Answer:
The correct option is;
It is used during photosynthesis to capture sunlight
Explanation:
During photosynthesis, light energy from the Sun is converted and stored in sugars as chemical energy. The Sun light energy is used in the formation of complex sugars such as glucose from the combination of water from the ground and carbon dioxide from the atmosphere while oxygen is released as the byproduct. Organisms are then able to obtain energy from the glucose as well as carbon fiber
The chemical equation for the reaction is as follows;
6CO₂ + 12H₂O + light energy → C₂H₁₂O₆ + 6O₂ + 6H₂O

Mitochondrion (mitochondria)
Answer is: D: Two molecules of potassium chloride react with one molecule of lead nitrate to form two molecules of potassium nitrate and one molecule of lead chloride.
Balanced chemical reaction: 2KCl + Pb(NO₃)₂ → 2KNO₃ + PbCl₂.
According to principle of mass conservation, number of atoms must be equal on both side of balanced chemical reaction.
KCl - potassium chloride.
Pb(NO₃)₂ - lead nitrate.
KNO₃ - potassium nitrate.
PbCl₂ - lead chloride.
