Question

What is the role of calcium in plant growth?

Answer 1

Hint: Elements are very necessary for the plant growth calcium plays an important role in plant growth. All living species, including plants, require calcium; most soils have enough calcium, but not in a form that plants can use. Milk is a good source of calcium, not only for humans, but for plants as well.

Complete solution:-
Calcium (Ca) is essential for the formation of plant tissues and for the improvement of plant growth. Calcium is responsible for keeping plant cell walls together. It's also important for activating enzymes and sending signals that coordinate cellular functions.

Calcium is essential for normal root system growth. Calcium also boosts the feed value of forage crops to cattle and increases their resistance to outside attack. Root growth is stunted and the root tips perish as a result of calcium shortage.

The crop becomes disease-prone due to a lack of calcium. Blossom end rot in tomatoes, tip burn in cabbage, and black heart in celery are examples of these illnesses. Because calcium is immobile in plants, Deficiency symptoms emerge on younger plants as calcium delivery ceases. The edges of new leaves are curled, and the growing tip may die.

Calcium is an essential macronutrient for plant growth. These macronutrients are important components that plants require in quantities greater than 1mg/g dry matter. They are employed as a calcium pectinate in the cell wall to create the middle lamella for lipid processing. They also play a role in the cell's expansion and division.

Note:-
Calcium deficiency can be caused by calcium competing with magnesium and potassium intake, resulting in deficiency. Shells (egg, clam, or oyster), lime, gypsum, wood ash, bone meal, and calcium nitrate are all calcium-rich fertilisers. Some of these will change the pH of your soil, so bear that in mind when applying them and get a soil test first.
