3. Student Learning Map

  • Topic:06 - Cell Structures and Functions
  • Subject(s):Science
  • Days:10
  • Grade(s):
Key Learning:  Cells form the foundation for all life processes.  All life begins with cells and the stuctures and activities that occur with an organism are the result of cellular processes.
Unit Essential Question(s):
 
 
How do plant and animal cells carry out life processes? 
   
Concept: Microscopes 

 Compare and contrast the structure and function of different types of microscopes.

Discuss how the object to be viewed influences what type of microscope a scientist will use.

Concept: Cell Theory

 State and explain the cell theory.

Cell organelle structure and function should be a review as it is taught at the middle school level.  Students should extend and refine their understanding.

Look at specialized cells and predict how their organelles allow them to perform specialized functions.

HOTS: Compare/Contrast, Inductive Reasoning,Classifying/Categorizing, Constructing Support or Deductive Reasoning could be used to address the ET LEQ.

Concept: Cell Transport

 Explain the role of the cell membrane as a highly selective barrier that regulates the movement of materials in and out of the cell.

Describe the process of passive transport and give examples of when itis used.

Discuss the process of active transport and give examples of when it is used.

HOTS: Compare/Contrast, Deductive Reasoning or Constructing Support could be used to address the ET LEQ.

How do we use passive transport to move materials across the cell membrane?  (A)
How is active transport useful in the movement of materials across the cell membrane?  (A)
What are the similarities and differences between active and passive transport?  (ET)
Concept: Cell Reproduction

 Discuss the various stages in the cell cycle.  Explain the different events that occur during each phase and describe how they impact the function of the cell.

Explain the various parts of mitosis.  Use models or diagrams to present each step in mitosis.  Be sure to discuss how at the end of mitosis the new cells are identical to the parent cell.

Discuss how mitosis can be used as a means of asexual reproduction in some unicellular organisms.

Explain how a mutation can impact the life cycle of a cell, including the potential for cancer.

HOTS: Deductive Reasoning, Inductive Reasoning, Constructing Support or Comparing/Contrasting could be used to address the ET LEQ.

Vocabulary Report

  • microscopy - Microscopy is the technical field of using microscopes to view samples or objects.  There are three well-known branches of microscopy: optical, electron, and scanning probe microscopy.
  • permeability - Permeability is a measure of the ability of a material to transmit fluids.  {A semipermeable membrane, also termed a selectively-permeable membrane, is a membrane that will allow certain molecules or ions to pass through it by diffusion and occasionally specialized "facilitated diffusion".  The rate of passage depends on the pressure, concentration, and temperature of the molecules or solutes on wither side, as well as the permeability of the membrane to each solute.  Depending on the membrane and the solute, permeability may depend on solute size, soluability, properties, or chemistry.  An example of a semi-permeable membrane is a lipid bilayer, on which is based the plasma membrane that surrounds all biologial cells.  Many natural and synthetic materials thicker that a membrane are also semipermeable.  An example of this is the film on the inside of an egg.}
  • concentration - The measure of how much of a given substance is mixed with another substance.  This can apply to any sort of chemical mixture, but most frequently the concept is limited to homogeneous solutions, where it refers to the amount of solute in a substance.
  • synthesis - The term synthesis is used in many fields, usually to mean a process which combines together two or more pre-existing elements resulting in the formation of something new.  Examples: (a) photosynthesis, the conversion of light enrgy into chemical energy by living rganisms; (b) DNA replication occurs during the S phase (synthesisi phase) of the cell cycle.
  • prokaryotic - Prokaryotic cells differ significantly from eukaryotic cells.  They don't have a membrane-bound nucleus and instead of having chromosomal DNA, their genetic information is in a circular loop called a plasmid.  Bacterial cells are very small, roughly the size of an animal mitochondrion.  Prokayotic cells feature three major shapes: rod, spherical, and spiral.  Instead of going through elaborate replication processes like eukaryotes, bacterial cells divide by binary fission.
  • homeostasis - The property to regulate the internal environment of the body so as to maintain a stable, sonstant condition.
  • eukaryotic - Animals, plants, fungi, and protists are eukaryotes, organisms whose cells are organized into complex structures enclosed within membranes.  The defing membrane-bound structure which differentiates eukaryotic cells from prokaryotic cells is the nucleus.  Many eukaryotic cells contain other membrane-bound organelles such as mitochondria, chloroplasts, and Golgi bodies.
  • phospholipid bilayer - A group of phospholipids (consisting of a phosphate head and 2 fatty-acid tails) arranged into a double-layer, with the hydrophilic phosphate heads exposed to the water content outside and within the cell, and the hydrophobic fatty-acid tails hidden in the inside.  [The phospholipid bilayer is the most permeable to small, uncharged solutes.  Protein channels float through the phospholipids, and collectively, this model is known as the fluid mosaic model.]
  • membrane - The cell membrane (aka plasma membrane, plasmalemma, or "phospholipid bilayer") is a selectively permeable lipid bilayer found in all cells. (1) It contains a wide variety of biological molecules, primarily proteins and lipids, which are involved in a vast array of cellular processes such as cell adhesion, ion channel conductance, and cell signaling; (2) It serves as the attachment point for both the intracellular cytoskeleton and, if present, the cell wall; (3) They separate the cell from the outside world; and (4) They separate compartments inside the cell to protect important processes and events.
