Question

reading tool make connections as you read the text, fill in the chart below to show how each idea is related to one another. specialized cells definition: example: tissues definition: example: organs definition: example: organ system definition: example:

Explanation:

• Specialized Cells:
• Definition: Cells that have specific structures and functions to perform particular tasks in the body.
• Example: Red blood cells (transport oxygen) or nerve cells (transmit electrical signals).
• Tissues:
• Definition: Groups of similar specialized cells that work together to perform a specific function.
• Example: Muscle tissue (composed of muscle cells, contracts to produce movement) or epithelial tissue (covers body surfaces and lines internal organs).
• Organs:
• Definition: Structures made up of different types of tissues that work together to perform a more complex function.
• Example: The heart (contains muscle tissue, connective tissue, etc., pumps blood) or the liver (performs various metabolic functions).
• Organ System:
• Definition: A group of organs that work together to perform a major body function.
• Example: The circulatory system (includes the heart, blood vessels, and blood, transports substances throughout the body) or the digestive system (involves organs like the stomach, intestines, etc., breaks down food).

Answer:

• Specialized Cells:
• Definition: Cells with specific structures/functions for tasks.
• Example: Red blood cells/nerve cells.
• Tissues:
• Definition: Groups of similar cells for a function.
• Example: Muscle/epithelial tissue.
• Organs:
• Definition: Structures of tissues for complex function.
• Example: Heart/liver.
• Organ System:
• Definition: Group of organs for a major function.
• Example: Circulatory/digestive system.
