Answer: Option A.

Explanation:

A greenhouse is defined as a structure that contains walls and roof made up of transparent material like glass or plastic, under which climatic condition is maintained for the regular growth of plants inside it.

In a greenhouse, best position for pant is maintained so that exposure of sunlight should be in its optimal range.

This is so because there must be adequate amount of sunlight falling on the plant for its proper growth and development because more or less than normal amount of sunlight is not good for plants.

Hence, a plant in greenhouse should be positioned so that it's exposure to sunlight would be within its optimal range.

Why do plants have a cell wall and animals cells don’t?

algol [13]

Cell walls are supporting structures that help the plant to have a fixed shape and protect it from injury. Other than that, it helps to keep the plant turgid so that it can stay firm and upright. Because when it enters a high water potential solution, as water moves in, the water exerts turgor pressure on the cell wall and the cell wall thus exerts an opposing pressure to keep water out. Hence cell wall is needed for the plant.

On the other hand, animal cells do not need to keep the structures, as they have the skeletal system to protect the organs and cushion them against any
external injuries.
