Answer:
Some flowering plants have leaves that lack venation even though the stems and roots have vascular bundles.
Explanation:
Venation refers to the arrangement of the veins in the leaf of a plant which are involved in the transport of material in the plants.
The xylem present in leaves transports water to the leaf whereas phloem transports sugar from the leaves to different parts of the plants. In angiosperms, no plants are known whose leaves lack the veins but stem and root possess the vascular bundles.
Monocot is characterised by their parallel veins whereas dicots possess reticulate veins. Also, the compound leaves possess one of the three types of venation that are palmate, pinnate and dichotomous.
Since no angiosperm posses, veinless leaves, therefore, is the correct answer.
