Somatic cells are all the cells that make up an organism, including the organ, muscle, fat, bone, and skin cells. The only exceptions are the egg and sperm cells, also called germ cells, which are involved in sexual reproduction. Although somatic cells differ greatly in their form and func...
Sperm are male gametes, reproductive cells that contain half a set of chromosomes that can be joined with a female gamete to form a zygote. If allowed to develop, the zygote will turn into an embryo and eventually will mature into a baby. Male gametes are found in semen, a fluid produced...
Step-by-Step Solution:1. Definition of Sperm and Egg: - Sperm is the male gamete, while the egg (ovum) is the female gamete in humans.2. Chromosome Composition: - Sperm cells conta
A fertilized egg is called a zygote. Specifically, a zygote is the single cell created when the sperm and egg combine. Once it is created, the zygote...Become a member and unlock all Study Answers Try it risk-free for 30 days Try it risk-free Ask a question Our experts can answer...
spermatozoa consist of a head and at least one flagellum or tail, which allows them to move independently. The head contains very little cytoplasm compared to other cells and carries very densely packedchromosomeswithin thenucleus. Like all sex cells,spermcells are haploid, containing only half the...
time of fertilization, it has only one cell (made when the sperm cell combines with the egg cell). "The genetic information in these cells then causes the zygote to start dividing," says Dr. Richlin. Essentially, the single cell will become two cells, then four, then eight, and so on...
Egg cells, or ova, are the cells utilized by female organisms to reproduce offspring. In contrast, the reproductive cells used by males are referred to as sperm. In mammals, a new individual is formed when an egg from the mother and a sperm from the father come together and allow their ...
Gametic incompatibility: a barrier to sexual reproduction where the sex cells (gametes) of a male (sperm) and female (egg) are too different to allow fertilization. Once two populations have diverged and begin evolving independently, eventually their members will become incapable of interbreeding...
