• B) this proves some vital force is involved beyond normal cell structures in order to give life to living organisms.
• C) these tissues are obviously a bridge between nonliving and primitive living cells.
• D) the general concept of life-is-cellular still holds since sometime in their life these organisms still utilize cells, but this shows cell membranes can be abandoned.
