1. Imbibition is the phenomenon of adsorption of water or any other liquid by the solid particles of a substance without forming a solution. 

2. Imbibition is the initial step in the germination of seeds, when seed coats imbibe water ‘ followed by embryo and endosperm. 

3. Imbibition cause swelling of seeds and breaking of testa. 

4. The imbibition is dominant in the initial stage of water absorption by root hair cells. 

5. Water moves into ovules which are ripening into seeds by the process of imbibition.

Parturition : It is the act of expelling the full term young one/foetus from the mother uterus at the end of gestation period. Hormones play a major role in parturition.

It is important that baby bom when it is mature. The foetal signals that it is mature by secreting certain hormones. The hormones diffuse across the placenta into mother’s blood, where they cause the excretion of oxytocin from her pituitary oxytocin stimulate the uterine contractions. This provides force to expel the baby from the uterus causing birth.

As a result of parturition, milk is produced in the female’s breasts following the birth of a young one. The actual release of milk, requires the presence of oxytocin, to bring contraction of smooth muscles of the ducts within the mammnary glands.
