False (B)
How does the arrangement of cells in connective tissue contribute to its function?
How does the arrangement of cells in connective tissue contribute to its function?
The widely spaced cells in connective tissue, surrounded by a matrix, allow it to connect other tissue types and provide structural support.

Study Notes
Cells and Tissues
- All organisms are composed of cells working together for structure and function.
- Cells form tissues.
Tissue Types
- Tissues are groups of similar cells working together.
- Four main types:
1. Epithelial Tissue
- Structure: Tightly packed cells.
- Function: Covers body surfaces and lines organs, offering protection and absorption.
- Examples: Skin, intestine lining
2. Connective Tissue
- Structure: Widely spaced cells surrounded by a matrix.
- Function: Connects and supports other tissues, providing structure.
- Examples: Blood, bone, cartilage
3. Muscular Tissue
- Structure: Long, thin, closely associated muscle cells.
- Function: Coordinated movement through intercellular communication.
- Examples: Hamstring muscle, shoulder muscle
4. Nervous Tissue
- Structure: Neurons (star-shaped nerve cells).
- Function: Sends nerve impulses to control muscles, organs, and glands.
- Examples: Brain, spinal cord, nerves
Viewing Cells and Tissues
- Microscopes are required to view cells and tissues.
- Microscopes use a series of lenses to magnify.
Magnification
- Ocular Lens: The lens you look into.
- Objective Lens: The lens nearest the specimen.
- Total Magnification: Calculated by multiplying ocular magnification by objective magnification.
Characteristics and Functions of Muscular Tissue
- Skeletal Muscle: Voluntary, moves bones.
- Cardiac Muscle: Involuntary, pumps the heart.
- Smooth Muscle: Involuntary, controls organs.
Epithelial vs. Connective Tissue
- Epithelial Tissue: Cells are tightly packed, covers surfaces, protects, and absorbs.
- Connective Tissue: Cells are spaced apart, supports and connects tissues, providing structure and storing energy.
