Question

define translocation with respect to transport in plants.why is it essential for plants?Where in plants are they synthesised 1.sugar 2. harmone

Answer 1

Hey there !

Transport of food from leaves to other parts of the plants is called Translocation. Food molecules enter the phloem cells from mesophyll cells of leaf. Once within the phloem , they can be transported upwards or downwards to all parts of the plants including roots. Food is transported in a dilute aqueous solution. 

Hope it helps you !

Answer 2

Translocation is defined as the movement of soluble materials such as minerals, proteins, hormones and sugars within the plant. Translocation occurs primarily in the vascular parts of the plant which are the xylem and phloem. These can be compared to the blood vessels which is present in animals.The xylem transports mainly water and minerals dissolved in it, these are raw materials which originally came from outside the plant and was absorbed through its roots which was then transported upwards into the xylem. The phloem transports organic materials, materials which was manufactured by the plant such as glucose, hormones and proteins.Why is it essential in plants? If there is no translocation in plants, they would not be able to obtain the nutrients such as water and minerals they need in order to manufacture food. Also if translocation didn't occur the food manufactured by the leaves would not be received by other parts of the plant.
