- Ray, a struggling apprentice of a famous scientist, wanted your help as to distinguish a particular case. He was able to find a cell that made him curious, and wanted to know more about the said cell. You have the task to identify the cell. What part/parts of the cell would you use as reference to classify it under a particular kingdom, and why?Do you consider it a reasonable conjecture that cells could have arisen as bare cytoplasm without a cell membrane?Fill in the blanks, using the choices provided, to correctly identify the contributions to the Cell Theory. G2 In the late 1600s, a Dutch tailor who crafted lenses, used his primitive microscope to view pond water, the plaque In 1665, from his own oral cavity, as well as his own sperm. He referred to all of the organisms he viewed as coined the term to describe the cork tissue he was observing through a lens.
