Amanda Balash 7.1 Section Review 1. Explain how the jellyfish is adapted for floating? The jellyfish has a jellylike mass called a mesoglea that enables the jellyfish to float because of its shape and thinness of the membrane. 2. How do jellyfish capture and digest their prey? The jellyfish have stinging cells called cnidoblasts. Inside each of these is a coiled thread with a barb at the end called a nematocyst. There is usually a toxin in the nematocyst to paralyze their prey so that the tentacles can bring the food to its mouth. It is ingested in the mouth in the center of the medusa. Most of the food is ingested in saclike digestive cavity by enzymes secreted by its lining. Digestion occurs in the digestive sac and in the food vacuoles. 3. Describe how a typical jellyfish reproduces? Jellyfish’s life cycle include an asexual and sexual phase. During the sexual phase, the sperm are produced in the teste and spit out of the male’s mouth and into the female’s mouth.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
