Cells Practice Worksheet 2 | PDF | Cytoplasm | Cell (Biology) - Free Printable

Problem Analysis:

The worksheet provided is about identifying parts of a cell and determining whether it is an animal cell or a plant cell. The image shows a labeled diagram of a cell, and the task involves matching the labels with the correct cellular structures from the word bank.

#### Word Bank:
- Mitochondria
- Nucleus
- Golgi Body
- Cytoplasm
- ER (Endoplasmic Reticulum)
- Ribosome
- Cell Membrane

#### Diagram:
The diagram shows a cell with various labeled parts. The goal is to identify each part using the words from the word bank.

Solution:

#### Step 1: Identify the Type of Cell
1. Which type of cell is this?
- The diagram shows a cell without a cell wall, chloroplasts, or a large central vacuole. These are characteristic features of plant cells.
- Since the cell lacks these features, it is an animal cell.

2. How do you know which type of cell it is?
- Animal cells lack a cell wall, chloroplasts, and a large central vacuole, which are present in plant cells.
- The presence of structures like the nucleus, mitochondria, Golgi body, ER, ribosomes, and cell membrane confirms it is an animal cell.

#### Step 2: Label the Parts of the Cell
Using the word bank, match each label in the diagram with the correct cellular structure:

1. Top Left: This structure is rod-shaped and involved in energy production. It is the Mitochondria.
2. Top Center: This structure is a network of interconnected membranes. It is the ER (Endoplasmic Reticulum).
3. Top Right: This structure is responsible for modifying, sorting, and packaging proteins and lipids. It is the Golgi Body.
4. Middle Left: This structure is the control center of the cell and contains genetic material. It is the Nucleus.
5. Middle Right: This structure is the fluid matrix that fills the cell and contains organelles. It is the Cytoplasm.
6. Bottom Left: This structure is the boundary of the cell and regulates the movement of substances in and out. It is the Cell Membrane.
7. Bottom Right: These small structures are involved in protein synthesis. They are Ribosomes.

Final Answer:

1. Which type of cell is this?
- Animal Cell

2. How do you know which type of cell it is?
- The cell lacks a cell wall, chloroplasts, and a large central vacuole, which are characteristic features of plant cells.

#### Labeled Parts:
- Top Left: Mitochondria
- Top Center: ER (Endoplasmic Reticulum)
- Top Right: Golgi Body
- Middle Left: Nucleus
- Middle Right: Cytoplasm
- Bottom Left: Cell Membrane
- Bottom Right: Ribosomes

Final Answer Boxed:
