Tap roots of carrot, turnip and adventitious root of sweet potato, get swollen and store food.
Pneumatophores conducts water, minerals & photosynthesis
Pneumatophore is found in the plants that grow in sandy soil.

Imbricate aestivation is found in papilionaceous family.
Generally sepals are green, leaf like and protect the flowers in the bud stage.
In cymose type of inflorescence, the main axis terminates in a flower, hence is limitless in growth.
In axile placentation ovary is one chambered but it becomes two cambered due to formation of the false septum.
Bulb of Allium cepa is a modified stem.
Cloves of Allium sativum are fleshy scale leaves.
Corm of Colocasia is a modified root.
Tendril in Vitis vinifera is a modified axillary bud.
