What are the major differences between the male and female reproductive systems? and here's a tougher question—what are the similarities? which structures are homologous vs which structures are derived from the same embryonic tissues?

Differences between the male and female reproductive system include:
Males continuously produce sperm, while females are born with all her eggs completely formed.
Males produce sperms, while the females produce ovums 
Females undergo menstruation while male do not
Similarities includes;
The reproductive organs of both develop from similar embryonic tissue and therefore, they are homologous
They both mature during puberty, when sex hormones are released.
They both have the gonads
They both secrete sex hormones

Reproductive sex organs for both male and female are derived from the same embryonic tissues and therefore they are considered homologous tissues or organs. 

Specific incident in Powell life is when he took a summer job as a porter in Pepsi's Long Island plant which he shows how his job was hard and demanding, but he worked hard and got a decent pay.

The incident was so important for Powell because it was a job done by Black people but he didn't care. He just wanted to work. He was happy to help no matter what it was and who he was with. He was given a job bottling machines at the plant which was reserved for White folks the following year. He did not care about racial segregation
