Hint: The veins of a leaf represent the vascular structure of the organ that extends into the leaf via the petiole and provides the transportation of water and nutrients between the leaf and the stem.
Complete answer: The veins play an important role in the maintenance of the status of the water in the leaf and the capacity of photosynthesis.
Veins in leaves are made up of two major tissues – xylem and phloem.
It helps to provide mechanical support to the leaf.
It also helps in the transportation of both water and minerals, where water is transported by xylem tissue and food and organic nutrients are transported by phloem tissue to the other parts of the plant body.
Thus, the correct answer is option D. All of the above.
Note: There are two types of veins seen in the angiosperms – parallel and reticulate or net-like structure.
In general, parallel venation is typically seen in monocot plants, for example, banana trees, whereas reticulate veins are more typically seen in the case of eudicots and magnoliids or dicots, for example, Rose, China rose, etc.
