What do two earthworms exchange during mating explain why?
During mating, two earthworms exchange sperm with each other. Each worm has a clitellum, a thickened band that produces a mucus sheath to protect the fertilized eggs. This exchange allows both worms to have a supply of sperm for fertilization, increasing genetic diversity in their offspring. After mating, each worm can fertilize its eggs using the sperm received from its partner.
Where is navel of earthworm present?
It doesn't have one ! Earthworms are hermaphrodites - possessing male and female reproductive systems. During 'mating' they exchange sperm with each other. Subsequently, they both lay eggs which develop into tiny worms.
Do earthworms mate for life?
No, earthworms do not mate for life. They reproduce sexually by copulating with another earthworm in order to exchange sperm. After mating, each earthworm goes its separate way to continue its activities.
What do you mean by asexual reproduction?
It means something that produces both sperm and eggs. Take for example the earthworm. It produces eggs and sperm but CANNOT fertilise itself. During 'mating' two worms exchange sperm so they fertilise each other.
What do two earthworms exchange during mating?
During mating, earthworms exchange sperm and eggs. The exchange occurs through a process called copulation, where the two worms line up ventral to ventral and exchange gametes. This exchange allows for fertilization to occur internally within the worms' bodies.
Does an earthworm have to produce sperm and egg for fertilization to occur?
No, earthworms are hermaphrodites, which means they have both male and female reproductive organs. They can produce both eggs and sperm, and fertilization can occur when two earthworms exchange sperm during mating.
How do lions exchange gases?
by mating
What is the saddle of a earthworm for?
It holds the male and female reproductive organs.
What is the function of an earthworm's seminal vesicals?
Seminal vesicles in earthworms store and release sperm during copulation. They play a crucial role in the reproductive process by providing a reservoir for sperm to be transferred to the female during mating.
What is Sexual orientation of earthworms?
Earthworms are hermaphroditic, meaning each individual possesses both male and female reproductive organs. They can produce both sperm and eggs, allowing them to mate with other earthworms to exchange sperm and increase genetic diversity. During mating, earthworms align their bodies and exchange sperm, which can later be used to fertilize their own eggs. This unique reproductive strategy helps ensure the survival and adaptability of earthworm populations.
What is the lighter colored flattened part of the earthworm?
The lighter colored flattened part of the earthworm is called the clitellum. It is a thickened, glandular region of the body that plays a crucial role in reproduction, as it secretes mucus during mating and forms a cocoon for fertilized eggs. The clitellum is typically more prominent in mature earthworms and can be seen as a band around the body.
Where does gas exchange and water loss occur in plants?
By opening and closing the stomata on the underside of the leaves.
