Question

Assertion (A) : Unlike transport system in Xylem which can be largely explained by simple physical forces, the translocation in phloem is achieved by utilising energy. Reason (R) : The increased osmotic pressure moves the material in the phloem to tissues which have less pressure.

Answer 1

Answer:

Phloem (/ˈfloueem/, FLOH-em) is the living tissue in vascular plants that transports the soluble organic compounds made during photosynthesis and known as photosynthates, in particular the sugar sucrose, to parts of the plant where needed. This transport process is called translocation. In trees, the phloem is the innermost layer of the bark, hence the name, derived from the Ancient Greek word (phloios), meaning "bark". The term was introduced by Carl Nageli in 1858
