Invertebrates And Vertebrates

Front 1

gastrulation

Back 1

cells migrating to the interior of the blastula

Front 2

larva

Back 2

sexually immature and morphologically distinct from the adult eventually undergoes metamorphosis

Front 3

metamorphosis

Back 3

the process by which an animal physically develop after birth or hatching, involving a relatively abrupt change in animal's body structure

Front 4

body plan

Back 4

a set morphological and developmental traits integrated into a living animal, categorized in morphological traits including: symmetry, tissues, body cavities

Front 5

radial symmetry

Back 5

symmetrical all the way around

Front 6

bilateral symmetry

Back 6

only symmetrical down the middle

Front 7

ectoderm

Back 7

the germ layer covering the embryo's surface

Front 8

endoderm

Back 8

the innermost germ layer

Front 9

diploblastic

Back 9

animals have ectoderm and endoderm

Front 10

tribloblastic

Back 10

animals also have an intervening mesoderm layer

Front 11

coelomates

Back 11

animals that possess a true coelom, a true body cavity and is derived from the mesoderm, organs are well organized

Front 12

pseudocoelomates

Back 12

animals that possess a pseudocoelm, a body cavity derived from mesoderm and endoderm, organs are held loosely

Front 13

acoelomates

Back 13

animals that lack a body cavity

Front 14

sponges

Back 14

sedentary animals that live in both fresh and marine waters, they lack true tissues and organs , are suspension feeders, and hermaphroditesthis

Front 15

suspension feeders

Back 15

sponges are this type of feeder, capturing food particles suspended in the water that pass through their body

Front 16

hermaphrodites

Back 16

individuals that function as both male and female

Front 17

alimentary canal

Back 17

rotifers contain this, a digestive tube with a seperate mouth and anus lies within a fluid-filled pseudocoelom

Front 18

parthenogenesis

Back 18

rotifers reproduce by an asexual reproduction in which females produce offspring produce offspring from unfertilized eggs

Front 19

metamorphosis

Back 19

the process by which an animal physically develops after birth or hatching, involving a relatively abrupt change in animals body structure

Front 20

incomplete metamorphosis

Back 20

the young resemble adults but are smaller and lack adult features such as wings and genitalia

Front 21

complete metamorphosis

Back 21

insects with this have a complete larval stage and enter an inactive state called pupa and then emerge as adults
