All animals belong to
Protozoa
Parazoa
Eumetazoa
Metazoa
The first animals probably evolved from a
bacterium
an autotrophic prokaryote
fungus
flagellated protist

radial symmetry
bilateral symmetry
a pseudocoelom
a blastopore
In deuterostomes, blastopore becomes anus
True
False
What is NOT true about animals?
they are multicellular
they can be autotrophs or heterotrophs
they are eukaryotic organisms
they exhibit diverse modes of feeding
Diploblastic animals do not have
true tissues
endoderm
ectoderm
mesoderm
What is a common trait of animals, plants, and fungi?
absorptive nutrition
alternating generations
they are all eukaryotic
they are all heterotrophs
A cell wall is found in
plants only
plants and bacteria
fungi and bacteria
plants, fungi and bacteria
Parazoa (eg. sponges) have
bilateral symmetry
radial symmetry
no symmetry
a true coelom
This type of cell is absent from Sponges:
amoebocytes
sclerocytes
choanocytes
muscular cells
Sponges get their nutrients, as all animals do, through absorptive nutrition
True
False
Sponges and their larvae (young offspring) are sessile
True
False
Jellyfish and anemones
have true tissues
are tribloblastic
do not have symmetry
belong to Porifera
What is NOT a trait of radiata
digestion occurs inside the cells
have tentacles surrounding the mouth
have nerve cells
they are diploblastic
What is NOT true about Ctenophora:
They have two long tentacles
They have a complete gut
They have stinging cells
