Classification of the Five Kingdoms: A worksheet for students to complete with key features of each kingdom, including images and descriptive columns.

Let's complete the table based on the five-kingdom classification system proposed by Robert Whittaker. This system groups living organisms into five kingdoms: Animalia, Plantae, Fungi, Protista, and Prokaryotes (often referred to as Monera).

We’ll fill in each row with key features:

✔ Completed Table

| Kingdom | Examples | Multicellular or unicellular? | Presence of a cell wall | Can they make their own food? | Do they have a nucleus? |
|---------------|------------------------------|-------------------------------|--------------------------|-------------------------------|--------------------------|
| Animal | Cat, dog, human, bird | Multicellular | No | No | Yes |
| Plant | Rose, tree, fern, moss | Multicellular | Yes (cellulose) | Yes (photosynthesis) | Yes |
| Fungi | Mushroom, yeast, mold | Mostly multicellular (some unicellular like yeast) | Yes (chitin) | No (heterotrophs) | Yes |
| Protista | Amoeba, Paramecium, Euglena | Mostly unicellular (some colonial) | Some have cell walls (e.g., diatoms), others don't | Varies (some can, e.g., *Euglena*; some can't) | Yes |
| Prokaryotes | Bacteria, Archaea | Mostly unicellular | Yes (peptidoglycan) | Some can (e.g., cyanobacteria) | No (no membrane-bound nucleus) |

🔍 Explanation for Each Kingdom:

#### 1. Animalia
- Examples: Cats, dogs, humans — all animals.
- Multicellular: All animals are made of many cells.
- Cell Wall: No — animal cells only have a cell membrane.
- Make their own food? No — they are heterotrophs (must consume food).
- Nucleus? Yes — they are eukaryotes.

#### 2. Plantae
- Examples: Trees, flowers, ferns.
- Multicellular: Yes — plants are complex multicellular organisms.
- Cell Wall: Yes — made of cellulose.
- Make their own food? Yes — via photosynthesis using chlorophyll.
- Nucleus? Yes — they are eukaryotes.

#### 3. Fungi
- Examples: Mushrooms, yeast, molds.
- Multicellular or unicellular? Most fungi are multicellular (like mushrooms), but yeast is unicellular.
- Cell Wall: Yes — made of chitin (same material as insect exoskeletons).
- Make their own food? No — they absorb nutrients from dead or living organisms (saprophytic or parasitic).
- Nucleus? Yes — fungi are eukaryotes.

#### 4. Protista
- Examples: *Amoeba*, *Paramecium*, *Euglena*, *Chlamydomonas*.
- Multicellular or unicellular? Mostly unicellular, though some form colonies.
- Cell Wall: Varies — some protists (like algae) have cell walls (made of cellulose), others do not.
- Make their own food? Varies:
- Some (like *Euglena*) are autotrophic (can photosynthesize).
- Others (like *Amoeba*) are heterotrophic (consume food).
- Nucleus? Yes — all protists are eukaryotes.

#### 5. Prokaryotes (Monera)
- Examples: *Escherichia coli*, *Streptococcus*, *Cyanobacteria*.
- Multicellular or unicellular? Almost always unicellular.
- Cell Wall: Yes — made of peptidoglycan (except in some archaea).
- Make their own food? Some can (e.g., cyanobacteria perform photosynthesis); others are heterotrophs.
- Nucleus? No — they lack a membrane-bound nucleus (they are prokaryotes).

📌 Summary Notes:

- Eukaryotes = Have a nucleus → Animal, Plant, Fungi, Protista.
- Prokaryotes = No nucleus → Prokaryotes.
- Autotrophs = Make their own food → Plants, some Protista, some Prokaryotes.
- Heterotrophs = Must consume food → Animals, Fungi, some Protista, some Prokaryotes.
- Cell wall composition varies:
- Plants → Cellulose
- Fungi → Chitin
- Prokaryotes → Peptidoglycan

✔ This table now reflects the key distinguishing features of each of the five kingdoms. You can use it to compare and contrast life forms across different kingdoms!
