Concept:Arrow II indicates the transport of food manufactured by the leaf to other plant parts.
During photosynthesis, the leaf produces glucose, which is a photosynthate.
Explanation:In the given diagram, the leaf is the site of photosynthesis.
The glucose made here is converted into sucrose and other organic substances.
Arrow II shows these organic food materials being transported away from the leaf.
This movement of manufactured food is called translocation.
Translocation occurs through the phloem tissue.
Arrow II does not represent the release of oxygen, which mainly diffuses out through stomata.
It is also not the intake of carbon
(IV) oxide, which moves into the leaf from the air.
Further, it is not the movement of raw mineral nutrients, which are absorbed by roots and carried upward through the xylem.
Therefore, arrow II specifically shows the movement of photosynthates.
Answer:C. movement of photosynthates
