While we have always been made of cells, it took us a long time to see them. What innovation below was critical to the discovery of cells, showing the relationship of science and technology?
The Cell Theory is based on two observations. That all living things are made of cells and that all cells come from other cells. Which of these observations was made first?
van Leeuwenhoek called the organisms he viewed in his microscope “little animals” and described parts like legs, fins, and heads. Later studies would show that these organisms have a nucleus. What kind of cells did he likely view?
Which of the following is NOT evidence for the idea that all living things are related and share ancestry, the Theory of Universal Common Descent?
Which of the following organelles would you expect to find in a prokaryotic cell?
Which of the following pairs does NOT match an organelle with its function in cells?
While both prokaryotes and eukaryotes have DNA, in prokaryotes DNA is arranged in a circle, whereas in eukaryotes DNA is arranged in linear strands.
Because they have the same DNA and come from the same single cell, all of the cells in a human look the same.
Macrophages are cells in the human immune system whose job it is to take in and then break down potentially harmful materials like germs and cancer cells. Which organelle below would you expect to find in abundance in macrophages?
Muscle cells have special fibers that use ATP to slide across each other to allow muscle contraction and, thereby, movement. Which organelle below would you expect to find in abundance in muscle cells.
