*The two cellular structure that work together to synthesize, modify and transport macromolecules within the cell is endoplasmic reticulum and golgi apparatus.
*The endoplasmic reticulum is a synthesis and transport organelle that branches into the cytoplasm in the plant and the animal cell.

That would be temperature. (:
