Answer:

1.

1) All living organisms are composed of one or more cells.

2)The cell is the basic unit of structure and organisation in organisms.

3) Cells arise from pre-existing cells.

2. The first observations of bacteria and protozoa. His extensive research on the growth of small animals such as fleas, mussels, and eels helped disprove the theory of spontaneous generation of life.

3. law of elasticity (Hooke's law), for his first use of the word cell in the sense of a basic unit of organisms (describing the microscopic cavities in cork), and for his studies of microscopic fossils, which made him an early proponent of a theory 

4. His discovery of the nucleus and its role helped to put together the cell theory, which states that all living organisms are composed of cells, and cells come from pre-existing cells. 

5. He published his findings and called the process he saw “binary fission”. He concluded that all plant tissues are composed of cells and that an embryonic plant arose from a single cell. He declared that the cell is the basic building block of all plant matter.

6. Schwann demonstrated the same fact for animal tissues, and in 1839 concluded that all tissues are made up of cells: this laid the foundations for the cell theory.

7. that the sperm and egg were composed of cells and that humans are formed of cells from beginning to end.

8. In 1855, he further developed his ideas by publishing his famous aphorism omnis cellula e cellula which became a part of the foundation for cell theory. Virchow's theory stated that just as animals are unable to arise without previously existing animals, cells are unable to arise without previously existing cells.

9. Pasteur's experiment showed that microbes cannot arise from nonliving materials under the conditions that existed on Earth during his lifetime. The experiment had to do with Pasteur adding nutrient broth to flasks, bent the necks of the flasks into S shapes, and then boiled the broth to kill any existing microbes.

10. All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing.
