Cell Communication

cells generating, transmitting, receiving, and responding to chemical signals

New cards

Direct Contact

cells communicating by coming into physical contact with each other to relay a message

  • connected cytoplasm of two adjoined cells

    • plants: plasmodesmata

    • animals: gap junctions

  • immune response

Local Regulators

cells communicating in a local area

  • paracrine signaling: cells secrete short lived chemical signals to local cells to elicit a joined response

    • neurotransmitters

Long distance

cell communicating through long distances

  • endocrine system: production of hormones by glands which travel through circulatory system

Contact Inhibition

Cells divide to create layers

  • once the cell layers touch another cell, cell division stops
