General Biology II Exam 2 Part 1

Front

What is cell communication?

Back

It is how a cell sends, receives, and responds to messages.

Front

What does cell communication allow a cell to do?

Back

Respond to its chemical and physical environment.

Front

Why is cell communication important in multicellular organisms?

Back

A)

Responds to changes in the external environment

B)
Responds to changes in the internal environment and maintain homeostasis

C)

Run systems (Ex.: Immune System)

Front

What are some specific responses of cells to cell communication?

Back

1) Cell Division

2) Maturation

3) Apoptosis

4) Other Signal Production

5) Cell Activation

6) Cell Shape Change

7) Mating

Front

Why study cell communication?

Back

1) Understand cells and system work

2) Explain some diseases like cancer and diabetes

3) Make drugs that use signaling pathways.

Front

What is homeostasis?

Back

The ability to maintain a stable internal environment.

Front

How is cell communication involved in homeostasis?

Back

It allows cells to respond to internal changes and maintain homeostasis.

Front

Why is homeostasis important in the body?

Back

It keep systems, such as the immune system, running in different environments.

Front

List the types of stimuli that cells can respond to

Back

1) Chemical

2) Mechanical Force
3) Other Cell Contact

4) Gravity

5) Change in voltage across membrane

6) Change in Light

7) Change in Pressure

Front

What are the three types of cell signaling in plants and animals?

Back

1) Direct Signaling

2) Local Signaling

3) Long Distance Signaling
