Which of the following statements is NOT part of the "Cell Theory"?
a
All cells arise from preexisting cells.
b
All cells arise spontaneously.
c
Cell is the basic structural and functional unit of life.
d
All living things or organisms are made of cells.
b
All cells arise spontaneously.
The statement "b) All cells arise spontaneously" is NOT part of the "Cell Theory".
To determine which statement is NOT part of the "Cell Theory", we need to understand what the Cell Theory states. The Cell Theory is a fundamental principle in biology that describes the properties of cells. It consists of three main statements:
1. All living things or organisms are made of cells.
2. The cell is the basic structural and functional unit of life.
3. All cells arise from preexisting cells.
Now, let's analyze each statement to identify which one is NOT part of the Cell Theory:
a) "All cells arise from preexisting cells." - This statement is consistent with the Cell Theory as it affirms that cells come from preexisting cells. Therefore, it is part of the Cell Theory.
b) "All cells arise spontaneously." - This statement contradicts the Cell Theory. According to the Cell Theory, cells do not arise spontaneously, but instead come from preexisting cells. Therefore, this option is NOT part of the Cell Theory.
c) "The cell is the basic structural and functional unit of life." - This statement aligns with the Cell Theory, as it declares that cells are the fundamental units of life. Hence, it is part of the Cell Theory.
d) "All living things or organisms are made of cells." - This statement is another core aspect of the Cell Theory, affirming that all living organisms are composed of cells. Consequently, it is part of the Cell Theory.
Therefore, the statement that is NOT part of the Cell Theory is option b) "All cells arise spontaneously."
