Why is it important for cells to go through the cell cycle?
In order for our bodies to grow and develop, they must produce new cells and allow for the death of old cells. Cell division is also an essential component of injury repair. If our cells couldn't divide and create new cells, our bodies could never produce new skin cells to heal road rash, or grow a fingernail back.

What is the correct equation for photosynthesis?
A: Light energy+ 6CO2 + 6H2O → C6H12O6 + 6O
B: 6CO2 + 6H2O → C6H12O6 + 6O + Light energy
C: 12CO2 + 2H2O → 06H12O6 + 6O
A: Light energy+ 6CO2 + 6H2O → C6H12O6 + 6O

What do chloroplasts do?
It captures energy from sunlight and makes it into an energy form that cells can make into food.
500
What is the difference between endocytosis and exocytosis?
Endocytosis is cells taking in substances from outside the cell into the cell while exocytosis is where cells shift materials, such as waste products, from inside the cell to the outside.

What happens during mitosis?
One cell, the mother, divides to produce two new cells, the daughters, that are genetically identical to itself.
