Question

What is the percentage of absorbed water used in photosynthesis?
A. One percent
B. Five percent
C. Ten percent
D. Ninety percent

Answer 1

Hint: The absorption of the water in the plants takes place through roots. The water is drawn up by the root hair cells through the process of osmosis. The process of photosynthesis is carried out only in the presence of water, which is absorbed by the roots in the plants.

Complete answer: The water is the most limiting abiotic factor to plant growth and productivity, and a principal determinant of the vegetation distributions worldwide. The water's importance to the plants stems from its central role in the growth and the photosynthesis and the distribution of organic and inorganic molecules. Despite this dependence, the plants retain less percent of the water absorbed by roots for cell expansion and plant growth. The remainder passes through plants directly into the atmosphere, a process referred to as transpiration. The amount of water lost through transpiration can be incredibly high. Water is an essential component of the process of photosynthesis. It is a limiting factor as well. One percent of absorbed water is used during the process of photosynthesis.

Therefore, the correct answer is option A.

Additional information:
While the plants take in carbon dioxide through the tiny pores located on their leaves, stems, and flowers, they need specialized structures to gather the water and move it up through their stems. Most of the plants use roots to pull water from the earth. The plants with enough water and carbon dioxide harness the power of photons gathered from the sunlight to complete the process of photosynthesis. The six molecules of carbon dioxide and six molecules of water on the left side of the photosynthesis equation break apart and reconfigure into glucose and six molecules of oxygen.

Note: The water helps in the cell enlargement due to the turgor pressure and the cell division which ultimately increase the growth of the plant. Water is essential for the germination of seeds, growth of plant roots, and nutrition and multiplication of the soil organism. The water is essential in the hydraulic process which takes place in the plant.
