Hint: The arrangement of veins and the veinlets in the lamina of leaf is termed as venation. When the veinlets form a network, the venation is termed as reticulate . Dicots have reticulate venation whereas monocots have parallel venation.
Complete answer:
First of all let’s see what is venation, it is the arrangement of veins and the veinlets in the lamina of leaves .
The venation is said to be reticulate, when the arrangement of the veins and veinlets form a network, as shown in the following picture.
As shown in the diagram, the veins are veinlets arranged in reticulate venation.
Now let us take each leaflet as given in the question one by one
>Wheat
As it is clear from the picture wheat leaf has parallel venation.
> Tulsi
As we can see the venation seen in tulsi leaf is reticulate.
> Maize
You can see since maize is an example of monocot, it also has parallel venation.
> Grass
It is also a monocot, the venation seen is parallel.
> Coriander (Dhania)
It is an example of dicot, hence the venation seen is reticulate.
> China Rose
It belongs to the dicotyledons category, and it also has reticulate venation.
Additional information:
There are some exceptions as follows:-
Exceptions-Dicots which show parallel venation- Calophyllum, Corymbium.
Monocots which show reticulate venation- Alocasia, Colocasia, Smilax.
Hence, we can conclude that Tulsi, Coriander and China rose have leaves with reticulate venation.
Note: Dicotyledonous plants have reticulate venation whereas the monocotyledonous plants have parallel venation but exceptions are always there in biology.
The pictures given can help you relate to the answer.
