Answer 1

delete meow hi raya

Question 2

What are the main ways cells communicate?

Answer 2

Cells communicate by:
1. Direct contact (cell-cell signaling)
3. Short distance communication
3. Long distance communication

Question 3

How do some unicellular organisms maintain survival in some condiitons?

Answer 3

By maintaining physical contact with one another and making colonies

Question 4

How can cells send messages to cells that are really close?

Answer 4

Sending chemical signals (local regulators)

(short-distance cell communication to usually the same cell type)

Question 5

By what means can cell-cell communication occur?

Answer 5

Cell wall and cell membrane modifications can occur to allow for cell-cell communication

Question 6

What faclitates cell-cell communication in plants?

Answer 6

Plasmadesma(ta)

Question 7

What faclitates cell-cell communication in animals/humans?

Answer 7

Gap junctions

Question 8

How can cells send messages to cells that are really far?

Answer 8

Chemical signals

(long-distance communication, usually to a cell of a different type)

Question 9

How can cells send messages to cells that are really far and really close?

Answer 9

Chemical signals baby

Question 10

What is the cell that is recieving the signal(s) called?

Answer 10

The target cell

Question 11

What’s an example of cells that communicate through cell-cell contact and how?

Answer 11

Immune cells through extracellular sttucture that fit together

Question 12

What’s an example of cells that communicate through local cell signaling?

Answer 12

Neurotransmitters, using exocytotic vesicles that release signals
