Aplant is noticed to have curled leaves and stunted growth. which nutrient is it most likely missing?
a. magnesium
b. potassium
c. calcium
d. phosphorous

The right answer is Calcium.

Calcium (Ca) is one of three secondary nutrients required by plants for healthy growth - the other two nutrients being magnesium (Mg) and sulfur (S).

Role of calcium

Calcium, in the form of calcium pectinate, is responsible for the cohesion of the cell walls of plants. When there is calcium deficiency, new tissues, such as root tips, young leaves and shoot tips, are often deformed due to poor cell wall formation. Calcium is also used as an enzymatic cofactor and for the transmission of signals that coordinate certain cellular activities.

the generally accepted parts of modern cell theory include: all known living things are made up of one or more cells. all living cells arise from pre-existing cells by division. the cell is the fundamental unit of structure and function in all living organisms.
