Step-by-step solution

The plants which require only a short period of darkness to flower are known as long-day plants whereas the plants which require a short day length and the long period of darkness without any interruption by light are known as short-day plants. Day-neutral plants are those which flower in which spectrum of the amount of light it receives. The intermediate type of plants is one which does not require long
