Which one(s) contribute the most to the mass of a plant? i. soil ii. carbon iii. water a) i only b) ii only c) i and iii only d) ii and iii only

 D) II and III only

The mass of the plant is primarily carbon. The carbon comes from the carbon dioxide absorbed by the plant from the atmosphere. The process of photosynthesis utilizes the light energy from the sun to be converted into chemical energy in the form of carbohydrates, which is a source of carbon. The water is absorbed by the plants through the roots. The water makes up 75% of the entire plant structure. It is a necessary ingredient of each plant cell, it is a solvent which allows the dissolution of plant nutrients, hormones and toxins. Water keeps the plants in the erect state, in the absence of water wilting can occur and plant may die.
