Bulbil is a small bulblike organ of vegetative reproduction growing in leaf axils or on flower stalks of plants such as the onion and tiger lily. It is a reproductive organ that takes part in vegetative reproduction. The bulbils drop from the parent plant on to the ground, give out adventitious roots and develop into new plants.

Coconut water, the clear liquid inside young green coconuts (fruits of the coconut palm), is liquid endosperm. In early development, it serves as a suspension for the endosperm of the coconut during their nuclear phase of development. It contains sugars, vitamins, minerals, proteins, free amino acids and growth promoting factors.

Resin in the most specific use of the term is a hydrocarbon secretion of many plants, particularly coniferous trees. It is distinct from other liquid compounds found inside plants or exuded by plants, such as sap, latex, or mucilage.
