Answer» Response of plants to periods of day/night to initiate flowering. Long day plants, short day plants and day neutral plants. Detailed Answer : Photoperiodism is the response of plants with respect to the duration of light (i.e. period of day and light). Based on the response to the duration of light, a plant is classified into three types: (i) Long day plant : Long day plants flower when they are exposed to light for a period more than the critical day length. E.g. Radish. (ii) Short day plant : Short day plants flower when they are exposed to light for a period less than the critical day length. E.g. Chrysanthemum. (iii) Day neutral plant : Day neutral plants are plants where there is no such correlation between exposure to light duration and induction of flowering response. E.g. Tomato
