Unit 3 Test. Cells and Cytology

Question 1 of 23

1

The cell theory states that the cell is the mst basic unit of life, all organisms are made of cells and all cells come from cells. What makes the cell theory a scientific theory?

Select one of the following:

  • It is based on a scientific publication that is read by scientists worldwide.

  • It is based on the work of many scientists and leads to accurate predictions.

  • It is based on ideas that have been proven true and that are not subject to revision.

  • It is based on preliminary evidence but still needs to be confirmed with experiments.

Explanation

Explanation

Question 4 of 23

1

What are the folds in the Golgi Apparatus called?

Select one of the following:

Explanation

Question 5 of 23

1

The cell membrane maintains homeostasis and is made of a combination of phospolipids and proteins.

Select one of the following:

  • True
  • False

Explanation

Question 6 of 23

1

Why is the cell membrane made of phospolipds and proteins?

Select one of the following:

  • The phospholipids prevent the membrane from dissolving and the proteins aid in semi-permeability.

  • Phospholipids have little oxygen and proteins cause enzyme catalyzed reactions.
