What happens in G1?
Cell grows
200
What is produced by photosynthesis?
glucose and oxygen
200
which is used to create gametes?
meiosis

A cell with 46 chromosomes is going through mitosis. How many chromosomes will the daughter cell have?
46 - same
400
What happens in G2?
DNA checked for mistakes; if wrong, tries to correct or apoptosis
400
what is a biological process that adds oxygen to the atmosphere?
photosynthesis
400
a cell with 48 chromosomes is going through meiosis; how many chromosomes will the daughter cell have?
24; half
500
What happens in m-phase?
mitosis - cell splits
500
Why is there less carbon dioxide and more oxygen near a forest?
Because more photosynthesis is happening, and it uses co2 and a product is oxygen
