How does the cell obtain energy for the process?
a
The cell makes the needed energy in mitochondria.
b
The cell makes the needed energy from soil nutrients.
c
The cell obtains the needed energy from sunlight.
d
The cell obtains the needed energy from food.
c
The cell obtains the needed energy from sunlight.
c
The cell obtains the needed energy from sunlight.
To understand how a plant cell obtains energy for the process of making glucose from carbon dioxide and water, we can look at the process of photosynthesis. Photosynthesis is the biological process by which plants convert sunlight into energy in the form of glucose.
During photosynthesis, plants use a molecule called chlorophyll found in chloroplasts (a specialized organelle found in plant cells) to absorb sunlight energy. This energy is then used to power a series of chemical reactions that convert carbon dioxide and water into glucose, releasing oxygen as a byproduct.
The sunlight is captured by the chlorophyll in the plant's leaves and other green structures, such as stems and young branches. This captured sunlight provides the necessary energy to drive the chemical reactions that synthesize glucose molecules. The glucose produced by the plant cells serves as a source of energy to fuel various cellular processes within the plant.
Therefore, the correct answer is c. The cell obtains the needed energy from sunlight.
