2.1 Principles of Organisation

• Cells are the basic building blocks of life
• An organ consists of two or more tissues working together.


  True
• Match the tissue type with its function:

  Epithelial Tissue ↔️ Forms protective barriers

  Connective Tissue ↔️ Provides structural support

  Muscle Tissue ↔️ Enables movement

  Nervous Tissue ↔️ Transmits electrical signals
• Muscle tissue contracts to enable movement
• Nervous tissue transmits electrical signals for communication.

  True
• Arrange the steps of organ organisation from simplest to most complex:

  1️⃣ Arrangement of tissues

  2️⃣ Formation of specific organs

  3️⃣ Collaboration of organs in systems
• Muscle tissue in organs enables movement and function
• What are the functions of epithelial tissue in tissue organisation?

  Covers surfaces, forms glands
• Which tissue type provides structural framework and supports other tissues?

  Connective tissue
• Connective tissue connects organs and supports the body
• What are examples of muscle tissue?

  Skeletal, smooth muscles
• What are the functions of epithelial tissue?

  Covers surfaces, forms glands
• Muscle tissue contracts to enable movement
• What are examples of nervous tissue?

  Brain, spinal cord
• Organ organisation involves the arrangement of tissues to form specific organs
• Connective tissue in organs provides support and connects them.


  True
• System organisation refers to how organs and tissues work together to perform complex functions
• Why is specialization of cells, tissues, and organs important in cellular organization?

  Performs specific functions
• Organ systems maintain homeostasis through coordination and regulation.

  True
• The coordination and regulation between different organ systems is essential for maintaining homeostasis, a stable internal environment.homeostasis
• Cells perform basic life functions.Cells
• The hierarchical organization of the body is crucial for maintaining life.


  True
• Match the level of organization with its example:

  Cells ↔️ Epithelial cells

  Tissues ↔️ Connective tissue

  Organs ↔️ Stomach

  Organ Systems ↔️ Digestive system
• Nervous tissue coordinates body functions through electrical signals.


  True
• Organ organization involves the arrangement of tissues to form specific organs with unique functions and structural features.organs
• In system organization, organs interact and depend on each other to maintain balance.balance
• Muscle tissue enables movement
• Match the tissue type with its role and example:

  Epithelial Tissue ↔️ Protection and lining: Stomach lining

  Connective Tissue ↔️ Support and connection: Ligaments

  Muscle Tissue ↔️ Movement and function: Heart muscles

  Nervous Tissue ↔️ Signal transmission: Nerve cells in the brain
• Specialisation allows organs to perform specific tasks efficiently.


  True
• What is the function of the stomach in the digestive system?

  Breaks down food
• What role does the liver play in digestion?

  Produces bile
• Nerve cells are specialized to transmit electrical signals.


  True
• Organ systems maintain a stable internal environment called homeostasis
• What is the overall purpose of hierarchical organization in the body?

  Maintain complex processes
• What are nerve cells specialized to do?

  Transmit electrical signals
• Match the tissue type with its example:

  Epithelial Tissue ↔️ Skin

  Connective Tissue ↔️ Bone

  Muscle Tissue ↔️ Skeletal muscles

  Nervous Tissue ↔️ Brain
• The stomach is an example of an organ composed of multiple tissues.

  True
• What does cellular organisation refer to in biology?

  Arrangement of cells
• What is a tissue in the context of cellular organisation?

  Group of similar cells
• What is the function of organ systems in cellular organisation?

  Perform broad functions
