Introduction to Cells Review 3.1

Homeostasis

The cells need to extract energy from food in order to maintain the homeostasis.

Multiple Choice

The _______________ need to extract energy from food in order to maintain the___________.

• cells, homeostasis

• atoms, homeostasis

• molecules, homeostasis

• tissues

Multiple Choice

The cell need to extract __________ from food in order to maintain the___________.

• energy, homeostasis

• shape, homeostasis

• character, homeostasis

Homeostasis allows cells to reproduce, get energy, nutrients & remove waste.

All living organisms have/need homeostasis because they all have cell membranes

Multiple Choice

• be faster

​The purpose of Homeostasis is to …

1.Obtain and use energy

2.Make new cells

3.Exchange material (such as nutrients)

4.Eliminate waste
