Solution
Since Chrysanthemum is a short-day plant, its flower mainly develop during night and hence they require long nights of 11 to 12 hours. Blackout system is sometimes used to induce flowering.Flowering can be delayed by regulating both light and temperature. this is done by exposing plants for a short period of time to light (can be artificial) and to some source of heat that produces 85° F or higher temperature.
Thus if flowers are required in month of may, flowering can be delayed by exposing Chrysanthemums plant to light and heat source during night time
Option D is correct
Yes plant cells do have mitochondira
So the simple answer would be evaporation is slow and can only occur through the surface of a liquid and it cools it down, while boiling is fast and produces bubbles ( evaporation does not ) and it occurs throughout the liquid and doesn’t cool it down. A similarity between the two would be water vapor is given off
Both the processes of evaporation and boiling result in a change from liquid to vapor.
