The Mandella Environment

Monday: B Day

Aim: What do all living things need?

Do Now: Copy chart from board

Procedure: Students will continue to discuss the nine life functions in detail.

Nutrition: Organisms obtain and process food/supplies energy

Transport: Circulation and absorption of nutrients/O, H2O, nutrients and waste move to and away from cell

Respiration: Chemical reactions that release energy for life activities/Aerobic-O and Anaerobic-no O

Excretion: Removal of waste materials because of respiration/CO2 and H2O

DONT CONFUSE Egestion: Getting rid of waste from digestion

Regulation: Control and coordination of all activities/Responding to stimuli Endocrine-Nervous systems

Synthesis: Producing a complex substance from simple substances/PHOTOSYNTHESIS

Growth: Increase in size and /or number of cells of an organism/

Reproduction: Making of a new organism/Extinction could occur in entire group does not reproduce but individual will not die without reproduction.

Metabolism: Total of all processes taking place within the cells of an organism/Homeostasis: Maintaining a stable internal environment regardless of changes externally. Organisms constantly strive for homeostasis.

Homework #19: Using your text try to label the organelles of the animal

Tuesday: A Day

Aim: What are the organelles of the cell? What is the function of these parts?

Do Now: Take the skill worksheet and a Glencoe Text to your desk.

Procedure: Students will interpret the diagrams of the animal and plant cell on page 33 of the text book. They will complete a chart asking for the cell part, the function and the location of that organelle. Have a specimen of an animal cell and a plant cell under a microscope for students to view and compare to their diagrams in the book. USing the video disc player show students various cells and their parts.

Homework #21: Label the parts of the animal cell using the diagram in your UPCO book on Page 65

Wednesday: B Day

Aim: How do we examine a plant cell?

Do Now: Students will gather their lab supplies for Lab #5. Page 77 (Observing cell structure)

Procedure: Students will locate various parts of a plant cell by createing a temporary wet mount of an onion plant. Another group of students will create a temporary wet mount of their cheek cells and the class will compare the most obvious differences between an animal and a plant cell.

Homework #20: Practice UPCO Book: Page 65 - Page 68 all Questions

Thursday: A Day

Aim: What are the differences between an animal and plant cell?

Do Now: Take a plant cell diagram to your desk.

Procedure: Using the overhead show the students the organelles in a plant cell. Discuss the differences between animal and plant cells.   Complete the organelle descriptions in your text Pages 69-73 all.

Homework #21: Define the scientific terms on page 79-80

Friday: B Day

Aim: How can we create an accurate replica of a cell.

Do Now: Lab teams will decide what materials they will use to create their gel cells.

Procedure: Create a key for your cell explaining what materials you chose, what organelle they will represent and construct your gel cell.

If extra time allows we will continue onto these notes: Certain cells in multicellular organisms have certain jobs. This is called cell specialization. Cell Organization: The cell is the basic unit of structure of all living things. Cells are grouped together in levels or units. These specialized units perform simlar functions. i.e. stomach cells, muscle cells, blood cells, etc.

  • Groups of cells make up tissue. (stomach tissue) Groups of similar tissue make up an organ. (stomach) A group of organs that work together to carry out  a major body function are the organ systems. (digestive system) All systems that perform the life functions make up an organism. (human) Describe cell organization using a pyramid on the board. Have students look at different cells under the microscope.

Students will continue to work in the UPCO book by completing the chart on Page 81. Organelles and their function.
