Acoelomates
W/out a coelom. There is no cavity between the body wall and organs
Pseudocoelomates
False coelom. The blastocoel remains and forms a body cavity.
Coelomates
Have a true coelom which is a body cavity lined with mesodermal tissues.
Schizocoely
The coelom develops from a split in the mesoderm. This occurs in protostomes
Enterocoely
The coelom develops from the archenteron (embryonic gut). This occurs in dueterostomes.
Triploblastic
All three germ layers are developed in the blastula
(ectoderm, endoderm, mesoderm)
Dipolbastic
Only two germ layers are developed in the blastula (ectoderm and endoderm)
Spiral Cleavage
Embryonic cleavage in which cleavage planes are diagonal to the polar axis.
Radial Cleavage
Embryonic development in which early cleavage planes are symmetrical to the polar axis.
Monoecious
Having both male and female parts
Dioecious
Having either males OR female parts
Antiparallel
The strands line up in a 5-3 form connected to a 3-5 form. The 3-5 is upside down in comparison to the 5-3
Complimentary
The nitrogenous base on one strand must compliment the nitrogenous base on the other
