The correct answer is Phloem
Explanation:
Phloem is a transport tissue of vascular plants. It is used for transport of food and nutrients, so sugar is definitively brought by phloem.Other choices cannot be right because collenchyma and parenchyma are ground tissues, while xylem is the carrier tissue similar to phloem but worked for a conveyor of water and minerals.

Answer:
The mentioned case is an illustration of the missense mutation. A missense mutation is a kind of nonsynonymous substitution, that is, it is a mutation in which a variation in a solitary nucleotide leads to the formation of a codon, which encrypts for a distinct kind of amino acid.
When a missense mutation takes place within a DNA, a modification in one of the RNA codon sequences results at the time of transcription. This change in codon will ultimately result in the formation of a different amino acid, which gets presented within a protein at the time of translation. Like in the given case, a change in codon resulted in the substitution of the amino acid tyrosine with an amino acid cysteine.
