Given what we know, we can confirm that the statement in the question is in fact true, by the end of the eighth week, the embryo is only 1 inch long and weighs just 1 gram.
<h3>What else do we know about the
embryo in this time frame?</h3>
During the first eight weeks, the embryo undergoes many changes. At this time:
- The legs and arms have formed.
- The fingers and toes are beginning to develop.
- It begins to be called a fetus.
- It is developing the lungs and lymphatic system.
- and much more.
Therefore, we can confirm that the statement that by the end of the eighth week, the embryo is only 1 inch long and weighs just 1 gram, is in fact true.

I hope this answer helps.
