(c) day neutral plant

Answer 2

Answer:

Beta vulgaris is a long day plant.

Explanation:

Based on the response of the plants for day length, plants are classified into three categories.

(1) Long day plants: Plants respond to the excess critical limit of day length. E.g. Sugar beet (Beta vulgaris), Raddish (Raphanus sativus), Wheat (Triticum aestivum).

(2) Short day plants: Plants respond to the below critical limit of day length. E.g. Soybean (Glycine max), Poinsettia (Euphorbia pulcherrima).

(3) Day neutral plants: Plants do not respond to the day length. E.g. Sunflower (Helianthus annuus), Corn (Zea mays), Garden pea (Pisum sativum).
