The surface area will be:
S.A. = 6l²
S.A = 6(100 x 10⁻⁶)²

Volume = l³
Volume = (100 x 10⁻⁶)³

Surface area to volume ratio:
[6(100 x 10⁻⁶)²] / (100 x 10⁻⁶)³
S.A : Vol = 6 x 10⁴

Answer:

plants take in carbon dioxide (CO2) and water (H2O) from the air and soil.

Explanation:

During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
