Question

however, schwann and schleiden misunderstood how cells grow. schleiden believed that cells were \seeded\ by the nucleus and grew from there. similarly, schwann claimed that animal cells \crystalized\ from the material between other cells. eventually, other scientists began to uncover the truth. another piece of the cell theory puzzle was identified by rudolf virchow in 1855, who stated that all cells are generated by existing cells when they divide in two. there has been some evidence that suggests virchow plagiarized his work on cell division from his former colleague robert remak. the third premise of the cell theory states that cells come from preexisting cells by cell division. describe how the work of virchow/remak supports this premise. state the original/modern cell theory

Explanation:

1. Virchow (and potentially Remak) stated that all cells are generated by existing cells when they divide in two, which directly supports the premise that cells come from pre - existing cells by cell division.
2. The original cell theory has three main points: all living organisms are made up of cells; the cell is the basic unit of life; cells come from pre - existing cells. The modern cell theory builds on this and includes concepts about the cell's biochemical and molecular functions.

Answer:

1. Virchow (and possibly Remak) proposed that cells originate from the division of pre - existing cells, thus supporting the premise.
2. Original cell theory: All living things are composed of cells; the cell is the basic unit of life; cells come from pre - existing cells. Modern cell theory: Builds on the original and includes more about cell biochemistry and molecular aspects.
