1. The problem asks which statements Schwann and Schleiden would make regarding cell theory. 2. Schwann and Schleiden are known for their contributions to cell theory: Schleiden stated that all plants are made of cells, and Schwann stated that all animals are made of cells. 3. Statement I: "Plant cells are formed from fertile soil" is incorrect and not related to Schleiden's idea. 4. Statement II: "Animal cells must function properly for an organism to be healthy" is a general biological fact but not a direct statement from Schwann or Schleiden. 5. Statement III: "Cells make up the petals, stem, and leaves of a lily plant" aligns with Schleiden's statement about plants being made of cells. 6. Statement IV: "Bacteria are produced from other living bacteria" relates to cell reproduction but is not directly from Schwann or Schleiden. 7. Therefore, Schwann would make Statement II (about animal cells) and Schleiden would make Statement III (about plant cells). Final answer: Schwann would make Statement II and Schleiden would make Statement III.
