Question:

As microscope technology improved over time, the magnification became advanced enough to discover cells in the 17th century. This discovery is largely attributed to Robert Hooke and began the scientific study of cells, also known as cell biology. Over a century later, the debate continued among scientists about how cells began. Most of these debates involved the nature of cell reproduction and the idea of cells as a fundamental unit of life. Cell theory was eventually formulated in 1839.
The three tenets to the cell theory are as described below:
1. All living organisms are composed of one or more cells.
2. The cell is the basic unit of structure and organization in organisms.
3. Cells arise from pre-existing cells.
Anton van Leeuwenhoek is a scientist who saw cells soon after Hooke did. He made use of a microscope containing improved lenses that could magnify objects almost 30ox. Under these microscopes, Leeuwenhoek found moving objects that he named “animalcules,” which included protozoa and other unicellular organisms, like bacteria. He was also able to observe red blood cells and sperm cells. Leeuwenhoek's research can be used to support which of the tenets of cell theory?
A) Some cells emerge spontaneously.
B) Cells arise from pre-existing cells.
C) All living organisms are composed of one or more cells.
D) The cell is the basic unit of structure and organization in organisms.

THe answer is D

Explanation:

It is D because he talked about that topic during the whole paragraph

1.All living things are made up of one or more cells. 2.A cell is the most basic structure of organisms. 3.All living cells come from pre-existing cells.

1!

Explanation:

Cells are the basic unit of life.

A.) all cells come from another pre-existing cell

Answer B) Cell division demonstrates that cells come from pre existing cells.

B) Cells arise from pre-existing cells.

some cell emerge spontaneously

The correct answer will be option-B.

Explanation:

Cell division is the process which divides a parent cell to daughter cells through sequential steps as a part of the cell cycle. The cell division takes place in two phases: Karyokinesis- the division of nuclear material and the cytokinesis- the division of the cytoplasm.

The cell division proves one aspect of the cell theory proposed by Rudolf Virchow that is cells arises from the pre-existing cells as the pre-existing cell divides to form the daughter cells through cell division.

Thus, Option-B is the correct answer.

The three statements from the cell theory are :

All living things are made up of cells.Cells are the smallest unit ant the building blocks of life.All cells arise from preexisting cells.

The cell theory is significant because it explains that all living things are made up of a cell or many cells. Hence, this theory differentiates living things from  non- living things. This theory lays the foundation of biology.
