Which of the following is NOT a type of cell membrane junction?
A
Gap junction
B
Plasmodesmata
C
Tight junction
D
Desmosome
Verified step by step guidance1
Understand the context: Cell membrane junctions are structures that connect cells together, allowing communication, adhesion, or barrier formation between cells. These junctions are crucial for maintaining tissue structure and function.
Review the types of cell membrane junctions in animal cells: Gap junctions, tight junctions, and desmosomes are all types of cell membrane junctions found in animal cells. Each has a specific role: gap junctions allow communication, tight junctions create barriers, and desmosomes provide mechanical strength.
Identify the outlier: Plasmodesmata are not a type of cell membrane junction in animal cells. Instead, they are structures found in plant cells that allow communication and transport of materials between adjacent plant cells.
Compare the options: Gap junctions, tight junctions, and desmosomes are all valid types of cell membrane junctions in animal cells, while plasmodesmata are specific to plant cells.
Conclude: The correct answer is 'Plasmodesmata' because it is not a type of cell membrane junction found in animal cells, but rather a structure unique to plant cells.
