1. How do mitosis and meiosis differ?
Meiosis Both Mitosis
- Reproductive cells
- Nucleus divides 2x
- results in 4 haploid cells
- importance: forms egg & sperm cells
- Start with diploid cell
-Cell division: cell & nucleus divide
- DNA replicates & is passed on
-Body cells
- nucleus divides 1x
- results in 2 diploid cells (identical)
- importance: growth, repair, reproduction (single-celled)
How many cells result from the mitotic phase (mitosis & cytokinesis)?
A. 1
B. 2
C. 3
