Lesson 5 Homeostasis and Cellular Processes

What is the definition of homeostasis?

• Process by which energy from sun is used to make food

• elimination of wastes

• division of cells to form new cells

• the maintenance of a stable internal environment

Which of the following must all cells do to survive?

• continue growing

• obtain energy

• absorb wastes

• utilize oxygen

Which statement best describes the process of mitosis?

• One cell splitting into numerous cells in order to maintain homeostasis.

• One cell splits into two cells, each with half the number of chromosomes as the original cell.

• One cell splits into two cells, each with the same number of chromosomes as the parent cell.

• Two cells join together by sharing genetic information.
