Question

Tissue taking part in transporting organic nutrients from source or storage region is

• A. Phloem
• B. Parenchyma
• C. Vascular rays
• D. Xylem

Answer 1

The correct option is A Phloem

Sugars, which are formed by the plant during photosynthesis, are an essential component of plant nutrition. Like water, sugar (usually in the form of sucrose, though glucose is the original photosynthetic product) is carried throughout the parts of the plant by the vascular system. Phloem, the vascular tissue responsible for transporting organic nutrients around the plant body, carries dissolved sugars from the leaves (their site of production) or storage sites to other parts of the plant that require nutrients. Within the phloem, sugars travel from areas of high osmotic concentration and high water pressure, called sources, to regions of low osmotic concentration and low water pressure, called sinks.

So, the correct answer is 'Phloem'.
