Although nitrogen gas makes up 78% of the atmosphere, we can't use it because _____. nitrogen gas is explosive we must absorb it
Sedaia [141]

Nitrogen, even though makes for about 78% of our atmosphere, and is by far the most abundant gas in it, we can not use it because it can not be taken out of the atmosphere as it is. If we take nitrogen in the form as it is in the atmosphere it is useless for both humans and plants. It has to go through a process of ''fixation'' first before we can actually use it in our food.

Plant leaves produce starch as an energy molecule through the process of photosynthesis. Starch is a polysaccharide. Which monos
Sonja [21]

Monosaccharide molecule is produced and stored as energy for future use is Glucose.

Unlike people, plants must produce their own energy through photosynthesis in order to meet their needs for fuel. Plants produce and store starch in their leaves for short-term needs.

A polysaccharide, such as starch, is created when a series of glucose molecules are bonded together to form a longer molecule.

In starch, there are two varieties of polysaccharides:

  • Amylose – a linear chain of glucose
  • Amylopectin – a highly branched chain of glucose

Depending on the plant, starch is made up of between 20-25% amylose and 75-80% amylopectin.
