Do flatworms have internal fertilization?
No, flatworms typically reproduce through external fertilization. The male releases sperm into the water, which then fertilizes the eggs released by the female.
What is it called when sperm and eggs are released into sea water and chance contact results in fertilization?
This process is known as external fertilization. It is a method of reproduction where gametes (sperm and eggs) are released into the environment, usually water, and fertilization occurs outside of the organism's body. This is common in aquatic species like fish and amphibians.
What uses fertilization?
Frogs, fishes and amphibian animals.External fertilization is where both the eggs and sperm are released into water and the sperm is carried to the egg for fertilization. External fertilization is limited to animals living in water. These include frogs, amphibians and fish.most fish do by leaving there sperm and egg cells floating around in the water until one another meet and form a fish

What type of fertilization do animals that live in water usually show?
Animals that live in water typically exhibit external fertilization, where eggs and sperm are released into the water simultaneously. This process allows for a higher chance of fertilization due to the large volume of water, which can dilute and disperse the gametes. Common examples of aquatic animals that use external fertilization include many fish and amphibians. However, some aquatic species, like certain sharks and dolphins, may practice internal fertilization.
Why wet clothes dry up when water may be removed by evaporation?
Because liquid water is released as gaseous water.
Do bryophytes need water for fertilization?
Yes, bryophytes, like mosses and liverworts, require water for fertilization. This is because they rely on water to transport sperm from the male gametophyte to the female gametophyte for fertilization to occur.
External fertilization in animals?
External fertilization occurs when the union of egg and sperm takes place outside the bodies of the individuals involved. It is common in aquatic animals such as fish and amphibians, where both gametes are released into the water for fertilization to occur. This type of fertilization is less reliable than internal fertilization as it is subject to environmental factors such as water currents and predation.
In echinoderms could fertilization take place without water?
No because the sperm and egg cells have to be released into the water where the eggs are usually fertilized. :) ☆彡 NEON STAR
How does water aid the fertilization of some organisms?
Depending on the species, fertilization can occur internally or externally. Water aids the fertilization of some organisms because organisms that reproduce externally need water for fertilization to occur.
When does fertilization occurs during reproduction in bivalves?
Fertilization in bivalves typically occurs externally when sperm and eggs are released into the water column. The eggs are fertilized by sperm and develop into larvae that eventually settle and grow into adult bivalves.
What is internal from external fertilization?
water
