Students have asked these similar questions
The basic body plan of a mollusk is to have a head, foot, and visceral
mass. In the case of the cephalopods, the foot;
Has become part of the digestive system
Has been modified into a beak
Has been modified into tentacles
Has been modified into part of the respiratory system
ILLUSTRATE THIS/
Mollusks are divided into three classes: Class Cephaloda (squids), Class Gastropoda (snails), Class Bivalvia (clams and oysters)
Cephalopods have a few orders, one of which is order octopoda ( octopus) and the other is order teuthida ( squids)
the scientific name for the common octopus is octopus vulgaris
the scientific name for the common squid is loligo vulgaris
A radula in a gastropod is
a female reproductive structure
A sharp, tooth like structure for killing prey
a structure that aids in feeding
a sense organ for detecting light
Which choice correctly identifies the body plan of a Mollusc?
radial symmetry
bilateral symmetry
asymmetry (no symmetry)
