Cell-cell recognition involves direct contact between cells. Synaptic signaling requires the nerve cell to be very close to the target cell. Plasmodesmata in plant cells is a junction that allows molecules to pass between adjacent cells with out having to cross the plasma membrane. Hormones are used by plants and animals for long-distance.

AP Question 2 Proteins functioning as enzymes exhibit precise specifications. Discuss the levels of structural organization within proteins which are responsible for specific molecular interaction. AP Question 3 Suppose that you have isolated an extract from a tissue and you have found that the extract speeds up the rate of a particular reaction.
Cell Signalling. Cells need to interact with their environment and other cells around them. This is called Cell Signalling.Single cellular organisms need to detect nutrients in their environment, and cells in multicellular organisms are involved in a complex system of communication with each other. Cells detect signals with Cell Receptors on their plasma membrane, which are usually.
