Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which statement about phloem is true?
A
it carries nutrients to growing regions of the plant
B
it carries nitrate ions from the leaves to the roots
C
it carries sugars from the roots to the leaves
D
it carries water from the roots to the leaves
Explanation: 

Detailed explanation-1: -The correct answer is Phloem transports photosynthetic products. Phloem is a living tissue in vascular plants that conducts the soluble organic compounds synthesized downwards from the leaves during photosynthesis. Hence option 2 is correct.

Detailed explanation-2: -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.

Detailed explanation-3: -Which statement describes the role of phloem within a plant? It transports food to all the parts of the plant both upwards and downwards.

Detailed explanation-4: -They are bordered by companion cells that carry out the cellular functions of a sieve-tube element. Phloem tubes can carry sugars and amino acids in a variety of directions; depending on where the source and the sinks are located (sometimes roots can be sources or sinks).

Detailed explanation-5: -Final answer: Phloem transports food from the leaf to other parts of the plant.
