The correct answer is option (A) Variation in the strawberry plants.

When the effect of fertilizer on the growth of two strawberry plants is tested, unavoidable source of experimental error is the variation in the strawberry plants. Variation refers to the deviation or differences from the normal plant which can be due to genetic variation. It is due to change in the DNA sequence. If any one of the two plants being tested show variation, the rate of metabolism differs and changes the growth pattern of the plant. The rate of absorption of water and nutrients is effected which brings change in the growth of the plant and causes an error in the experiment and the result.

mart [117]

Answer:

B. Mitochondria

Explanation:

  • Mitochondria are known as the power house of the cell. They are the sites of cellular respiration that breaks down glucose into energy molecules such as ATP and energy storage molecules such as NADH and FADH2.
  • In this scenario, since the cell's energy levels fall and metabolism ceases, the organelle most likely affected is the mitochondria.
  • If mitochondria are affected, glucose will not be metabolized to ATP and the cell will not have sufficient energy for cellular functions.
