Flashcard 1: Choose the statement that correctly links cell specialization to tissue formation.
Answer: Specialized cells with similar structure group to do one function. Specialization enables tissue-level organization.
Flashcard 2: Identify the best evidence that the stomach is an organ made of multiple tissues.
Answer: It has muscle for churning and epithelium for secretion/lining. Two distinct tissue types prove organ status.
Flashcard 3: Which option best describes how tissues in an organ depend on each other?
Answer: Each tissue performs a role that supports the organ’s function. Tissues work together for organ's overall function.
Flashcard 4: Which statement best describes a key difference between a tissue and an organ?
Answer: Tissue: similar cells; organ: multiple tissue types. Tissues have one cell type; organs have many.
Flashcard 5: What evidence shows that cells in a tissue are specialized for the same function?
Answer: They share similar structure and perform the same task. Matching structures indicate matching functions.
Flashcard 6: What is the correct order of biological organization from cell to organ system?
Answer: Cell → tissue → organ → organ system. Shows increasing complexity from smallest to largest unit.
Flashcard 7: What is a tissue in multicellular organisms?
Answer: A group of similar cells working together for a function. Cells with same structure unite for one purpose.
Flashcard 8: What is an organ in multicellular organisms?
Answer: A structure made of multiple tissues working together. Different tissue types combine for complex functions.
Flashcard 9: Which type of evidence best supports that tissues form organs?
Answer: Organs contain several tissue types with different roles. Multiple tissue types prove organ-level organization.
Flashcard 10: Which option is the best example of a tissue (not an organ): muscle, heart, stomach, skin?
Answer: Muscle. Only muscle is a single tissue type; others are organs.
Flashcard 11: Which option is the best example of an organ (not a tissue): blood, epithelium, heart, cartilage?
Answer: Heart. Heart has multiple tissue types; others are single tissues.
Flashcard 12: What is the main function of epithelial tissue in organs?
Answer: Covers and lines surfaces; protection and absorption. Forms barriers and allows selective exchange.
Flashcard 13: What is the main function of muscle tissue in organs?
Answer: Contracts to produce movement and force. Enables organs to move or pump materials.
Flashcard 14: What is the main function of nervous tissue in organs?
Answer: Sends signals to control and coordinate body functions. Enables rapid communication between organ parts.
Flashcard 15: What is the main function of connective tissue in organs?
Answer: Supports, binds, and protects other tissues. Provides structural framework and cushioning.
Flashcard 16: Which option best describes why organs can perform complex functions?
Answer: Different tissues combine and coordinate specialized jobs. Multiple tissue types enable complex organ functions.
Flashcard 17: What is a tissue in multicellular organisms?
Answer: A group of similar cells working together to perform a function. Cells with the same structure unite for a common task.
Flashcard 18: Identify the main evidence that a structure is an organ rather than a tissue.
Answer: It contains different tissue types working together for one function. Organs combine tissues; tissues contain only one cell type.
Flashcard 19: Identify the tissue type: cells tightly packed, forming the skin surface and organ linings.
Answer: Epithelial tissue. Tight packing creates protective barriers.
Flashcard 20: Identify the best claim supported by this evidence: different tissues combine in one structure.
Answer: Cells form tissues, and multiple tissues together form an organ. Multiple tissues combining is the hallmark of organs.
Flashcard 21: Identify the main evidence that a structure is a tissue rather than a single cell.
Answer: It contains many similar cells organized to do one shared job. Tissues have multiple cells; single cells work alone.
Flashcard 22: Which statement best explains why muscle cells form muscle tissue?
Answer: Similar specialized cells group to perform the same movement function. Specialized cells unite when they share the same function.
Flashcard 23: What is cell differentiation?
Answer: The process by which cells become specialized in structure and function. Cells develop specific features for particular jobs.
Flashcard 24: What is an organ?
Answer: A structure made of multiple tissues working together for a function. Different tissue types combine for complex functions.
Flashcard 25: What is the correct order of biological organization from smallest to largest in this skill?
Answer: Cell e28692 tissue e28692 organ e28692 organ system e28692 organism. Each level contains and organizes the previous level.
Flashcard 26: What role do cell junctions play in forming tissues?
Answer: They connect neighboring cells so the group can act as a coordinated unit. Physical connections enable cells to work together.
Flashcard 27: Which tissue type carries signals quickly through the body?
Answer: Nervous tissue. Neurons transmit electrical impulses rapidly.
Flashcard 28: Which tissue type supports, connects, or protects body parts (for example, bone)?
Answer: Connective tissue. Provides structural framework and fills spaces.
Flashcard 29: Identify the best evidence that the heart is an organ rather than a tissue.
Answer: It contains muscle, connective, nervous, and epithelial tissues. Four tissue types prove organ-level organization.
Flashcard 30: Which tissue type provides the rapid signaling needed to coordinate organ activity?
Answer: Nervous tissue. Neurons transmit electrical signals quickly.
