Chapter 7.4 Homeostasis and Cells

Question 1

How do individual cells maintain Homeostasis?

Answer 1

To maintain homeostasis, unicellular organisms grow, respond to the environment, transform energy, and reproduce.

Question 2

What is Homeostasis?

Answer 2

(“Home(o)” = similar) (“stasis” = stopping/standing) the relatively constant internal physical and chemical conditions.

Question 3

How do cells of multicellular organisms work together to maintain homeostasis?

Answer 3

the cells of multicellular organisms become specialized for particular tasks and communicate with one another to maintain homeostasis.

Question 4

What are the levels of organization for multicellular organisms?

Answer 4

specialized cells group into Tissues that perform a particular function. Specific tissues group into Organs which have different kinds of tissues that work together. Organs that work together form Organ Systems.

Question 5

What is a Receptor?

Answer 5

an area on the outside of a cell that can bind to the chemical signals sent from other cells as a form of communication.
