{'nutrients': [1, 0, 3, 1], 'calcium': [2, 0, 0, 4], 'phosphorus': [1, 0, 1, 0], 'potassium': [1, 0, 0, 2], 'plants': [11, 0, 4, 4], 'manganese': [2, 0, 0, 1], 'structural component': [0, 0, 0, 1], 'cell wall': [1, 0, 0, 1]}

The correct answer is option 4, Calcium.

Calcium is an essential nutrient that plays a crucial role in the structure and strength of the cell wall in plants. The cell wall is a rigid layer located outside the cell membrane, which provides support and protection to the plant cells.

Manganese, option 1, is not a structural component of the cell wall. It is a micronutrient that is involved in various metabolic processes in plants, such as photosynthesis and enzyme activation.

Potassium, option 2, is also not a structural component of the cell wall. It is a macronutrient that is essential for regulating water utilization and osmotic balance in plants.

Phosphorus, option 3, is necessary for various physiological processes in plants, such as energy transfer, DNA synthesis, and cell division. However, it is not directly involved in the formation of the cell wall.

In summary, calcium is the nutrient that acts as a structural component of the cell wall in plants, providing strength and support to the cells.
