What is the role macromolecules play in relation to life on earth

There are four types of macromolecule :

1)Carbohydrate

2) Protein

3) Lipids

4) Nucleic acids

Carbohydrate: They store energy, provide fuel and they are main buliding structurein body, main source of energy ,Structure of plant cell wall.

Nucleic Acids: DNA and RNA are nucleic acid , they store and transfer information .

Lipids: They store fats and energy . They are insulator.

Protein: They generally provide structural support , transport, enzymes , movements and defense.

So, these are the macromolecule which play important role in our life.

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.
