Verified step by step guidance

Understand the term 'conception' in the context of human reproduction. Conception refers to the process where a sperm cell fertilizes an oocyte (egg cell), leading to the formation of a zygote.

Recognize that the statement 'Conception is the moment an embryo begins to develop' is misleading. The development of an embryo begins after conception, during the stages of cell division and differentiation.

Evaluate the options provided to correct the statement. The option 'False: Conception is the moment an oocyte is fertilized by a sperm cell' accurately describes the biological process of conception.

Consider why the other options are incorrect: 'Conception is the moment a person discovers they are pregnant' is incorrect because pregnancy detection occurs after conception. 'Conception is the act of sexual intercourse' is incorrect because conception specifically refers to fertilization, not the act itself.

Conclude that the correct understanding of conception is crucial for comprehending the initial stages of human development, emphasizing the importance of fertilization in the reproductive process.
