23. Etiolation in plants is due to
a) Total darkness
b) Full sunlight
c) Vitamin deficiency
d) Virus disease
Etiolation is a condition caused by the growth of plants in the absence of light. An etiolated plant cannot complete
synthesis of chlorophyll when grown in darkness, so that the leaf is yellowish or whitish, due only to the presence
of yellow carotenoids.In etiolated plants, there are no normal chloroplasts, because in the constant darkness the
typical membrane and protein portions of the organelle cannot be made. So Etiolation in platns is due to the absence
of a growth-inhibiting secretion formed by the chloroplasts In the light.
