No, their appearance remain changing during cell's life.
Somatic cells (of the body) are diploid (having 46 chromosomes). Only gametes (eggs and sperm) are haploid (having 23 chromosomes). So that during fertilization the egg and sperm combine their chromosomes resulting in a new life with 46 unique chromosomes (in humans, of course. Others species has differing numbers of chromosomes). The haploid combination ensures genetic diversity.
Scientists discovered that chromosomes are inherited in a predictable manner during cell division, they observed that the number of chromosomes in a species is constant, and that specific traits are linked to particular chromosomes. They also found evidence of chromosomes segregating independently during meiosis.
Human haploid cells contain half the number of chromosomes (23) compared to diploid cells (46). Haploid cells are involved in the formation of gametes (sperm and egg) during meiosis. In humans, haploid cells are only present in the gametes and not in somatic cells.
Then it's a prokaryote cell (such as bacteria). If not a prokaryote then it just wouldn't be a cell because with eukaryote cells, if there are no chromosomes, there is no cell or life with that cell.
No, the number of chromosomes remains constant throughout the human life cycle. Human cells have 46 chromosomes, with 23 inherited from each parent. This number is maintained through cell division and reproduction.
Only during the division stages of a cells life will chromosomes form. During Interphase the cells DNA is in the unorganized form of chromatin.

Yes, as a matter of fact, all living that reproduce via mitosis or meiosis will form chromosomes. Chromosomes are only formed during these ways of reproducing. At all other parts of a cell's life, chromosomes are stringy matter called chromatin.
Interphase. Cells spend the majority of the time in interphase, where they grow and perform their life functions.
The vehicle that transports the chromosomes from each parent to create a new human life is the sperm cell from the father and the egg cell from the mother. During fertilization, these two cells combine to form a zygote with a complete set of chromosomes.
Yes, chromosomes make copies of themselves through a process called DNA replication. During cell division, each chromosome is duplicated to ensure that each daughter cell receives an identical set of genetic material.
The interphase stage, specifically during the G1 phase when the cell is preparing for DNA replication, is ideal for photographing cells. This is because the cell's structures are visible and distinct during this phase before the DNA condenses into chromosomes during mitosis.
Haploid refers to having only one set of chromosomes, while diploid refers to having two sets of chromosomes. Body cells are diploid, while sex cells are haploid. In humans, diploid cells have two sets of 23 chromosomes for a total of 46, and haploid cells have one set of 23 chromosomes.

They also found evidence of chromosomes segregating independently during meiosis.
Human cells are diploid during the majority of their life cycle, including in somatic cells. This means they have two sets of chromosomes, one from each parent. The only exception is in reproductive cells (sperm and egg cells), which are haploid.
