Sperms and root hairs are both examples of haploid cells. Haploid cells are cells that contain half the number of chromosomes as a diploid cell. In humans, diploid cells contain 46 chromosomes, while haploid cells contain 23 chromosomes. Sperms are haploid cells that are produced by the testes. They are released during ejaculation and travel through the female reproductive tract to the fallopian tubes, where they can fertilize an egg. Root hairs are haploid cells that are produced by the roots of plants. They help the plant to absorb water and nutrients from the soil.
