There are 2 types of leaf venation –
1) Reticulate venation –
if the design of veins is net like on the both side of midrib is known as reticulate venation
2) Parallel venation –
if the veins are parallel to one another is called parallel venation
Transpiration –

1) Petal
2) Sepal
3) Androecium
4) Gynoecium
