You decide to plant potatoes in your garden. You watch the above-ground development of each plant and decide to categorize the growth into four main stages:
1) the initial development of the stem and leaves (shoot)
2) the development of flowers and general growth of the shoot
3) a vegetative period where not much growth seems to be happening
"4) the harvest of your potato crop (digging up the tubers formed near the base of the stem)
In terms of carbohydrate distribution, during what stage is the majority of phloem flow from shoot to root?"

Question

Quizplus · Accepted Answer

During stage 3, the plant enters a vegetative phase where it focuses on root growth and storage of carbohydrates in the form of starch in the tubers, which are the desired product when harvesting potatoes. This means that the majority of phloem flow will be from shoot to root during stage 3, as the plant is storing nutrients in preparation for the harvest.
