The evolution of a coelom allowed organs to be cushioned and to grow and move independently of each other. It also appears to have evolved with a complete digestive system, which is an advantage, because it allows nutrients to be extracted from food much more efficiently.
1. the ability for larger organs to grow independently fort eh mesoderm lined wall 2. the storage of sperm and eggs
the answer is gene flow
No. A coelenterate is an animal (such as a jellyfish), whose main body cavity is also its alimentary canal (gut). Most animals, on the other hand, have a body cavity (called a coelom) that is separate from the gut. For instance, inside your own body, you have an alimentary canal (your esophagus, stomach and intestines) and a separate body cavity that contains your heart, lungs, liver, etc. In a coelenterate, there is only one cavity.
Acoelomates is the name given to animaks which lack a coelom. Coelom is true body cavity which is formed in mesoderm by different methods e.g. schizocoelous or enterocoelous.Coelom is lined by mesodermal epithelium . Phylum Platyhelminthis is included in acoelomates. Pseudocoelomates possess a pseudocoelom while coelomates possess a true coelom.
ns present in the coelom
flatworms are the only triploblastic organisms that lack a coelom
It can act as a hydrostatic skeleton
The presence or absence of a coelom (body cavity) is a key characteristic in the classification of animals. Animals can be categorized as acoelomates (no body cavity), pseudocoelomates (body cavity between mesoderm and endoderm), or coelomates (body cavity within mesoderm). This classification is important in understanding the evolutionary relationships and anatomical differences among animal groups.
the answer is gene flow
what benfit do animals derive from having a coelm
The coelom is the body cavity of an animal. A true coelom is a body cavity that is complete from mouth to anus with no breaks; there are animals that have pseudocoeloms - mouths and anuses but no solid connection between the two.
exists in all animals.
Polycheats Annelids were first animals to develop a true coelom .
Depending upon the coelom, the animals are divided into1)Acoelomates - Eg: Platyhelminthes2)Pseudocoelomates Eg: Nematyhelminthes3)Eucoelomates: - Eucoelomates are further divided into two typesa) Schizocoelom -Eg: Annelida, Arthropoda, Molluscab) Enterocoelom -Eg: Hemichordata and Chordata
false
no
it does not have a coelom.
