Never visible to naked eye.Visible to light microscope during cell division
Chromosomes are not visible during the interphase stage of the cell cycle when they are in their less condensed form. Additionally, chromosomes may not be visible if the cell is not actively dividing or if they are not stained for observation under a microscope.
Chromosomes are clearly visible only when a cell is undergoing cell division, specifically during the metaphase stage of mitosis or meiosis. During this stage, chromosomes condense and become visible under a microscope.
Chromosomes are visible during prophase. Chromosomes are only visible in cells during the cell division because the DNA and protein that the chromosomes are made of are spread throughout the nucleus.
Chromosomes are visible in the cell nucleus during mitosis and meiosis.
Chromosomes, which consist of DNA and proteins, are only visible when a cell is preparing to divide. These structures condense and become visible under a microscope during cell division, allowing for the precise distribution of genetic material to daughter cells.
If chromosomes are not visible, it could mean that the cell is not undergoing cell division, as chromosomes are condensed and visible during that process. Alternatively, it could indicate that the cell is in a phase where the chromosomes are not easily distinguishable, such as during interphase. Further investigation or staining techniques may be needed to visualize the chromosomes.

The chromosomes
Chromosomes.
Chromosomes are visible during prophase. Chromosomes are only visible in cells during the cell division because the DNA and protein that the chromosomes are made of are spread throughout the nucleus.
In a normal eukaryotic cell which is not actively dividing, chromosomes are not visible. The DNA is loosely coiled, dispersed through the nucleoplasm. However, during cell division, the DNA condenses into ordered structures called chromosomes, which are visible under the microscope.
Interphase
During Prophase
Chromosomes are visible in the cell nucleus during mitosis and meiosis.
DNA is visible during mitosis (replication) when the chromosomes condense.
The phase of cell division when duplicated chromosomes first appear is called the prophase. In prophase, the chromatin condenses into visible chromosomes, and the nuclear envelope breaks down, allowing the chromosomes to be more clearly visible.
