both green-stemmed plants and purple-stemmed plants produce a pigment that can be used for photosynthesis.
only green-stemmed plants produce a pigment that can be used in photosynthesis.
only purple-stemmed plants produce a pigment that can be used for photosynthesis
neither green-stemmed plants nor purple-stemmed plants produce a pigment that can be used for photosynthesis.
