"Cephalization" means that the animal has a defined "head" region in which there is a lot of nervous tissue (such as the brain in humans). Sponges are not cephalized because they do not have defined head region nor do they have a central location for their nervous system. The nervous system in sponges is very loose because their cells generally work more individually as opposed to being commanded by a nervous system.
Nope sponges do not haveCephalization because sponges do not have
organs, nervous control,
head and brain,etc.
no because they are asymmetrical.
No
The cephalization of a mollusca could possibly describe the arrangement of neurons in the front end of the animal.
Cephalization
A hydra does not have cephalization.
Cephalization means formation of a head. Cnidarians have no head, so no.
Animals with cephalization respond more quickly and in more complex ways.
Yes. They have extensive cephalization. They have a brain and eyes.
they do not

A sponge.
Cephalization refers to the gathering of neural tissue towards the anterior or posterior for means of central control. In arthropods, cephalization has formed the brain in the head of the animal, usually consisting of the first three ganglia of the paired nerve cords.
Cephalization. Shouldn't you be reading your textbook?
