Student Standard
(5) Science concepts. The student knows how an organism grows and the importance of cell differentiation. The student is expected to:
Task
(A) describe the stages of the cell cycle, including deoxyribonucleic acid (DNA) replication and mitosis, and the importance of the cell cycle to the growth of organisms;
1. Before a cell can go through mitosis, it must replicate (copy) its DNA. This occurs during the S phase of the Cell Cycle. Watch the video below to review the cell cycle.
2. If you need more of a review on DNA replication watch the video below.
3. Practice replication yourself. Click Here to try!

(B) examine specialized cells, including roots, stems, and leaves of plants; and animal cells such as blood, muscle, and epithelium;
Red and White blood cells
Leaf Cells with chloroplasts. What process occurs in chloroplasts and what are the reactants and products?
Skin cells: What process is occurring? How often do we replace our skin?

Cardiac (heart) cells
Stomata: openings on the underside of leaves What is the purpose of the stomata?
