Answer:
A. Transport of materials in xylem
Xylem tissue helps in the transport of water and minerals
Water is transported upwards from roots to aerial parts of plants
Transport in xylem requires physical forces such as transpiration pull.
B. Transport of materials in phloem
Phloem tissue helps in the transport of food.
Transport of food in phloem requires energy in the form of ATP.
 Food is transported in both upward and downward directions.

Answer:
Framshift mutation
Explanation:
The frame shift mutation is also known as reading frame shift or framing error mutation, during which an insertion or deletion occurs at a single position but it effects the sequence of whole gene in such a way that complete sequence is disturbed.
If we look at the sequence given in example:
Wild sequence: the big red fly had one eye
Mutant:               the fbi gre dfl yha don eey 
An insertion mutation occured at the start of sequence big, where f got inserted. We know that a 3 set of nucleotides called codon is transcribed and translated into single amino acid of protein. So when f got added it disturbed the frame and all the sequences of next codons got altered. 
- big  changed to fbi 
- red changed to gre 
- fly changed to dfl 
- had changed to yha 
In short the ehole protein will have wrong sequence of amino acid and it is worst type of mutation that badly effects an organism.
Hope it help!
