Classifying Organisms Worksheet for Middle and High School Level with Answer Key and Mnemonic.

Problem Overview:

The worksheet titled "Classifying Organisms" requires students to classify living organisms into the five kingdoms: Monera, Protista, Fungi, Plantae, and Animalia. The task involves filling out a table based on specific characteristics of each kingdom, such as cell type, source of nutrition, presence of a cell nucleus, number of cells, and presence of a cell wall. Additionally, students are asked to list examples of organisms in each kingdom.

Solution:

#### Step 1: Understand the Characteristics of Each Kingdom
We will fill out the table based on the provided characteristics for each kingdom. Here is the breakdown:

| Characteristic | Monera | Protista | Fungi | Plantae | Animalia |
|------------------------------|------------------|-------------------|-------------------|-------------------|--------------------|
| Cell Type | Prokaryotic | Eukaryotic | Eukaryotic | Eukaryotic | Eukaryotic |
| Source of Nutrition | Heterotrophic/Autotrophic | Heterotrophic/Autotrophic | Heterotrophic | Autotrophic | Heterotrophic |
| Cell Nucleus | Absent (no nucleus) | Present | Present | Present | Present |
| Number of Cells | Unicellular | Unicellular/Multicellular | Multicellular | Multicellular | Multicellular |
| Cell Wall | Present (peptidoglycan) | Present/Absent | Present (chitin) | Present (cellulose) | Absent |
| List Examples | Bacteria (e.g., *Escherichia coli*) | Algae, protozoa (e.g., *Amoeba*) | Yeast, mushrooms, molds | Pine tree, rose bush, kelp, moss | Mammals, birds, reptiles, fish, etc. |

#### Step 2: Fill Out the Table
Using the information above, we can complete the table as follows:

| Characteristic | Monera | Protista | Fungi | Plantae | Animalia |
|------------------------------|------------------|-------------------|-------------------|-------------------|--------------------|
| Cell Type | Prokaryotic | Eukaryotic | Eukaryotic | Eukaryotic | Eukaryotic |
| Source of Nutrition | Heterotrophic/Autotrophic | Heterotrophic/Autotrophic | Heterotrophic | Autotrophic | Heterotrophic |
| Cell Nucleus | Absent | Present | Present | Present | Present |
| Number of Cells | Unicellular | Unicellular/Multicellular | Multicellular | Multicellular | Multicellular |
| Cell Wall | Present | Present/Absent | Present | Present | Absent |
| List Examples | Bacteria | Algae, protozoa | Yeast, mushrooms, molds | Pine tree, rose bush, kelp, moss | Mammals, birds, reptiles, fish, etc. |

#### Step 3: List the Seven Levels of Classification
The seven levels of classification, from largest to smallest, are:
1. Kingdom
2. Phylum
3. Class
4. Order
5. Family
6. Genus
7. Species

A helpful mnemonic to remember these levels is:

Final Answer:

- Completed Table:
- See the breakdown above.
- Seven Levels of Classification:
- Kingdom, Phylum, Class, Order, Family, Genus, Species.
