What are Colloblasts/sticky cells?
This part of the body is soft and holds most of the vital organs.
What is the Visceral mass?
This key trait helps Arthropods move freely while keeping a hard exoskeleton.
What is a segmented body plan?
_____ is the movement of molecules in and out of a cell from high to low concentrations.
What is Diffusion?
This structure is responsible for water flow, respiration, and reproduction.
What is the Osculum?
This body plan of Cnidarians swim freely in the water.
What is the Medusa body plan?
Almost all organisms in this phylum has some form of this rigid structure.
What is a shell?
