Explain the difference between diploblastic and triploblastic?
triploblastic : organisms which have three layers in the embryo : the ectoderm,mesoderm & endoderm
What is the name of lower Invertebrates that have a jelly-like layer between endoderm and ectoderm?
Cnidarians secrete mesoglea - which is a jelly-like substance that separates the ectoderm and endoderm.
What is a gel-like substance located between the endoderm and the ectoderm?
mesoglea ;)
A pseudocoelom is a body cavity located between the endoderm and the mesoderm?
false.
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.

What exactly is meant by the term mesoderm?
The mesoderm refers to one of the three germ layers that develops when an animal is in the embryo stage. It is in between the ectoderm and the endoderm.
Difference between Diploblastic and triploblastic embryo development?
the body of diploblastic animals consists of two layers of cells, ectoderm and endoderm. there is a jelly like mesenchyme or mesoglea, between the two layers, which in most cases is non cellular. the body of triploblastic animals is made of three layers ectoderm, endoderm and mesoderm.
Are jellyfish diploblastic?
They are triploblastic because they are apart of the phyla Echinodermata. If you look at the animal phylogenetic tree you can see that starfish are apart of the triploblasts. The difference between diploblastic and triploblastic is that diploblastic have two germ layers during development which are the ectoderm and endoderm. Triploblastic animals (like starfish, and humans) have three germ layers which are the ectoderm (outside), mesoderm (middle) and endoderm (inside).

Cnidarians secrete mesoglea - which is a jelly-like substance that separates the ectoderm and endoderm.

false.
What does the ectoderm form?
The Ectoderm is the start of a tissue that covers the body surfaces. It emerges first and forms from the outermost of the germ layers.The Ectoderm forms: the central nervous system, the lens of the eye, cranial and sensory, the ganglia and nerves, pigment cells, head connective tissues, the epidermis, hair, and mammary glands
