Question

D. Why do we have green house in botanical
gardens?​

Answer 1

Answer:  

We need greenhouses within botanical gardens to provide plants the optimal environment for their steady growth.  

Explanation:  

Greenhouses are specific glass-enclosed spaces where the moisture, temperature, sunlight are controlled to provide the plants the right environment to grow.

Therefore, to help the young plants grow and to help nurture certain plants, greenhouses are placed within botanical gardens.
