Solution:
The group of plants requiring less time of exposure to light are known as short-day plants whereas those which require longer duration are known as long-day plants, these plants can grow simultaneously in the same place. Vernalisation is a phenomenon which promotes flowering by preventing early reproductive development and giving the plants time to reach maturity.

The plant growth and development depends on many factors like temperature, light and water.
