Objectives

Students will discuss the development of cell theory.Students will be able to discriminate between living and

non-living things.Students will draw and animal and plant cell and label it’s

parts.Students will make a foldable of the organelles of both

and practice naming them on an unmarked poster.Students will practice explaining the function of these

organelles.

Study for the test for a while….

After the test…Turn your test and answer sheet in to

me…I will have bell work on the screen..You will need:Your notebook, a textbook and

something to write with

BELL WORKFIND HOOKE’S CELL THEORY

IN YOUR TEXTBOOK AND LIST THE 3 STATEMENTS

(ON PAGE 71)

Today you need:notebook, pen or pencil, textbook

Cell Structure & Function

A CELL IS THE SMALLEST UNIT THAT

IS CAPABLE OF PERFORMING LIFE

FUNCTIONS.

What’s a cell?

Cell timeline

Hooke’s - Cell Theory

All living things are made up of cells.

Cells are the smallest working units of all living things.

All cells come from preexisting cells through cell division.

Are they made of cells?

people?cats?tomatoes?Mushrooms?Bacteria?The desk?Your pencil?

Today you need: colors to share, 3 big white papers, 1 tiny white paper, pencil

Bell work:Study your notes on the difference between prokaryotes and eukaryotes…we will be having a quiz on it today

Test grades

Retests:Offered Monday the 22nd at 8Or during your lunch (bring something to eat)You will need a pass to get up the hall. (In front)

You can retake it regardless of your grade (passing or failing)

The test is 4 essay questionsThe questions with answers are on my calendar on the

date of the retest.

Examples of Cells

Amoeba Proteus

Plant Stem

Red Blood Cell

Nerve Cell

Bacteria

Can you guess what the 5 groups of living things are?

You need: notebook, pen or pencil

No bell work…take a chill…..come see me if you missed the test…

Cells have an internal structure.

The cytoskeleton has many functions. supports and shapes cell helps position and transport organelles

provides strength assists in cell division aids in cell movement

organelles

“little organs”Membrane (skin) bound structures inside the cell.

Different in each kind of cellAll have different functions or jobs

•Prokaryotes•Prokaryotes EukaryotesEukaryotes

No organellesNo nucleusBacteria onlyEvolved firstSmall and simpleSingle celled

Have organellesHave a nucleusAll others (animals,

plants, fungus and protists)

Evolved laterMore complex

Two Types of Cells

Let’s draw some cells….We are going to draw a colored

plant and animal cell, label all the organelles and learn what each

of them do!

How to set up organelle sheets

1. Number the organelles on your plant and animal cell sheets as show on the overhead screen

2. Do not number amytoplast or centrosome on the plant cell –( draw a thin line through both of them)

3. Go to 2 fresh pages of your notebook (left and right)

4. Title the page “Animal Cell Organelles”

5. On the left, list 1-13 as shown on the next slide

6. Go to 2 more fresh pages and title them “Plant Cell Organelles”

7. List 1-13 as shown

8. Add the definitions as shown & we will practice…

Animal cell organelles1. Cell Membrane 8. Centrosome

2. Lysosome 9.Cytoplasm

3. nucleus 10. Rough E.R.(Endoplasmic Reticulum

4. Nucleolus 11. Smooth ER

5. Nuclear Membrane 12. Ribosomes

6. Vacuole 13. Golgi Body

7. Mitochondria

Plant cell organelles

1. Cell Wall 8. Mitochondria

2. Cell Membrane 9. Cytoplasm

3. Vacuole 10. Rough ER

4. Nucleus 11. Smooth ER

5. Nucleolus 12. Ribosomes

6. Nuclear Membrane 13. Golgi Body

7. Chloroplast (amyloplast/centrosome)

Function of plant organelles

1. hard cellulose (carb) outer layer2. wraps cell, controls in & out

3. stores water, food & waste

4.control center (holds DNA)5. center of nucleus6. wraps nucleus

7. Makes energy from sun by photosynthesis

8. Makes energy by cellular respiration9. holds organelles (jelly)10. E.R. with ribosomes11. E.R without ribosomes12. Makes proteins (cells) (from amino

acids) 13. Customizes proteins

Function of animal organelles

1. wraps cell, controls in & out2. digests (eats) waste3. control center (holds DNA)4. center of nucleus5. wraps nucleus6. stores water, food & waste7. makes energy by cellular respiration

Function of animal organelles

8. pulls genetic material apart in cell division

9. holds organelles (jelly)10. E.R. with ribosomes11. ER without ribosomes12. makes proteins (cells) from amino

acids13. customizes proteins

Bacteria

We are not learning the parts…Let’s look at the differences…be ready to identify a bacteria when you see one.

Is it a prokaryote or eukaryote?How can you tell by looking at this drawing?

Worksheet:

copy the worksheet onto your paperUsing your notes to complete the top of the worksheet

Do these exist in plants, animals or both? X for yes

Now answer the 4 questions at the bottom.
