Learning Targets
Reminder: Use Quizlet to study vocabulary! https://quizlet.com/subject/rippin-biology/
Reminder: For Honors Biology students only.
1. Introduction to the Cell
a. I can describe the relationship between atoms, bonds, and molecules.
b. I can explain the hierarchy of structure found in living things.
c. I can cite evidence of the origin and evolution of cells and organelles.
2. Cell Organelles - How do organelles work to support the cell?
a. I can describe the function of the nucleus.
b. I can describe the functions of organelles that make or modify macromolecules: ribosomes, rough endoplasmic
reticulum, smooth endoplasmic reticulum, Golgi apparatus.
c. I can describe the functions of organelles that make energy for cell metabolism: mitochondria and chloroplasts.
d. I can describe the functions of organelles that store products in a cell: vacuoles and lysosomes.
e. I can describe the functions of the organelles that give the cell shape and structure: cell wall, cytoskeleton.
f. I can describe how all the organelles work together to make proteins.
3. Cell Types - How are all cells the same, yet different?
a. I can list differences between prokaryotic and eukaryotic cells.
b. I can list similarities and differences between animal and plant cells.
c. I can identify the organelles in prokaryotic and eukaryotic cells using diagrams.
d. I can list which organelles are in all cells.
e. I can explain how cells in a multicellular organism can be different even though they all contain the same DNA.
PLASMA MEMBRANE AND CELL TRANSPORT
4. Cell Size: - Why are cells so small?
a. I can explain why cells are microscopic.
b. I can explain why there is a limit to cell size.
c. I can explain why prokaryotic cells are smaller than eukaryotic cells.
5. Membrane Structure - How are macromolecules arranged to form a membrane?
a. I can identify the parts of the plasma membrane from diagrams.
b. I can list the function of each part of the plasma membrane.
c. I can show how all of the parts of the plasma membrane work together to make it selectively permeable.
d. I can explain how the plasma membrane and its components enable the cell to maintain homeostasis
6. Passive Transport - How do cells transport substances across a membrane without using energy?
a. I can explain what passive transport is and why cells do it.
b. I can describe osmosis, dialysis, and facilitated diffusion.
c. I can predict what will happen to plant and animal cells when placed in the following solutions: hypotonic, hypertonic,
and isotonic.
7. Active Transport - How do cells transport substances across a membrane using energy?
a. I can explain what active transport is and why cells do it.
b. I can describe the sodium/potassium pump, endocytosis and exocytosis.
8. Summary
a. I can use a neuron (nerve cell) to describe how passive and active transport work together to maintain homeostasis.
