New cards
23
No pattern of symmetry in an organism.
What is asymmetry?
New cards
24
Symmetry that is based around a center point, like starfish.
What is radial symmetry?
New cards
25
Symmetry where both organisms have the same left and right side, but their internal organs aren’t the same (like humans).
What is bilateral symmetry>?
New cards
26
It’s the anterior concentration of sense organs, basically the organism has a head, usually with eyes, nose and other sense organs, plus a brain
What is Cephalization?
New cards
27
Segments of the body become specialized for specific purposes, like a bee.
What is Segmentation?
New cards
28
Backside of an organism.
What is the Dorsal side?
New cards
29
The abdominal or “belly side” of an organism.
What is the Ventral side?
New cards
30

What is the Anterior side?
New cards
31
Opposite of the head or the “rear” of organism with bilateral symmetry.
What is the Posterior side?
New cards
32

New cards
33

What determines if an organism is deuterostome or protostome?
New cards
39
An opening for solid waste removal from digestive tract.
What is the anus?
New cards
