For every transaction you make, you need the private key of your address to sign the transaction.
When you make a transaction, your seed phrase isn't directly used for signing the transaction. Your seed phrase (which is a series of words) is used to create a seed. Then the seed is used for generating the extended private key and the extended private key is used for generating your private key(s).
So, Any seed phrase gives you access to numerous addresses. But a private key gives you access to one address only (of course, more addresses if different script types are considered)
It should be noted that your private key(s) can be derived from your seed phrase. But your seed phrase can't be derived from your private key(s).

In basic terms a seed phrase is a representation of the private keys in an easily readable format in which you can back it up. Handling private keys would be difficult for most to write down and store without errors, so the seed or recovery phrase encodes the same information contained in the private key in a more user friendly format for easier recovery of an asset.
A seed phrase is a group of 12 - 24 words, while a private key is a combination of 51 or 52 alphanumeric characters.
