Question

What is the main function of the part labeled Xin the model?

✓O A To provide the cell with energy for its activities
OB. To store food and other materials inside the cell
C. To hold and protect the cell's DNA
XO D. To use energy from sunlight to make sugars

Answer 1

The main function of the labeled part X is to use solar energy to produce energy-storing sugars through photosynthesis, which is vital for the survival of most life on Earth.

Step-by-step explanation:

The main function of the part labeled X in the model, which refers to the site of photosynthesis, is to use energy from sunlight to make sugars. Photosynthesis is a critical biological process where plants, algae, and some bacteria convert solar energy, carbon dioxide, and water into glucose and oxygen.

The energy-storing sugars produced are essential for life because they provide the chemical energy that cells need to perform various functions. Oxygen, although a byproduct of photosynthesis, is vital for the respiration of aerobic organisms, including humans. In essence, photosynthesis fuels life on Earth and maintains atmospheric oxygen levels.
