SECTION B – Assertion and Reasoning
Directions:
For questions 11–15, choose:
A. Both Assertion and Reason are true, and Reason is the correct explanation
B. Both are true, but Reason is NOT the correct explanation
C. Assertion is true, but Reason is false
D. Assertion is false, but Reason is true
- Assertion (A): Meristematic cells have dense cytoplasm and no vacuoles.
Reason (R): Meristematic cells actively divide and vacuoles would hinder cell division. - Assertion (A): Parenchyma stores food in plants.
Reason (R): Parenchyma cells have thin walls and large intercellular spaces enabling storage. - Assertion (A): Phloem transports water in plants.
Reason (R): Phloem contains sieve tubes and companion cells. - Assertion (A): Cardiac muscle fibres do not get fatigued.
Reason (R): Cardiac cells have many mitochondria and work continuously. - Assertion (A): Sclerenchyma cells are dead.
Reason (R): Their walls are thickened with lignin which blocks the lumen.
SECTION C – One-Word Answers
- Name the tissue that connects muscle to bone.
- Name the tissue with a fluid matrix.
- What is the living tissue that transports food in plants?

SECTION D – Short Answer Questions (30–50 words)
- What is meristematic tissue? Mention its types.
- Differentiate between apical and lateral meristem.
- What are the functions of stomata?
- Write any two differences between striated and smooth muscles.
- Why does the epidermis have a waxy coating of cutin in desert plants?
SECTION E – Short Answer Questions (50–70 words)
- Explain the structure and function of collenchyma tissue.
- Why are xylem and phloem called complex tissues?
- Describe the structure of a neuron with a labelled diagram (no need to draw here; describe only).
- What is the role of areolar tissue in the body?
- How does cork act as a protective tissue?
SECTION F – Long Answer Questions (80–120 words)
- Explain the differences between meristematic and permanent tissues in plants. Include structure, function, and location.
- Write a detailed note on epithelial tissues and their types. Give examples and functions of each.
- Describe the different connective tissues found in animals. Mention structure and functions of:
