Need vs need to! what's the difference between two words?

[Polyester]

Hi all
I need an apple.
I need to an apple.

Which one is correct? And why?
What's the meaning when I'm using "need to"?

Thank you for your advice!

I need something or somebody but
I need to do something.

[STRIKE]I need to a apple.[/STRIKE] This does not make sense.

[STRIKE]What's the meaning when I'm using[/STRIKE] When can I use "need to"?

Polyester, do you know how to decide when to use "a" and when to use "an"?

a,e,i,o,u there words are using an. Other words use a.

You wrote "a apple" twice in your first post.

So, it's ok now.
Can you help me on this question?
I'm still confused.
