Cell Structure and Function SC.912.L.14.3 Compare and contrast the general structures of plant and animal cells. Compare and contrast the general structures of prokaryotic and eukaryotic cells. To the Teacher:

What do I need to know? How to compare and/or contrast the structures found in prokaryotic cells and in eukaryotic cells. How to compare and/or contrast the structures found in plant cells and in animal cells. Explain the role of the cell membrane during active and passive transport. To the Teacher:

Prokaryotic Cells vs Eukaryotic Cells All cells have three things in common: A cell membrane, cytoplasm and DNA Prokaryotic cells lack a nucleus and membrane-bound organelles. They tend to be smaller and more simplistic. Eukaryotic cells have a nucleus and membrane-bound organelles. They tend to be larger and more complex.

Prokaryotic Cells vs Eukaryotic Cells Guiding Questions: What are the similarities and differences between prokaryotic and eukaryotic cells? What are the structures that make up the eukaryotic cell? What function do each of theses structures provide to the cell? To the Teacher:

Plant Cells vs Animal Cells Eukaryotic Nucleus Ribosomes Mitochondria Golgi Apparatus Endoplasmic Reticulum Cell Membrane Cytoplasm Chloroplast Cell Wall Large Central Vacuole Centrioles To the Teacher:

Plant Cells vs Animal Cells 1) Guiding Questions: What structures do plant and animal cells have in common? 2) What structures differ between plant and animal cells? To the Teacher:

The Cell Membrane The cell membrane is a thin flexible layer that surrounds the cell, that is made up of a double layer of lipids and imbedded proteins. The cell membrane is selectively permeable and functions to control what enters and leaves the cell.

The Cell Membrane Guiding Questions: 1) What are the components that make up the cell membrane? 2) How do large and small molecules differ in their crossing of the cell membrane? 3) How do charged and uncharged molecules differ in their crossing of the cell membrane? To the Teacher:

Cell Transport There are two types of cellular transport: Active transport and Passive transport. Active transport requires the input of cellular energy and moves particles from a low concentration (hypotonic solution) to a high concentration (hypertonic solution). Examples include protein pumps, endocytosis and exocytosis Passive transport does not use cellular energy and moves particles from a high concentration (hypertonic solution) to a low concentration (hypotonic solution). Examples include diffusion, osmosis and facilitated diffusion. To the Teacher: Source: http://hyperphysics.phy-astr.gsu.edu/‌hbase/Biology/imgbio/actran2.gif

Cell Transport Guiding Questions: 1) How does passive transport and active transport differ in regards to energy usage and direction they move particle? 2) What are different examples of passive transport and active transport? 3) How do the different types of passive transport and active transport move molecules across the membrane? To the Teacher:
