image #1 cell theory the cell is the smallest unit of life. all living things are made of one or more cells. all new cells come from preexisting cells. image #2 schleiden schwann cell theory virchow title: video notes wrap - up 1. copy the images. use the back of video notes page if you have room. 2. write a detailed description for each image in your own words. helpful hint image 1: “the cell theory states i.y.o.w. this is important because ”. helpful hint image 2: “schleiden, schwann, & virchow each contributed list what each scientist contributed to the cell theory. 1. write a summary (3 - 5 sentences) that describes how continuous investigations and new scientific information influenced the development of the cell theory.”

Explanation:

The cell theory states that the cell is the smallest unit of life, all living things are made of one or more cells, and all new cells come from pre - existing cells. Schleiden, Schwann, and Virchow contributed to this theory. Schleiden proposed that plants are made of cells, Schwann proposed that animals are made of cells, and Virchow stated that all cells come from pre - existing cells. Continuous investigations and new scientific information led to the refinement and acceptance of the cell theory. Scientists built on each other's work, with new observations and experiments providing evidence and clarifying details.

Answer:

1. Image 1: The cell theory states that the cell is the fundamental unit of life, meaning it is the smallest entity that can be considered alive. All living organisms are composed of one or more cells, and new cells arise from pre - existing cells. This is important because it provides a basic understanding of the structure and reproduction of living things, forming the foundation of modern biology.
2. Image 2: Schleiden contributed the idea that plants are composed of cells. Schwann proposed that animals are also made up of cells. Virchow added the crucial concept that all cells come from pre - existing cells.

Summary: Continuous scientific investigations, such as the work of Schleiden, Schwann, and Virchow, gradually built up the cell theory. New information from microscopy and other research methods helped to clarify and expand the understanding of cells as the basic units of life. Each scientist's contribution was a step in the development of this important biological theory.
