- Sperm are intended to fertilize the female sex cell, or egg. 精子是要令到雌性生殖细胞（者说是卵子）被受精。
- New life may begin to develop when a male sex cell (spermatozoon) unites with and thus fertilizes a female sex cell (ovum). 当一个雄性性细胞（精子）与一个雌性性细胞（卵子）相遇并因而受精的时候，新生命便开始发育。

- These sex cells contain only one set of chromosomes that combine during conception and create an embryonic cell with two chromosome sets, one from each parent. 这些性细胞各含一套染色体，形成胚胎细胞时，来自父本和母本的染色体则组合在一起。
- The soma's role is to get those sex cells, and thus the organism's genes, into the next generation. 这个躯体的角色是把那些性细胞，也就是生物基因，带到下一代。
- The soma (the ancient Greek word for body) is all of a body's cells apart from the sex cells. 躯体（这个词源于古希腊语中的身体）指的是除生殖细胞外其它体细胞的总和。
- In sexually reproducing organisms males and females produce sex cells, known as gametes. These are swimming sperm in males and ova (eggs) in females. 在性繁殖过程中，生物的雄性和雌性产生性细胞，称配子。雄性是能够游动的精子，雌性是卵子。

- The resulting glowing prairie voles were evidence that the embryos had indeed been altered, and that the alteration had been transmitted to every cell in the vole's body, including its sex cells. 她们使用病毒做为载体，将新的遗传物质载入草原田鼠的胚胎细胞。
