Tight junctions
Membrane proteins creating leak-proof barriers between cells, preventing substances from seeping through.
Anchoring junctions
Intermediate filaments using complex protein structures to anchor neighboring cells together.
Desmosomes
Another term for anchoring junctions, linking cells with protein structures but not leak-proof.
Gap junctions
Protein channels connecting cytoplasm of two animal cells, allowing nutrient exchange.
Plasmodesmata
Gaps in plant cell walls connecting cytoplasm of neighboring cells for nutrient exchange.
Membrane proteins
Proteins in cell membranes involved in forming tight junctions for leak-proof barriers.
Intermediate filaments
Protein structures in anchoring junctions that link neighboring cells together.
Protein channels
Structures in gap junctions creating pathways for exchange between cell cytoplasms.
Cytoplasm
Cellular material connected by gap junctions or plasmodesmata for substance exchange.
Cell walls
Structures in plant cells containing plasmodesmata for cytoplasmic connections.
