hich 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
d
energy from the Sun, which transforms into chemical energy
The correct answer is:
d) energy from the Sun, which transforms into chemical energy
During photosynthesis, plants use sunlight as an energy source to convert carbon dioxide and water into glucose (a type of sugar) and oxygen. This process occurs in the chloroplasts of plant cells and involves the absorption of light energy, which is then converted into chemical energy. Therefore, energy from the Sun is essential for photosynthesis to occur.
To determine which of the options is needed for photosynthesis to occur, we need to understand the process of photosynthesis. Photosynthesis is the process by which plants convert light energy into chemical energy to fuel their growth. To get the answer, we will evaluate each option based on its role in photosynthesis:
a) Sugar in the plant, which transforms into light energy: This option is incorrect because sugar does not transform into light energy. Instead, plants produce sugar through photosynthesis by converting light energy into chemical energy.
b) Minerals in the soil, which transform into chemical energy: This option is incorrect because while minerals in the soil are necessary for plant growth, they are not directly involved in the photosynthesis process. Minerals mainly support other metabolic functions within the plant.
c) Oxygen in the air, which transforms into electrical energy: This option is incorrect because oxygen does not transform into electrical energy during photosynthesis. Oxygen is usually produced as a byproduct of photosynthesis.
d) Energy from the Sun, which transforms into chemical energy: This option is correct. Energy from the Sun is necessary for photosynthesis to occur. Through the process of photosynthesis, plants capture the energy from sunlight and convert it into chemical energy in the form of glucose (sugar).
Therefore, the correct answer is option d) Energy from the Sun, which transforms into chemical energy.
