Blocks contain a summary of validated transactions that were made through a specific cryptocurrency network over a given period.

A private key is the PRIVATE portion of a wallets key pair. It is a long string of random characters that prove you have access to cryptocurrency in your wallet. Private keys allow you to spend cryptocurrency from a wallet; therefore, they must NEVER be revealed to anybody. This is especially the case for paper wallets, where your private key gets printed on a piece of paper (which can be sneakily photographed by somebody in an attempt to steal your coins. )
The public key of a wallet key pair is used to create an address to receive cryptocurrency. A public key is created from a private key in a key pair.
