In eukaryotes (animals, plants, fungi, algae) chromosomes are found in the nucleus.
There is also DNA in mitochondria and chloroplasts, which is usually referred to by terms like "mitochondrial DNA" or "the chloroplast genome". The word "chromosome" is not generally used for this DNA.
Prokaryotes (bacteria) have a single chromosome in a region of the cell called the nucleoid. Scientists do not use the term "nucleus" for prokaryotes, as there are no membranes inside the cell, and therefore no nuclear membrane. So, no nucleus!
The nucleus.

How many chromosomes are contained in a human male gamete cell?
In a gamete (sex) cell, there are 23 chromosomes. A gamete is a haploid, or n, whereas a somatic (normal) cell is a diploid, or 2n, and has 46 chromosomes.
How are sex cells different from other cell in the body?
Sex cells have 1/2 the number of chromosomes of a normal cell (23)
What does a cytogenesis do?
Branch of science that is concerned with the study of chromosomes and cell-division . It includes study of normal chromosomes and investigation of the chromosomal anamolies.
How is the nucleus of the sperm cell different to the nucleus in the body cell?
a gamete nucleus has only half the number of chromosomes in it than a regular body cell. in humans a regular body cell has 46 chromosomes (23 pairs) in the nucleus, but a gamete ie sperm or egg cell has only 23 chromosomes, which are all unpaired. during fertilization the 23 chromosomes from a sperm and the 23 from the egg cell combine and pair up.
How many chromosomes does each skin have?
each skin cell has 46 chromosomes
How many Pairs of chromosomes are located in the cell nucleus?
In a "normal" human autosome (normal cell, not a sex cell), there is 23 pairs of chromosomes.
How many chromosomes are in normal human sex cell?
There are 23 haploid chromosomes in a normal human gamete (sex cell).
How do the chromosomes of a sperm cell differ from chromosomes in other cells of the body?

How many chromosomes are in a baby's umbilical cord cell?
There are 46 chromosomes in the umbilical cord.
How many chromosomes are in a normal human sex cells?
There are 23 haploid chromosomes in a normal human gamete (sex cell).
A normal human body cell has a total of chromosomes chromosomes come from the mother and chromosomes come from the father?
A normal human body cell has a total of 46 chromosomes. 23 chromosomes come from the mother and 23 chromosomes come from the father, totaling to 46 chromosomes in total.
How many chromosomes are present in a normal human sex cell?
There are 23 haploid chromosomes in a normal human gamete (sex cell).
Normal human gametes carry how many chromosomes?
Normal human gametes carry 23 chromosomes, which is half the number of chromosomes found in a somatic cell. During fertilization, a sperm cell with 23 chromosomes fuses with an egg cell, also with 23 chromosomes, to form a zygote with a total of 46 chromosomes.
How many chromosomes are in a mature sex cell?
A sex cell contains half the number of chromosomes found in a somatic (normal) cell. Therefore a human sex cell would contain 23 chromosomes.
How many chromosomes are in a mature sperm cell?
A sex cell contains half the number of chromosomes found in a somatic (normal) cell. Therefore a human sex cell would contain 23 chromosomes.
How many chromosomes does a human cell have normally?
A human cell normally has 46 chromosomes, with 23 pairs - one set of chromosomes inherited from the mother and one set from the father.
How many chromosomes are present in each cell in this human?
There are 46 chromosomes in a normal human cell and 23 in the sex cells. People with down syndrome has 47 chromosomes.
