The cell membrane is a phospholipid bilayer that is described as a "Fluid Mosaic." The mosaic consists of various glycoproteins and also cholesterol.
The phospholipid bilayer contains phosopholips, which are composed of a unit of glycerol, two hydrophobic fatty acids and a hydrophilic PO4 head. Glycolipids and glycoproteins, collectively the Glycocalyx, are on the surface and involved in cell signalling. Cholesterol helps regulate fluidity. Intrinsic proteins (such as aquaporins) facilitate diffusion and extrinsic proteins are involved in active transport.
The two major types of cells are prokaryotic cells, which lack a nucleus and membrane-bound organelles, and eukaryotic cells, which have a nucleus and membrane-bound organelles. Eukaryotic cells are found in plants, animals, fungi, and protists, while prokaryotic cells are found in bacteria and archaea.
The cell theory is supported by the fact that the cell membrane, cytoplasm, and genetic material can be found in all types of cells.
The cell membrane is found surrounding the outer boundary of the cell, acting as a barrier between the cell's internal environment and the external environment. It is present in all types of cells, including animal cells, plant cells, and bacterial cells.
Cells found in epithelium that secrete mucus are primarily goblet cells. These specialized epithelial cells are scattered throughout various types of epithelial tissues, particularly in the respiratory and intestinal tracts. Goblet cells produce and release mucus, which serves to lubricate and protect surfaces, trap particles, and facilitate the movement of materials. Their presence is crucial for maintaining the health and functionality of these epithelial linings.
Goblet cells secrete mucus, a viscous fluid composed primarily of highly glycosylated proteins called mucins suspended in a solution of electrolytes.Goblet cells.
Goblet cells are typically found in the epithelial lining of the respiratory tract, gastrointestinal tract, and conjunctiva of the eye. These cells secrete mucus to protect and lubricate these tissues.
Bacteria cells lack a true nucleus and membrane-bound organelles, which are found in other types of cells.

Eukaryotic cells are found in plants, animals, fungi, and protists, while prokaryotic cells are found in bacteria and archaea.
The Two types of cells are prokaryotes and eukaryotes. Prokaryotic cells are simple cells, that have no membrane bound organelles, the prokayotes cells act as the whole organism, such as bacteria. Eukaryotes on the other hand are found in mulitcellular organisms. These, cells, have membrane bound organelles and a nucleus.

They are any cells with a membrane bound nucleus.
The three basic types of cells are prokaryotic cells (lacking a nucleus and membrane-bound organelles), eukaryotic plant cells (containing a nucleus and membrane-bound organelles), and eukaryotic animal cells (also containing a nucleus and membrane-bound organelles).
