Match the following correctly

Description	Term
1. A protein structure that creates direct channels from the cytoplasm of one cell to the cytoplasm of an adjacent cell.	A. Adherens junction
2. Anchoring junction that connects actin filaments in one cell to those in the next cell.	B. Cadherin
3. A member of a family of proteins that mediate Ca2+-dependent cell-cell adhesion in animal tissues.	C. Plasmodesmata
