What is the name of a structure with glass or plastic walls used to cultivate plants?

• A. Greenhouse
• B. Shed
• C. Orchard
• D. Nursery

Answer: (A)

A greenhouse is specifically designed for the purpose of cultivating plants by providing an environment that is conducive to their growth. The glass or plastic walls of a greenhouse allow sunlight to enter, which helps maintain a warm temperature inside while protecting the plants from harsh weather conditions. This structure helps control humidity and can also be equipped with systems to regulate temperature and irrigation, allowing for year-round cultivation of a variety of plants.

In contrast, a shed typically serves as a storage space for tools and equipment rather than a growing environment for plants. An orchard refers to a piece of land dedicated to growing fruit-bearing trees, which is not enclosed like a greenhouse, and a nursery is a place where young plants or trees are grown for sale or for planting somewhere else, but it may not necessarily feature the controlled environment that a greenhouse does. Thus, the best term for a structure specifically constructed with glass or plastic for plant cultivation is indeed a greenhouse.
