Answer:
You have to use chargaff's rule:
A+G=T+C
A=T
C=G=32%
A+T=100-2x32=36%
A=18%
A=18% T=18%
One is through turgidity. this occurs before ground tissue ( collenchyma and sclerenchyma cells) become well developed to give structural support to the plant as it grows bigger. The xylem tissue (composed of rigid tissue) of the young plant render this support and also maintaining osmotic turgidity of the surrounding plant cells.
That would be coal because you can cook with coal, build things out of coal, and use it for energy
