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.
A mesoderm is a middle layer of the zagote(one of three layers)
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.

Earthworms are Coelomates. They posses a true coelom, which is a body cavity that is completely lined by tissue derived from the mesoderm. This body cavity can either be empty air-filled space separating the digestive tract from the outer body wall, or fluid-filled space. Since triploblastic animals are defined as animals having three germ layers, earthworms is considered a triploblastic animal for it possess a endoderm, a mesoderm, and a ectoderm.
Mesoderm, specifically the visceral mesoderm layer consisting of mesoderm and endoderm.

Triploblastic. Google said so. Also, I cut one open and checked.
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.
An animal derived from only two germ layers are called diploblastic animals. Eg: Poriferans, Coelenterates.

mesoderm The mesoderm forms: skeletal muscle, the skeleton, the dermis of skin, connective tissue, the urogenital system, the heart, blood (lymph cells), the kidney, and the spleen.
Chorda mesoderm, also known as the notochord, is a structure found in the embryos of chordates. It provides structural support and is involved in early development of the central nervous system. The notochord is eventually replaced by the vertebral column in vertebrates.
