Which of the following is needed for photosynthesis to occur?
a
sugar in the plant, which transforms into light energy
b
minerals in the soil, which transform into chemical energy
c
oxygen in the air, which transforms into electrical energy
d
energy from the Sun, which transforms into chemical energy
Question 14
d
energy from the Sun, which transforms into chemical energy
The correct answer is d) energy from the Sun, which transforms into chemical energy. Photosynthesis is the process by which plants use energy from sunlight to convert carbon dioxide and water into glucose (a type of sugar) and oxygen. This process requires sunlight as a source of energy for the plants to carry out photosynthesis.
The correct answer is option d: energy from the Sun, which transforms into chemical energy.
To determine the correct answer, we need to understand the process of photosynthesis and the requirements for it to occur. Photosynthesis is the process by which plants and some other organisms convert light energy from the Sun into chemical energy in the form of glucose (sugar). This process takes place in the chloroplasts of plant cells.
Option a, sugar in the plant transforming into light energy, is incorrect because photosynthesis does not involve the transformation of sugar into light energy. Instead, it requires light energy to produce sugar.
Option b, minerals in the soil transforming into chemical energy, is also incorrect. Although mineral nutrients obtained from the soil are necessary for plant growth, they are not directly involved in the process of photosynthesis.
Option c, oxygen in the air transforming into electrical energy, is not related to photosynthesis. Oxygen is released as a byproduct of the process, but it does not transform into electrical energy during photosynthesis.
Option d, energy from the Sun transforming into chemical energy, is the correct answer. Through the process of photosynthesis, plants capture and convert solar energy into chemical energy stored in the bonds of glucose molecules. This energy is then used for various metabolic processes within the plant.
