they are produced in the nucleus of cells. a human has 23pairs of chromosomes.

Allium cepa, also known as onion, has a total of 16 chromosomes. These chromosomes exist as eight pairs, with each pair consisting of two homologous chromosomes.
Chromosomes are usually found in pairs in most organisms, with one chromosome inherited from each parent. Humans have 23 pairs of chromosomes, for a total of 46 chromosomes. Exceptions do exist, such as sex chromosomes in some species.
There are no homologous chromosomes in a haploid cell, as a haploid cell has only one set of chromosomes. One member of each pair of homologous chromosomes comes from one set, and the other member comes from the second set, so homologous chromosomes only exist in diploid cells.
Chromosomes play a crucial role in carrying genetic information from one generation to the next. They contain the DNA, which encodes an individual's unique traits and characteristics. Chromosomes also aid in cell division and ensure the accurate distribution of genetic material to daughter cells during reproduction.

Yes all living things, (starting from a cell) have chromosomes. chromosomes are found in DNA and if cells didn't have DNA they wouldn't exist.
There are 38 chromosomes in a cat's diploid cell. Diploid cells always have an even number of chromosomes because they exist in pairs.
Allium cepa, also known as onion, has a total of 16 chromosomes. These chromosomes exist as eight pairs, with each pair consisting of two homologous chromosomes.
A somatic cell typically contains 46 individual chromosomes. These chromosomes exist in pairs, with one set inherited from each parent.
Chromosomes are usually found in pairs in most organisms, with one chromosome inherited from each parent. Humans have 23 pairs of chromosomes, for a total of 46 chromosomes. Exceptions do exist, such as sex chromosomes in some species.
diploid
It depends. If the chromosomes were suddenly taken out during the cell's cycle, it cannot reproduce. However, if you're talking about the development of a cell without chromosomes then the cell would simply not exist.
In humans, a single cell typically contains 46 chromosomes: 23 pairs, with one set inherited from each parent. These chromosomes house the genetic information required for proper cell function and development.
There are no homologous chromosomes in a haploid cell, as a haploid cell has only one set of chromosomes. One member of each pair of homologous chromosomes comes from one set, and the other member comes from the second set, so homologous chromosomes only exist in diploid cells.
After meiosis in a cell that originally has 46 chromosomes, each resulting nucleus will have 23 chromosomes. This is due to the process of meiosis, which involves two rounds of cell division that result in the formation of four daughter cells, each with half the number of chromosomes as the original cell.
No, DNA does not exist as a single chromosome in most organisms. Instead, DNA is typically organized into multiple chromosomes within the nucleus of a cell.
