During reproductive development, photosynthates are directed primarily to which destination?
ATo the roots and root tips
BTo the shoots and young leaves
CTo the seeds and the fruits
DTo the stem and the bark
Answer & Solution
Correct answer: C. To the seeds and the fruits
1. The pattern of photosynthate flow changes as a plant grows and develops.
2. Early on, photosynthates go primarily to the roots.
3. During vegetative growth they go to shoots and leaves.
4. During reproductive development they go to seeds and fruits, which is the stage the question names.
5. They are also directed to tubers for storage, which matters for crops harvested underground.
