Verified step by step guidance
1
Understand the structure of a plant cell: A plant cell contains several organelles, each with specific functions. Key organelles include the nucleus, vacuole, mitochondria, and chloroplasts.
Identify the role of the nucleus: The nucleus is the control center of the cell and contains the cell's genetic material, DNA. It is surrounded by a nuclear envelope and contains chromatin, which is composed of DNA and proteins.
Consider the function of mitochondria and chloroplasts: Both mitochondria and chloroplasts contain their own DNA, but in much smaller amounts compared to the nucleus. Mitochondrial DNA is involved in energy production, while chloroplast DNA is involved in photosynthesis.
Evaluate the vacuole's role: The vacuole is primarily involved in storage and maintaining cell turgor pressure. It does not contain DNA.
Conclude that the nucleus contains the largest amount of DNA: Given the functions and contents of these organelles, the nucleus is the organelle where the largest amount of DNA is stored in a plant cell.
