Question:

Which one is true for dicot leaf

Options:

1. veins thickness vary
2. reticulate venation is present
3. all vascular bundles are similar in size
4. Both 1 and 2

Solution:

Dicot leaves are characterized by reticulate venation, in which the veins form a network of interconnected veins throughout the leaf blade. In dicot leaves, the veins vary in thickness, with the larger veins usually located towards the lower surface of the leaf, and the smaller veins located towards the upper surface. This variation in vein thickness helps to provide structural support to the leaf and helps to distribute nutrients and water throughout the leaf blade. Therefore, both statement 1 and 2 are true for dicot leaves. Statement 3 is incorrect, as not all vascular bundles in dicot leaves are similar in size.
