A spiral galaxy.
A grand design spiral galaxy (like Whirlpool Galaxy) has prominent and well defined spiral arms, whereas a flocculent galaxy (like Sunflower Galaxy) has short segments of spiral structure, "fluffy" in appearance, but without the dramatic well defined spiral arms of a grand design spiral.

Exemples of properties: structure, cell dimensions, lattice energy.

A cell with a well-defined nucleus surrounded by a nuclear envelope is a eukaryotic cell. Eukaryotic cells are characterized by their complex structure, which includes membrane-bound organelles, such as the nucleus, where the cell's genetic material is housed. This distinguishes them from prokaryotic cells, which lack a true nucleus and nuclear envelope. Examples of eukaryotic cells include plant cells, animal cells, and fungal cells.
There is no such thing as a "porkaryotic cell." It seems to be a typo. The correct term is "prokaryotic cell," which is a type of cell that lacks a well-defined nucleus and membrane-bound organelles. Prokaryotic cells are simpler in structure compared to eukaryotic cells.

Its structure is oval shaped but there are various other shapes as well.
