Step-by-step explanation:

Solution:-

The experimental unit is the physical entity which can be assigned, at random, to a treatment. ( The treatment in our scenario is the effect of two types of fertilizers Type A and Type B on the plants )

- Commonly it is an individual animal - plant. The experimental unit is also the unit of statistical analysis. ( statistical analysis is done on the plants divided into two groups: Group 1 and Group 2 )

- However, any two experimental units must be capable of receiving different treatments. ( Group 1 - Type A fertilizer ) & ( Group 2 - Type B fertilizer ).

The experimental unit are the two groups ( Group 1 and Group 2 ) each consists of 20 plants.
