Tight junction - impermeable junction that encircles the cell
Desmosome - anchoring junction scattered along the sides of cells
Gap junction - a nexus that allows chemical substances to pass between cells
Membrane junctions are specialized structures that are formed between adjacent cells, providing mechanical strength and facilitating cell-cell communication. These junctions include adherens junctions, tight junctions, desmosomes, and gap junctions, each with unique functions in cell adhesion, barrier formation, and signal transfer.
No, cell junctions are also found between animal cells. In plants, cell junctions are called plasmodesmata, while in animals they are called tight junctions, gap junctions, and desmosomes. These structures facilitate cell-to-cell communication and adhesion.
Gap junctions
The apical surface does not have any cell junctions because it is a free surface exposed to things that are not epithelial cells. The lateral surfaces of an epithelial cell, which face the adjacent cells on either side contain tight junctions, adherens junctions, desmosomes and/or gap junctions. The basal surface of an epithelial cell adhere to extracellular materials like the basement membrane. Hemidesmosomes anchor the epithelium to the basement membrane in the basal surface.
In vertebrates, there are three major types of cell junction:1. Adherens junctions, desmosomes and hemidesmosomes (anchoring junctions.)2. Gap junctions (communicating junction)3. Tight junctions (occluding junctions)Your question most likely is for the tight junction but more information in the question would be helpful.

Animal cells are mostly bound together by what are known as intercellular junctions. There are three types of cell junctions: anchoring junctions, tight junctions and gap junctions. Of these, anchoring junctions, which include adherens junction, desmosomes and hemidesmosomes, help bind the animal cells together, in an extracellular matrix.

All cells have a cell membrane! Only "plant cells" have a cell wall, and a cell membrane!

depend on the kind of cell...... plant: cell wall and cell membrane/plasma membrane animal: cell membrane/plasma membrane
The main organelles responsible for cell-cell connections are the plasma membrane and gap junctions. The plasma membrane, made of lipids and proteins, allows cells to physically connect with each other. Gap junctions are specialized protein channels that allow for direct communication between adjacent cells by allowing the passage of ions and small molecules.
Gap junctions are membrane junctions that allow for the passage of small molecules, ions, and nutrients between adjacent cells. They are made up of specialized proteins called connexins that form channels connecting the cytoplasm of neighboring cells. This direct communication plays a crucial role in coordinating cellular activities within tissues and organs.
Gap junctions allow direct cell-to-cell communication by forming channels between adjacent cells. These channels enable the passage of ions and small molecules, facilitating the transmission of signals and coordination of cellular activities.
