Sexual reproduction involves two parent organisms.

Reproduction of multicellular organisms often involves sexual reproduction as well as asexual cell division. The table shows some differences between asexual and sexual reproduction.

Comparing Asexual and Sexual Reproduction
Asexual Reproduction Sexual Reproduction
Cell Division Cell division and other processes
One parent organism Two parent organisms
Rate of reproduction is rapid Rate of reproduction is slower than rate for asexual reproduction
Offspring identical to parent Offspring have genetic information from two parents

If you grow a plant from a cutting, the new plant will be identical to the parent. However, plants that grow from seeds contain genetic material from two parents. Plants growing from seeds and animals growing from eggs are examples of organisms that reproduce through sexual reproduction.

Cell division is part of both sexual and asexual reproduction. The process of mitosis produces cells identical to the parent cells. The diversity of life on Earth is in part possible because of the combining of genetic materials from two parents in sexual reproduction. In the next chapter, you will read about cell processes involved in sexual reproduction.
