describe the life cycle of a jellyfish. make sure to use the words polyp and medusa.

When jellyfish are attached to coastal reefs they have a stalked (polyp) phase and a jellyfish (medusa) phase, when they float among the plankton. The jellyfish eggs are fertilized internally and develop into free-swimming planula larvae during the medusa stage. The medusa stage is the reproductive stage. The larvae will then settle on the sea floor after a brief period of floating around the water surface. The larvae will attach themselves at one end, there they then develop into polyps and grow. During the months of spring, some of the polyps will start to bud off immature jellyfish also knows as ephyra larvae. They then grow into mature jellyfish. :)

An autotrophic protist - they can perform photosynthesis and mainly consist of unicellular algae. they can be divided into number of systematic group according to the shape of their cell and the type of photosynthetic pigments they use.
