3. Student Learning Map

  • Topic:05- Cellular Biology
  • Subject(s):Science
  • Days:20
  • Grade(s):9
Key Learning:

All living things are made up of one or more cells. Cells come in a variety of shapes and sizes that suit their diverse functions. Cell membranes help organisms maintain homeostasis by controlling what substances enter or leave cells.
Unit Essential Question(s):
 
 

How do the cells of prokaryotes and eukaryotes differ with respect to structure, function and reproduction?
   
Concept:

Cell Theory

SC.912.L.14.5   SC.912.L.14.1  

Discuss the contributions of Hooke and Leeuwenhoek in the discovery of cells.

Discuss the contributions of Schleiden, Schwann and Virchow in the historical development of the cell theory.

Emphasize the central principles of the cell theory and reinforce the idea that theories change as new evidence is discovered.
Concept:

Cell Structure and Function

SC.912.L.14.2   SC.912.L.14.3  

Discuss the terms prokaryote and eukaryote. Distinguish the characteristics between prokaryotic and eukaryotic cells and give examples of each.

Describe the structure and function of the cell organelles in an animal and plant cell. Structures to include are: cytoplasm, nucleus, cell membrane, cell wall, mitochondria, chloroplast, golgi bodies, vacuole, lysosomes, centrioles, ribosomes and endoplasmic reticulum (smooth and rough).

Compare and contrast the structure and function of plant and animal cells.

Discuss the special structures that unicellular organisms possess such as flagellum, pili, and cilia.

HOTS: Comparing/Contrasting or Error Analysis could be used to demonstrate the ET LEQ.
Concept:

Cell Transport

SC.912.L.14.2  

Briefly review the structure of the cell membrane.

Discuss the role of the cell membrane during passive transport including diffusion, osmosis (including isotonic, hypertonic and hypotonic solutions) and facilitated diffusion.

Discuss the role of the cell membrane during active transport including endocytosis (pinocytosis and phagocytosis) and exocytosis.

HOTS: Comparing/Constrasting or Error Analysis could be used to demonstrate the ET LEQ.

The Cell Cycle

SC.912.L.16.8   SC.912.L.16.15   SC.912.L.16.14  

Discuss cell division in prokaryotes (binary fission).

Identify the two types of cell division in eukaroytes (mitosis and meiosis). Meiosis should be mentioned but will not be studied within this unit.

Describe the events of the cell cycle including interphase (G1, S and G2) and cell division (mitosis and cytokinesis).

Discuss the relationship between mutation, uncontrolled cell growth and cancer.

Vocabulary Report

  • eukaryote -

    An organism made up of cells that have a nucleus enclosed by a membrane, multiple chromosomes, and a mitotic cycle; eukaryotes include animals, plants and fungi but not bacteria or archaea.

  • binary fission -

    A form of asexual reproduction in single-celled organisms by which one cell divides into two cells of the same size.

  • active transport -

    The movement of chemical substances, usually across the cell membrane, against a concentration gradient; requires cells to use energy.

  • *mitosis -

    A process of nuclear division in eukaryotic cells during which the

    nucleus of a cell divides into two nuclei, each with the same number

    of chromosomes.

  • passive transport -

    The movement of substances across a cell membrane without the use of energy by the cell.

  • prokaryote -

    A single-celled organism that has no nucleus and has no membrane bound organelles; examples include bacteria and archaea.

  • concentration gradient -

    A difference in the concentration of a substance across a distance.

  • *mutation -

    The process by which a gene undergoes a change in DNA sequence or a structural change.

  • *permeability -

    The capability of a porous substance or membrane to allow a fluid or gas to enter it; the measure or degree to which a substance can be penetrated by a liquid or gas.
