Question

Select all the components of cell theory as outlined by Schleiden, Schwann, and Virchow:

A) Cells are the basic unit of life.
B) All living organisms are composed of cells.
C) Cells arise spontaneously from non-living matter.
D) All cells come from pre-existing cells.

Answer 1

The correct components of cell theory, as outlined by Schleiden, Schwann, and Virchow, are that cells are the basic unit of life, all living organisms are composed of cells, and all cells come from pre-existing cells. 'Cells arise spontaneously from non-living matter' is not a part of the cell theory. the correct answers are A) Cells are the basic unit of life, B) All living organisms are composed of cells, D) All cells come from pre-existing cells.

Step-by-step explanation:

The question asks to select all the components of cell theory as outlined by Schleiden, Schwann, and Virchow. Cell theory, which is a fundamental principle in biology, includes the following components:

1. Cells are the basic unit of life.
2. All living organisms are composed of cells.
3. Cells arise spontaneously from non-living matter.
4. All cells come from pre-existing cells.

Looking at the proposed options, we can see that 'Cells arise spontaneously from non-living matter.' is not part of the cell theory. Instead, the components of the cell theory, which were contributed to by Schleiden, Schwann, and Virchow, state that:

• All living organisms are comprised of one or more cells
• The cell is the basic unit of structure and function in living organisms
• All cells arise from existing cells, through the process of cell division

Therefore, from the given options, A) Cells are the basic unit of life, B) All living organisms are composed of cells, and D) All cells come from pre-existing cells should be selected as the correct components of cell theory.
