: Lythrypnus dalli

Note:
-Hermaphrodite is used in botany to describe a flower that has both staminate (male, pollen-producing) and carpellate (female, ovule-producing) parts.
-The condition is seen in many common garden plants.
-Hermaphroditism in botany means also the presence of separate male and female flowers on the same individual—such plants are called monoecious.
