Which of the following properties does NOT play a role in trees growing to towering heights by moving water from roots to leaves
jarptica [38.1K]

Answer:

The correct option is;

Water absorbing energy in large amounts to increase energy by a degree of temperature

Explanation:

The growth of trees to towering heights has to do with the formation of plant cell walls which are built by the aggregation Glucose molecules to form Cellulose molecules. The cellulose molecules further combines to form microfibrils by forming hydrogen bonding. The microfibrils that combine to make cell walls

Therefore, the growth of a tree is dependent on the formation of hydrogen bonds between water molecules to enable uptake of water into the plants which enable photosynthetic reaction that result in the formation of glucose

The transpiration, which is the conversion of water into vapor or gas at the leaves facilitates the uptake of more water for the formation of more glucose molecules and creation of hydrogen bonds

The hydrogen bonds between chlorophyll molecules is facilitated by forming hydrogen bond with water molecules.

  • <u>The United States: </u>The coal produced in the United States in the year 2018 was approximately 702 million tonnes. The last 12 year share of the coal produced in the US is 16.2% of the total coal produced all over the world.
  • <u>The European Union:</u> The countries that constitute the European Union togetherly produced approximately 490 million tonnes of coal in the year 2018. The last 12-year contribution of the EU to the total coal produced in the world is 9.2%.
