Question

chromosome number
for each cell, write haploid or diploid...
skin cell
egg cell
liver cell
sperm cell
brain cell

Explanation:

• Skin Cell: Skin cells are somatic cells. Somatic cells in humans have two sets of chromosomes (one from each parent), so they are diploid.
• Egg Cell: Egg cells are gametes. Gametes are produced through meiosis, which halves the chromosome number. So, egg cells are haploid.
• Liver Cell: Liver cells are also somatic cells. Like other somatic cells (e.g., skin cells), they have a full set of paired chromosomes, making them diploid.
• Sperm Cell: Sperm cells are male gametes. Similar to egg cells, they are formed via meiosis, resulting in a haploid chromosome number.
• Brain Cell: Brain cells (neurons, glial cells etc.) are somatic cells. They contain two sets of chromosomes (diploid) as they are not involved in sexual reproduction (unlike gametes).

Answer:

Skin Cell: diploid
Egg Cell: haploid
Liver Cell: diploid
Sperm Cell: haploid
Brain Cell: diploid
