- The surface of some parasitic flatworms and some insect tissues is a “syncytium” or living layer that contains many nuclei and cell organelles but is not partitioned by plasma membranes. These tissues consume food, respire, and produce wastes. Since the cell theory states that “all living things are composed of cells” what is the best statement to accompany this question?
A. These tissues are not living because they are not cellular
B. These tissues are obviously a bridge between nonliving and primitive living cells
C. The general concept of “life is cellular” still holds because these organisms still utilize cells sometime in their life, but this shows that plasma membrane partitions can be abandoned in some animals
D. This proves that a “vital force” beyond cell chemistry gives life to substances

- Biologists label various carbohydrates, fats and amino acids with radio-isotopes, place them in a cell culture, and allow time for cell metabolism. Then by disrupting cells in a blender and separating out various cell organelles, they find the radioactive molecules can be detected as part of various cellular compounds although visible cell structures appear unchanged. Therefore
A. these “food” molecules are used only for energy.
B. most cell components are constantly being broken down and rebuilt.
C. molecules diffuse at random through the cytoplasm and into cell organelles.
