Tonicity is a comparative term that has no units. It is frequently used when describing what happens in the cell volume at equilibrium. Tonicity always compares a solution and a cell, and it is used to describe only a solution. Tonicity is related to its osmolarity. There are three terms, hypotonic, isotonic, and hypertonic that used to compare the extracellular fluid around.

AURORKA [14]

<u>Answer</u>:

16 - light

17 - $H_{2}O$

18 - $CO_{2}$

19 - $O_{2}$

20 - sugar

The image describes the process of photosynthesis and the production of sugar through the Calvin cycle. Light is the energy source that drives this process through which, together with water molecules, chemical energy known as ATP is produced. This and NADPH, which is also produced during photosynthesis, are used to drive the Calvi Cycle. Here, by using atmospheric $CO_{2}$ , sugars are produced. These are vital to the survival and growth of the plant. Oxygen is also released into the atmosphere as a result of photosynthesis.
