SMART START – on page 24

Draw and fill in diagrams using word bank

Word Bank:

Cells

Organs

Organ Systems

Organism

Tissues

Let’s define those words! (pg. 22)

1. Molecule

2. Organelles

3. Cells

4. Tissues

5. Organs

6. Organ Systems

7. Organisms

A particle made up of atoms.

Structures that carry out life functions in cells

Basic unit of life

Groups of cells with the same function

A collection of different tissues that carry out life functions

Several organs working together.

A living thing.

Building Bodies Unit

Cells – Cell Types

Today’s Objectives

Compare and contrast eukaryotic and prokaryotic cells.

How we are going to do this?

Get into pairs

One person reads about prokaryotic cells the other person reads about eukaryotic cells.

As you read fill in the appropriate column on your t-chart

Get back together with your partner and teach her/him what you learned.

Listen to your partner’s lesson and fill out the other side of your t-chart.

Article & t-chart directions:

Read and discuss the short article with your small group.

Please don’t write on it!

As you read record the following information in the t-chart

Definition

Nucleus?

Size of the cell

Location of the DNA

Examples

Thursday 10/24

Get your notebook.

Take out the T-Chart from yesterday

Glue it to page 25

Fold it in half first

If you owe me anything and MANY of you do you need to stay for enrichment today, tomorrow, and/or Monday!

Comparing & Contrasting

Eukaryotic Prokaryotic

Tuesday 11/5

Take out your interim so we can finish going over it.

Thank you.

Wednesday 11/6

Get your notebook.

Please update your table of contents

◦ 11. Cell Types: Eukaryotic v. Prokaryotic

◦ 12. Cell Theory & Cell Parts

◦ 13. Animal Cells v. Plants Cells

On page 26 Record today’s objectives:

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.

What is a Cell?

A cell is the smallest unit that is capable of performing life functions.

What are the two types of cells?

Plant Cells

◦ Rectangular in shape

◦ Contain chloroplasts, cell wall, large vacuole

◦ Found only in plants

◦ Carry out photosynthesis

Animal Cells

◦ Rounded in shape

◦ Do not contain chloroplasts, cell wall, large vacuole

◦ Found only in animals

Examples of Cells

Amoeba proteus

Plant

Bacteria

Nerve Cell

Red Blood Cell

Cell Parts

Organelles

Surrounding the Cell…

(2 Parts)

Cell Membrane

Outer membrane of cell that controls movement in and out of the cell

Double layer- made of lipids (and protein) http://library.thinkquest.org/12413/structures.html

Cell Wall

Most commonly found in plant cells & bacteria

Supports & protects cells http://library.thinkquest.org/12413/structures.html

Inside the Cell…

(6 parts)

Nucleus

Directs cell activities

◦ Regulation!

Holds DNA

Separated from cytoplasm by nuclear membrane

Cytoplasm

Gel-like mixture

Surrounded by cell membrane

Contains dissolved food and oxygen

Ribosomes

Make proteins (Synthesis!)

Found on Rough ER & floating throughout the cell

◦ Cells contain thousands

Mitochondria

The “Powerhouse”

Produces energy through chemical reactions – breaking down carbohydrates

◦ This is Respiration! http://library.thinkquest.org/12413/structures.html

Vacuoles

Sacs for the storage of food water, and waste removal

Contains water solution

◦ Help plants maintain shape http://library.thinkquest.org/12413/structures.html

Chloroplast

Usually found in plant cells

Contains green chlorophyll

Where photosynthesis takes place http://library.thinkquest.org/12413/structures.html

Endoplasmic Reticulum

Network of membranes found throughout the cell

Assists with the packing and manufacturing of proteins

Golgi Apparatus

Gathers simple molecules and combines them together to make more complex molecules.

Helps the

Endoplasmic

Reticulum manufacture and package proteins.
