Question

Chloroplasts play an important role in energy production in plant cells. However, some parts of a plant, like the roots, lack chloroplasts. In one to two sentences, explain the most likely pathway for root cells to obtain energy, and identify the organelles involved.

GPT-5 mini · Answer

Root cells obtain energy mainly by importing sugars (sucrose) produced in photosynthetic leaves (via the phloem) and metabolizing them rather than using chloroplasts.  
Those sugars are broken down by glycolysis and then oxidized in mitochondria (citric acid cycle and oxidative phosphorylation) to make ATP, and roots can also mobilize starch stored in amyloplasts for fuel.
