The phylum Cnidaria is comprised of animals that are radially symmetrical and have a jellylike material, called mesoglea, between two layers of cells.
nucleus
Symmetry is used to classify animals based on their body structures and organization. Animals can be classified as having radial symmetry (body parts arranged around a central axis) or bilateral symmetry (having a left and right side that are mirror images). Symmetry helps scientists understand the evolutionary relationships between different animal groups.
Cytoplasm is the jellylike material found within the cell membrane. This substance, which is made mostly of water, protects the organelles inside the cell, such as the Golgi body/apparatus, endoplasmic reticulum, and the nucleus.
The jellylike fluid between the cell membrane and the nucleus is called the cytoplasm. It contains various organelles, such as mitochondria and ribosomes, that are essential for the cell's functions. The cytoplasm also serves as a medium for transporting nutrients and waste within the cell.
The space between the cell membrane and the nucleus is filled with cytoplasm, which contains organelles like mitochondria, endoplasmic reticulum, and ribosomes. It also serves as a medium for various cellular processes to take place, such as protein synthesis, metabolism, and transportation of molecules within the cell.
The supporting material in a jellyfish's skeleton is a jellylike mass that fills the space between two tissue layers.
Mesophyll
Not really. For example, there are infinitely many shapes with lateral (left-right) symmetry - including very many animals.

Cubazoa are a group of cnidarians. Cnidarians are animals that have radial symmetry and are usually venomous or poisonous.
Bilaterally symmetric animals have a central nervous system.
Approximate Symmetry is approximately symmetrical. Regular Symmetry is Symmetrical for sure.
Lines of symmetry are 2 dimensional. Planes of symmetry are 3D.
The Cytoplasm
The jellylike substance you are referring to is called cytoplasm. It is where cell organelles are suspended and where many cellular processes take place.
A symmetrical shape is said to have line symmetry. A shape that has line symmetry can have one or more lines of symmetry
