ESS/FOCUS QUESTIONS
Essential Questions:
How are organisms structured to ensure efficiency and survival?
Focus Questions:
What are the two basic types of cells?
What is the nucleus? Is it an essential component of all cells?
How is a nucleus an evolutionary adaptation?
What is the importance of the cell membrane? Which structures are common/unique to both prokaryotes and eukaryotes?
What are the functions of these structures?
What is the cell cycle?
How is genetic material passed on through cellular reproduction?
------
CONTENT
1. The two basic cell types are prokaryote and eukaryote.
2. The nucleus is a membrane-bound organelle containg the genetic material in a
eukaryotic cell.
3. The regulation of genetic expression is enhanced by the development of the
nucleus.
4. Cells are enclosed by semi-permeable membranes which regulate movement of
materials between the cell and its environment.
5. Intercellular junctions connect cells within a tissue.
6. Passive and active transport are processes responsible for the movement of
essential molecules between a cell and its environment.
7. Prokaryotic and eukaryotic cells differ in complexity and general structure.
8. The endoplasmic reticulum and golgi apparatus are part of the endomembrane
system which functions in the secretion of macromolecules.
9. The ribosomes, DNA, and RNA work together to carry out the process of protein
synthesis.
10. Light energy is captured by chloroplasts, converted to chemical energy, and
stored in carbohydrate molecules. 11. Mitochondria are the site of cellular respiration; here the bonds of an organic
compound are broken and free energy is released.
12. Microtubules and microfilaments are involved with intracellular and extracellular
movement.
13. Cell growth is largely determined by the surface area-to-volume ratio.
14. DNA must be replicated prior to mitotic cell division.
15. Prokaryotic cellular reproduction involves binary fission.
16. The eukaryotic cell cycle is divided into interphase, mitotic events, and
cytokinesis.
17. The eukaryotic cell cycle is regulated by chemical checkpoints. Cancer results
from the malfunction of these checkpoints.

SKILLS
Students will be able to:
1. Explain that cells are the basic structural and functional units of life.
2. Distinguish between the two major cell types (prokaryotic and eukaryotic)
3. Explain the various methods by which cells transport substances across the cell
membrane, incuding simple diffusion, osmosis, facilitated diffusion, and active
transport.
4. Discuss and trace the interactions between various organelles and the cell
membrane.
5. Calculate the surface area-to-volume ratio of a growing cell.
6. Identify three different types of intercellular junctions and provide examples of each.
7. Describe the events of the cell cycle, including interphase, mitosis and cytokinesis. 8. Relate the events of the cell cycle to cancer.
