Plant grows better in net house because

Solution
The correct options are
A It provides moderate temperature.
B It protects the plant from insects.
Some of the advantages of growing plants in a net (or greenhouse) house are as follows - - Temperature Control - Outdoor temperature swings range widely between day and night. Plants subjected to extreme cold and heat across a 24-hour period do not grow as well as greenhouse plants and stressed plants become stunted over time. The enclosed indoor space greenhouses provide is typically temperature-controlled with heaters and air ventilation for specific plant species, such as food crops.
- Carbon Dioxide Factor - Controlling indoor air movement provides the greenhouse plants with a constant supply of carbon dioxide, which they need for sugar production. Although outdoor plants have sufficient carbon dioxide levels, strategically placed horizontal fans throughout a greenhouse allows air to press closer to the foliage for peak photosynthesis action. The concentrated carbon dioxide results in larger leaves, stronger plant stems and possible early flowering and fruiting.
- Reduced Pest and Disease Exposure - Plants in greenhouses grow in containers with specifically chosen soil. Unlike an outdoor garden, your greenhouse container soil does not have the potential of harbouring harmful diseases and pests. As a result, your greenhouse is practically sterile to fungi, bacteria and pests, such as borers. Without stressful pathogens and pests, the plants concentrate on healthy growth rather than repair and defence.
- Considering Humidity - Plant foliage transpiration relies on a constant supply of moisture from both the roots and surrounding atmosphere for peak growth. Dry, outdoor conditions force plants to rely solely on soil moisture, which can cause water stress, especially if the roots are in drought conditions. Stunted growth and reduced resistance to pests and diseases occur when dry conditions stay constant for an outdoor plant. But greenhouses with humidity controls keep the air moist for peak plant growth. Reducing water stress by watering the roots and providing a humid environment allows each plant to concentrate its energy on fruiting and flowering.
So the correct option is ' Both A & B ' .
A It provides moderate temperature.
B It protects the plant from insects.
