Sponges have specialized cells and an endoskeleton, but they lack tissues and body symmetry. ... They include jellyfish and corals, both of which have radial symmetry. All cnidarians have nematocysts, and many are bioluminescent. They may exist in medusa and/or polyp form.
Plasma membrane is a part of the cell made of a lipid bilayer and an embedded protein layer. It protects the cell from the surroundings and also controls the materials leaving or entering the cell. The membrane is semipermeable and therefore allows certain materials to enter or leave the cell. In this case, the plasma membrane may prevent unlimited flow of water into or out of the cell.

DNA is synthesized in the middle part of Interphase, which is usually denoted S in the series G1 - S - G2 </span><span>"There are 3 stages of interphase: G1 in which the cell grows and functions normally. Once it grows too large it enters the synthesis (S) phase. In S phase the cell makes exact copies of its DNA. It is now ready for G2 phase where it makes sure all of its chromosomes and organelles are ready for mitosis."</span>
