Question 1 of 26

1

Single cells grow and ❌ to form more cells in a process called the ❌.

A ❌ cell undergoes cell division which promotes cell growth. The cells can then either grow into more stem cells or develop into specialized cells which in turn develop into ❌ cells.

❌ development causes many cells to ❌ the ability to divide as they develop into the tissues and organs that make up organisms. The cells that retain many embryonic properties are called ❌ stem cells.
