Question

problem 8 theodore schwann learned from another scientist that all plant tissue was composed of cells and that new cells formed from the nucleus of old plants. schwann looked at cells from the spinal cord of animals and discovered that they were made of also made cells, each of which had a nucleus. he also looked at tadpoles and pig embryos and found that the cells within also had a nucleus. schwann concluded that all animals are made of cells that have a nucleus. his observations, combined with observations from other scientists led to the cell theory. reasoning: if all animals are made of cells, then... complete the sentence to illustrate how reasoning was used in the scientific discoveries. for each short story, identify the claim by highlighting green. find any evidence statements and highlight in yellow.

Explanation:

The Cell Theory was developed through multiple observations. Schwann's work on plant and animal tissues, noting cell - structure and nuclei, combined with other scientists' findings about cells having nuclei, led to the generalization that all animals are made of cells. This is an example of inductive reasoning in science, where specific observations are used to form a general conclusion.

Answer:

If all animals are made of cells, then the general principle of the Cell Theory (that all living organisms are made of cells) is further supported by the specific case of animals.
Claim: All animals are made of cells.
Evidence: Schwann's observations of plant and animal tissues (spinal cord of animals, plant tissue), discovery of nuclei in cells, and observations of cells in tadpoles and pig embryos; other scientists' findings that cells have nuclei.
