Find and Replace Macro Based on Specific Cells

Hello all. After much fretting over this (and many other Excel issues), I've decided to seek out some assistance. I've included an example with columns, because I'm not very fluent in Excel terminology.

Worksheet 1

	1	        2
A	Able	        Apple
B	Baker	        Bacon
C	Charlie	        Chicken
D	Delta	        Duck


Worksheet 2

	1	         2
A	Alpha	        Apricot

I want to create a macro that will take the text from A1 on worksheet 2, find that text on worksheet 1, then replace A2 on worksheet 1 with A2 on worksheet 2.

In other words, I want the macro to (in this example), find "Alpha" in worksheet 1, then replace "Apple" on worksheet 1 with "Apricot" from worksheet 2.

Apologies if this is not clear: I'm still having trouble expressing myself when it comes to Excel.
