Which is an organelle that stores the cell’s genetic information? The lysosome, the nucleus, the mitochondrion, or the cytoplasm?
The correct answer and explanation is:
The correct answer is the nucleus.
The nucleus is an organelle found in eukaryotic cells that stores the cell’s genetic information. It contains the DNA, which carries the instructions needed for the development, functioning, growth, and reproduction of the cell. DNA is organized into structures called chromosomes inside the nucleus. The nucleus acts as the control center of the cell by regulating gene expression and mediating the replication of DNA during the cell cycle.
Lysosomes are different organelles that contain enzymes to break down waste materials and cellular debris. They act as the cell’s digestive system, breaking down unwanted molecules into smaller parts for recycling or disposal. Lysosomes do not store genetic information.
Mitochondria are often called the “powerhouses” of the cell. They generate energy in the form of ATP (adenosine triphosphate) by converting nutrients through a process called cellular respiration. Although mitochondria have their own small amount of DNA, their main role is energy production, not storing the cell’s primary genetic material.
The cytoplasm is the jelly-like fluid that fills the cell and surrounds the organelles. It provides a medium for chemical reactions to take place and helps maintain the cell’s shape. The cytoplasm does not store genetic information but supports the organelles that perform essential functions.
In summary, among the options given, the nucleus is the organelle responsible for storing the cell’s genetic information, playing a vital role in maintaining and controlling cellular activities through the instructions encoded in DNA.
