CELL BIOLOGY

1. The fundamental life processes of plants and animals depend on a variety of chemical reactions that occur in specialized areas of the organism?s cells. As a basis for understanding this concept:

c. Students know how prokaryotic cells, eukaryotic cells (including those from plants and animals), differ in complexity and general structure.

TASKS / OBJECTIVES:

1. Know the differences and similarities between prokaryotic and eukaryotic cells

2. Prokaryotic cells:

a. Be able to draw and label the parts of a prokaryote cell

b. Identify the parts of a prokaryotic cell and know their functions

c. Give examples of prokaryotic cells

3. Eukaryotic cells:

a. Be able to draw and label the parts of an ANIMAL eukaryote cell

i. Identify the organelles of an ANIMAL cell and know their functions

ii. Give examples of animal eukaryote cells

b. Be able to draw and label the parts of a PLANT cell and know their functions

i. Identify the organelles of an PLANT eukaryote cell

ii. Give examples of plant eukaryote cells

TIME FRAME: Three days

MATERIALS: Your textbook, Internet access, paper, writing tools, color pencils

INTRODUCTION:

Look at your hand (yes, LOOK at your hand). Now, touch it (yes, TOUCH your hand). DO IT. Feel the skin under your fingers? Have you EVER wonder?

1. What is the material that makes up my skin called?

2. What is it made up of?

3. Why does it hurt or bleed when it is injured?

4. Why does it heal and how does it happen?

5. How do I grow? How did I become the person I am today from the embryo that grew up inside my mother?s womb?

The answers to all these questions: CELLS

1. CELLS are the smallest units of LIFE that make up living things.

2. ALL living things are made up of cells

3. UNICELLULAR organisms: 1 cell only

4. MULTICELLULAR organisms: more than 1 cell (guess how many cells you have).

There are two main types of cells: prokaryotes (very primitive and simple) and eukaryote (more modern and complex).

Your task is to develop an understanding of each one of these two types of cells J

PROKARYOTES versus EUKARYOTES

http://www.cod.edu/people/faculty/fancher/prokeuk.htm (ONLY READ UNTIL POINT #5)

1. What does ?Karyose? mean and how does it relate to PROKARYOTE and EUKARYOTE (give me their definitions)?

2. What is one very important difference between prokaryotes and eukaryotes?

3. LIST 5 similarities between prokaryotes and eukaryotes

4. LIST 5 things that are different between prokaryotes and eukaryotes

PROKARYOTES

1. Use one of the three sites above (or other of your choice) to DRAW and LABEL a prokaryote cell:

a. Label the following: capsule, cell wall, cytoplasm, NUCLEOID (they don?t have nucleus), plasma membrane, ribosomes, flagella, pili.
Make the drawing large and use rulers to label it.

b. LIST their names and write their functions (what do they do?): capsule, cell wall, cytoplasm, plasma membrane, ribosomes, flagella, pili,

2. Give me an example of a prokaryote cell (look in your book or Internet).

EUKARYOTES (ANIMAL CELLS)

http://biology--dev.about.com/od/cellbiology/ss/animal_cells.htm

1. Use one of these sites (or other of your choice) to DRAW and LABEL an animal eukaryote cell:

a. Label the following: plasma membrane, cytoplasm, nucleus, nucleolus, rough endoplasmic reticulum, smooth endoplasmic reticulum, Golgi apparatus (complex), ribosomes, mitochondrion

b. LIST and write their functions (9 total)

EUKARYOTES (PLANT CELLS)

http://www.diffen.com/difference/Animal_Cell_vs_Plant_Cell

1. Use one of these sites (or other of your choice) to DRAW and LABEL a plant eukaryote cell:

a. Label the following: plasma membrane, cell wall cytoplasm, nucleus, nucleolus, rough endoplasmic reticulum, smooth endoplasmic reticulum, Golgi apparatus (complex), ribosomes, mitochondrion, chloroplast, vacuole.

b. Which 3 organelles are present in plant cells but not in animal cells? LIST them and write down their function.

Prokaryotic Cells Prokaryote is a cell or an organism that lacks a nucleus and other membrane enclosed organelles and most of their DNA is a single circular molecule. All bacteria are prokaryotic cells. The word "prokaryote" means "before the nucleus"...
