Question 8

As they flow over rotten logs as a fluid sheet,slime molds appear to lack any partitioning into individual cells; however,slime molds do become cellular when they change form to produce spores.The surface of some parasitic flatworms and some insect tissues are a "syncytium" or layer of living material that contains many nuclei and cell organelles but lacks partitioning by cell membranes.These tissues consume food and produce wastes.In light of the cell theory that "all living things are composed of cells," then

Accepted Answer

A) these tissues are not living because they are not cellular. 
B) these tissues are obviously a bridge between nonliving and primitive living cells.

D) this proves that a "vital force" beyond cell chemistry can give life to substances. 
E) All of the choices are true.
