Which of the following types of greenhouse is NOT classified on the basis of shape?

  • A.Quonset greenhouse
  • B.Plastic film greenhouse
  • C.Ridge and furrow type greenhouse
  • D.Saw tooth type greenhouse

Answer: B

The plastic film greenhouse is the type that is not classified on the basis of shape: it is named after its covering material. Quonset, ridge-and-furrow and saw-tooth houses are named for their shape and roof form.

Greenhouses are classified by shape (Quonset, ridge and furrow, saw tooth), by the covering material (glass, plastic film) and by the use. Plastic film names the covering and not the shape.
