Q.16. Write the difference between cartilage and bone:
| Cartilage | Bone |
|---|---|
| Soft and flexible | Hard and inflexible |

Short Answer Questions (3 Marks)
Q.1. What is the utility of tissues in multicellular organisms?
Ans: In multicellular organisms, tissues enable the division of labor among different cell groups. Specific functions are performed by different types of tissues, allowing complex processes to occur efficiently. For example, the brain controls bodily functions, the heart pumps blood, kidneys filter waste, and sense organs gather information. This specialization is essential for the organism's survival and proper functioning.
Q.2. Give three features of cardiac muscles.
Ans: i. Cardiac muscles are involuntary and operate without conscious control.
ii. The cells are cylindrical, branched, striated, and uninucleate. iii. They contract and relax rhythmically.Q.3. What are the functions of areolar tissue?
Ans: Areolar tissue is a connective tissue that performs several functions, including:
i) Filling spaces inside organs. ii) Supporting internal organs. iii) Assisting in tissue repair.Q.4. Diagrammatically show the difference between the three types of muscle fibres.
Ans:
| Muscle Fibres | Visceral | Skeletal | Cardiac |
|---|---|---|---|
| Contracts | Slowly | Rapidly | Rapidly |
| Found | Viscera, Blood vessels | Trunk, Extremities, Head and neck | Heart |
| Control | Involuntary | Voluntary | Involuntary |
Q.5. Differentiate between striated, unstriated, and cardiac muscles on the basis of their structure and site/location in the body.
Ans:
| Feature | Striated Muscles | Unstriated Muscles | Cardiac Muscles |
|---|---|---|---|
| Striations | Light and dark bands present | No striations | Striations present |
| Cell Shape | Elongated, cylindrical, unbranched | Long, spindle-shaped, unbranched | Cylindrical and branched |
| Nuclei | Multinucleate | Uninucleate | Uninucleate |
| Function | Voluntary movements | Involuntary (walls of organs, vessels) | Involuntary (heart contractions) |
Q.6. How many types of tissues are found in animals? Name the different types.
Ans: Animals have four main types of tissues:
(a) Epithelial Tissue: Forms protective coverings. (b) Connective Tissue: Provides support and binds other tissues. (c) Muscular Tissue: Facilitates movement through contraction. (d) Nervous Tissue: Receives, processes, and transmits signals.Q.7. Differentiate between voluntary and involuntary muscles. Give one example of each.
Ans:
| Feature | Voluntary Muscles | Involuntary Muscles |
|---|---|---|
| Location | Attached to bones | Attached to visceral organs |
| Control | Move by conscious will | Function without conscious control |
| Cell Structure | Long, cylindrical, multinucleate | Uninucleate, often spindle-shaped |
| Example | Muscles in limbs | Heart muscle |
Q.8. What are the major functions of blood?
Ans: Blood is a connective tissue with several functions:
Transports oxygen, nutrients, hormones, and waste products. Regulates body temperature by distributing heat. Protects against disease via white blood cells and aids in wound healing. Contains platelets for blood clotting.Q.9. Write about the functions of:
(a) Epidermis: Provides protection and forms a waterproof barrier to reduce water loss. (b) Cork: Acts as a protective layer, preventing desiccation and injury while also blocking pathogens. (c) Stomata: Small openings on leaves that facilitate gas exchange.Q.10. Mention the characteristics features of connective tissue.
Ans: Connective tissue features include:
- Loosely spaced cells embedded in a non-living matrix.
- The matrix can be jelly-like, fluid, dense, or rigid.
- Its composition varies based on the specific function of the connective tissue.
