Explanation:
The most prominent organelle that contains genetic material and is visible in most eukaryotic cells is the Nucleus.
<h3>What is Nucleus?</h3>
- The nucleus is a double membraned organelle found in all eukaryotic cells.
- It is the largest organelle, which functions as the control center of cellular activities and is the storehouse of the cell's DNA.
- The nucleus is dark, round, and surrounded by a nuclear membrane.
- Within the nucleus, there are tiny spherical bodies called the nucleolus. It also carries an essential structure called chromosomes.
- So the nucleus is the organelle that is visible and present in all eukaryotic cells.
