MCQ
Which of the following is a correct statement regarding animal tissues?
  • A. Epithelial tissues support organs structurally
  • B. Muscular tissues conduct nerve impulses
  • C. Neural tissues perform contraction
  • D. Connective tissues bind and support organs
✅ Correct Answer: D
Connective tissues: bind, support and connect different tissues/organs. Epithelial tissues: cover and protect surfaces. Muscular tissues: cause movement. Neural tissues: transmit electrical impulses.
MCQ
In multicellular animals, specific functions are carried out by:
  • A. One cell type only which handles all functions
  • B. Random group of cells put together for all functions
  • C. Groups of similar cells in a well-organised manner
  • D. Only tissues without organs
✅ Correct Answer: C
Multicellular animals have cell groups (tissues) performing specific roles in coordination.

MCQ
In animals, morphology includes study of:
  • A. External appearance of body parts
  • B. Cellular organelles and their arrangement
  • C. Internal appearance of body parts
  • D. Reproduction and its mechanism
✅ Correct Answer: A
Morphology in animals is defined as study of external features or forms.
MCQ
Assertion (A): Tissues are essential in multicellular organisms for specialised functions. Reason (R): Each cell in a multicellular organism performs all functions independently.
  • A. Both A and R are true and R is the correct explanation of A
  • B. Both A and R are true but R is not the correct explanation of A
  • C. A is true, R is false
  • D. A is false, R is true
✅ Correct Answer: C
Tissues play a central role in division of labour in multicellular organisms. They enable groups of similar cells to perform specific tasks efficiently. This structural organisation ensures better coordination and functionality. The reason (R) is incorrect because no single cell in a multicellular body performs all vital functions independently. Instead, functions are shared across tissues, organs, and systems.
MCQ
Identify the correct sequence in increasing order of complexity:
  • A. Cell → Organ → Tissue → Organ System
  • B. Organ → Cell → Tissue → Organ System
  • C. Cell → Tissue → Organ → Organ System
  • D. Tissue → Cell → Organ System → Organ
✅ Correct Answer: C
Cells form tissues. Tissues form organs. Organs function together to make organ systems. This sequence reflects increasing structural and functional complexity.
