Q

Another type of Stem Cell?

A

Adult - stem cells are found in tissues and organs in the body. Adult stem cells have been found in many tissues such as bone marrow, brain, skeletal muscles, blood vessels and the heart. They are built in repair kits, regenerating surrounding cells damaged by disease, injury and everyday wear and tear.

17
Q

What are Meristems?

A

Meristems are the site of the production of non-specialised cell in plants.

18
Q

Where can meristems be found?

A
