Flatworms have mesoderm which forms muscle tissue and reproductive organs but there is not body cavity between the gut and the outer body walltherefore they are called what?
at a organ level of organization and they are acoelomates.
Do flatworms have no coelom a pseudocoelom or a true coleom?
no
What organ systems are formed from the germ layers?
Mesoderm, specifically the visceral mesoderm layer consisting of mesoderm and endoderm.
What does a flatworm have inside its body?
Flatworms and Roundworms have bilateral symmetry as a body type.
How many germ layers do annelids have?

What are the three germ layers of a gastrula?
From inner to outer, the germ cell layers are the endoderm, mesoderm, and ectoderm. Each of the three layers develops into a different part of the embryo: the endoderm into the respiratory, auditory, and digestive system; the mesoderm into the skeleton and muscles; and the ectoderm into the skin, tooth enamel, and nervous system.
What is mesoderm?
A mesoderm is a middle layer of the zagote(one of three layers)
What three systems developed in the mesoderm of planarians?
The three systems that developed in the mesoderm of the planarians are ectoderm, mesoderm, and endoderm. They are usually described as the three germ layers.
Compare and contrast the body of a flatworm to the body plan of a roundworm?
Flatworms are considered acoelomate, since they have no body cavity, and roundworms are pseudocoelomate because they have a body cavity, but it is not derived from the splitting of the mesoderm tissue. Also, flatworms only have one opening in their digestive system unlike roundworms with two.
Does a diploblast have a mesoderm?
no
What are facts about flatworms?
facts about flatworms
Chordates have a true body cavity called a?
yes, I think it's called coelom. An organism with a true body cavity is called a eucoelomate. This means that the body cavity exists between the inner layer of mesoderm and the outer layer of mesoderm. A pseudocelomate kind of has a body cavity but it is the space between the endoderm and mesoderm. This is not a true body cavity because it is not mesoderm on mesoderm.
