Question

The transport of soluble products of photosynthesis is called translocation, which occurs in the part of vascular tissue called
A. Xylem
B. Sclerenchyma
C. Phloem
D. Collenchyma

Answer 1

Hint: A living tissue in the vascular plants that help in the transportation of photosynthates particularly sucrose to the needed parts of the plant. This process of transportation is termed as translocation.

Complete answer:
Photosynthesis is the process of synthesis of carbohydrates in the green parts of the plant. It is divided into two phases- the light phase and the dark phase. In the light phase, energy molecules are formed with the help of sunlight whereas, in the dark phase, carbohydrates are synthesized using the energy molecules formed in the light phase. These carbohydrates are synthesized by photosynthesis and are transported to other parts (non-green) of the plant where it is needed. In higher plants, the process of transport of organic molecules from one part to another part of the plant is known as translocation. Mainly sucrose is transported through sieve tubes of the phloem whereas the water conduction takes place through the xylem.

Hence, the correct option is C-Phloem.

Note: Phloem is a type of complex tissue that helps in the process of transportation of carbohydrates such as sucrose from source (photosynthetic plant parts) to sink (non-photosynthetic plant parts). Usually, the source parts are leaves and sink parts are roots. It is a tissue that is composed of different types of cells- sieve elements, sieve plates, companion cells, parenchyma, and sclerenchyma.
