1. Which plant tissue provides mechanical support and is flexible?
Solution
Correct: C
Collenchyma tissue has unevenly thickened cell walls, providing both strength and flexibility to plants, allowing them to bend without breaking.
2. Which type of connective tissue is characterized by the presence of lacunae?
Solution
Correct: D
Cartilage contains lacunae where chondrocytes (cartilage cells) are stored, distinguishing it from other connective tissues like bone or blood.
3. Which animal tissue is responsible for rapid transmission of stimuli?
Solution
Correct: B
Nervous tissue contains neurons that transmit electrical impulses for quick signaling and coordination of body functions.
4. Which plant tissue stores food in the form of starch and is loosely packed?
Solution
Correct: B
Parenchyma cells have thin cell walls and large intercellular spaces, making them ideal for storing food and nutrients.
5. Epithelial tissue is characterized by:
Solution
Correct: D
Epithelial tissues form protective layers and have tightly packed cells with minimal intercellular spaces to provide barriers.
6. Which tissue is responsible for the transport of minerals in plants?
Solution
Correct: A
Xylem is responsible for transporting water and minerals from roots to leaves, while phloem transports food.
7. The primary function of areolar connective tissue is:
Solution
Correct: C
Areolar tissue fills spaces between organs, providing support and cushioning while protecting organ movement.
8. Which muscle tissue is involuntary and found in internal organs?
Solution
Correct: B
Smooth muscle is non-striated and involuntary, controlling movements of internal organs like the stomach.
9. Which of these is a complex permanent tissue in plants?
Solution
Correct: C
Phloem consists of sieve tubes, companion cells, and other components, making it a complex tissue for food transport.
10. Bone differs from cartilage in that it:
Solution
Correct: B
Bone's hardness is due to calcium phosphate deposition, providing structural rigidity compared to cartilage.
11. Which of these is a type of meristematic tissue?
Solution
Correct: A
Apical meristems are located at root and shoot tips and are responsible for primary plant growth.
