What is the difference between asexual
reproduction and sexual reproduction?
Sexual
• Requires two parents
• Babies have traits
from both parents
Asexual
• Requires only 1
parent
• Babies IDENTICAL to
parent
What is ATP, and why is it important
to a cell?
• ATP is the cell’s main energy chemical

give off heat. Is a flame alive?
Explain.
No
It cannot reproduce
