Level of organization in organism worksheet - Free Printable

Problem Analysis:

The task involves two main parts:
1. Labeling the diagram based on the levels of organization in an organism (Cells, Tissues, Organs, System).
2. Comparing and contrasting organs and organ systems by filling out a table.

---

Solution:

#### Part 1: Labeling the Diagram
The diagram shows a sequence of images representing different levels of biological organization. We need to label each image using the terms: Cells, Tissues, Organs, and System.

1. First Image (Single cell):
- This is a single cell, which is the basic unit of life.
- Label: Cells

2. Second Image (Group of similar cells):
- This shows a group of similar cells working together, forming a tissue.
- Label: Tissues

3. Third Image (Heart):
- The heart is an example of an organ, which is made up of different types of tissues working together to perform a specific function.
- Label: Organs

4. Fourth Image (Human body with circulatory system highlighted):
- This represents a system, such as the circulatory system, which consists of multiple organs working together to perform a complex function.
- Label: System

So, the labeled diagram will be:
- First box: Cells
- Second box: Tissues
- Third box: Organs
- Fourth box: System

#### Part 2: Compare and Contrast Organs and Organ Systems
We need to fill out the table by comparing and contrasting organs and organ systems based on the given criteria.

| Criteria | Organs | Organ Systems |
|---------------------------|----------------------------------|-----------------------------------|
| Group of | Tissues / Organs | Tissues / Organs |
| Carry out functions | Tissues / Organs | Tissues / Organs |
| Examples | Heart and flower | Circulatory system |
| Level of organization | Yes | Yes |

Explanation for Each Row:

1. Group of:
- Organs: An organ is a structure composed of two or more types of tissues working together to perform a specific function. For example, the heart is composed of muscle tissue, connective tissue, and epithelial tissue.
- Organ Systems: An organ system is a group of organs that work together to perform a complex function. For example, the circulatory system includes the heart, blood vessels, and blood.

2. Carry out functions:
- Organs: Organs perform specific functions. For example, the heart pumps blood, and a flower facilitates reproduction.
- Organ Systems: Organ systems also perform functions but at a higher level of complexity. For example, the circulatory system transports nutrients, oxygen, and waste throughout the body.

3. Examples:
- Organs: Examples include the heart (animal) and flower (plant).
- Organ Systems: Examples include the circulatory system (animal) and the reproductive system (animal/plant).

4. Level of organization:
- Both organs and organ systems are levels of organization within an organism. Therefore, the answer is "Yes" for both.

Final Answer:

#### Part 1: Labels
- Cells
- Tissues
- Organs
- System

#### Part 2: Table
| Criteria | Organs | Organ Systems |
|---------------------------|----------------------------------|-----------------------------------|
| Group of | Tissues / Organs | Tissues / Organs |
| Carry out functions | Tissues / Organs | Tissues / Organs |
| Examples | Heart and flower | Circulatory system |
| Level of organization | Yes | Yes |
