Nucleus
B
Chloroplast
C
Mitochondrion
D
Golgi apparatus
Verified step by step guidance1
Step 1: Understand the function of DNA in the cell. DNA contains the genetic instructions necessary for the development, functioning, and reproduction of living organisms. It acts as the blueprint for cellular activities.
Step 2: Identify the organelle responsible for storing DNA. In eukaryotic cells, DNA is stored in a membrane-bound structure called the nucleus.
Step 3: Recognize the role of the nucleus as the control center of the cell. The nucleus regulates gene expression and coordinates cellular activities such as growth, metabolism, and reproduction.
Step 4: Compare the functions of the other organelles listed: Chloroplasts are involved in photosynthesis, mitochondria generate energy through cellular respiration, and the Golgi apparatus processes and packages proteins and lipids.
Step 5: Conclude that the correct answer is 'Nucleus,' as it is the organelle that stores DNA and acts as the control center for the cell.
