Explanation:
The synthesis of carbohydrate food materials, mainly through the process of photosynthesis, occurs in green cells of the plant. The non-green cells are therefore dependent on photosynthetic cells for their carbohydrate supply. The organic carbon mainly from the leaves is transported to the non- green parts where it is needed for respiration and biosynthesis. The transport of organic solutes from one place to another in higher plants is known as translocation. Carbohydrates are translocated from leaves to roots and storage organs along the phloem in the form of sucrose. They are translocated through living sieve elements of phloem.
The transport of water and mineral elements absorbed by roots from the soil takes place through the xylem.
Sclerenchyma is made up of dead cells which are highly thickened due to lignification and provide mechanical strength to the plant.
Collenchyma is a plant tissue which is present in hypodermis of dicot stems and petiole of the leaf. It provides tensile strength to the plant part.
