Animal and Plant Cells Worksheet featuring a labeled diagram of an animal cell with a word bank and identification questions.

This is a worksheet designed to test knowledge of animal cell anatomy. The task is to label the parts of the cell using the provided word bank and answer two questions about the cell type.

I will solve this by first identifying each labeled part of the cell, then answering the questions based on those identifications.

Step 1: Identify the Cell Type

The worksheet is titled "Animal and Plant Cells Worksheet," and the diagram shows a cell with specific organelles. To determine if it's an animal or plant cell, I need to look for key distinguishing features.

- Plant cells have a rigid cell wall, chloroplasts, and a large central vacuole.
- Animal cells do not have a cell wall or chloroplasts but have lysosomes and centrioles (though centrioles are not always shown).

Looking at the image, I can see:
- No visible cell wall (the outermost layer is the cell membrane).
- No chloroplasts.
- A prominent nucleus and other organelles like mitochondria, ER, Golgi body, etc.

This strongly suggests it is an animal cell.

Step 2: Label the Parts Using the Word Bank

The word bank contains: Mitochondria, Nucleus, Golgi Body, Cytoplasm, ER, Ribosome, Cell Membrane.

I will now identify each arrowed part:

1. Top center arrow pointing to the large purple structure: This is the Nucleus. It contains the cell's genetic material and is the control center of the cell.

2. Arrow pointing to the outer boundary of the cell: This is the Cell Membrane. It controls what enters and exits the cell.

3. Arrow pointing to the small, dot-like structures scattered in the cytoplasm: These are Ribosomes. They are responsible for protein synthesis.

4. Arrow pointing to the network of membranes near the nucleus: This is the ER (Endoplasmic Reticulum). It is involved in protein and lipid synthesis.

5. Arrow pointing to the stack of flattened sacs: This is the Golgi Body. It modifies, sorts, and packages proteins for secretion.

6. Arrow pointing to the oval-shaped organelles with inner folds: These are Mitochondria. They are the powerhouses of the cell, producing energy (ATP).

7. Arrow pointing to the gel-like substance filling the cell: This is the Cytoplasm. It is the material or protoplasm within a living cell, excluding the nucleus.

Step 3: Answer the Questions

Question 1: Which type of cell is this?

This is an animal cell.

Question 2: How do you know which type of cell it is?

I know this is an animal cell because it lacks a cell wall and chloroplasts, which are characteristic features of plant cells. Instead, it has a flexible cell membrane as its outer boundary and contains organelles like lysosomes and centrioles (though not all are labeled here), which are typical of animal cells.

Final Answer

Labeled Parts:
- Top center: Nucleus
- Outer boundary: Cell Membrane
- Small dots: Ribosome
- Network near nucleus: ER
- Stack of sacs: Golgi Body
- Oval organelles: Mitochondria
- Gel-like substance: Cytoplasm

Answers to Questions:
1. This is an animal cell.
2. I know this because it does not have a cell wall or chloroplasts, which are found in plant cells. The presence of a cell membrane as the outermost layer is characteristic of animal cells.
