DNA & rna
The sac or the small cavity that contains materials in a eukaryotic cell is called vesicle. The vesicle is covered by a membrane called lipid bilayer.
mabey the nucleous
All eukaryotic cells have a membrane covered compartment called the nucleus. The nucleus is the control center of the cell and contains the cells DNA.
The pharynx is covered by a mucous membrane that helps protect and lubricate the tissues in the throat. This membrane also contains specialized cells that help trap and remove foreign particles, such as bacteria and viruses, to prevent infections.
Membrane covered organelles.
Vacuoles, I think. They bud off of the Golgi Complex to transport materials around or out of the cell.
the rib cage
The vacuole.
EndoPlasmic Reticulum
Plant cells do have cell membranes, which are covered by the cell walls.
The structure being described is the nuclear envelope, which surrounds the cell's nucleus. It consists of two lipid bilayers and contains nuclear pores that regulate the passage of molecules in and out of the nucleus.
Scientifically explaining, they are membrane-covered organelles that are found only in the eukaryotic cell. Prokaryotic cells do not have membrane-covered organelles. The only organelle they have, not membrane-covered, are ribosomes.
