- A. Mucocytes
- B. Leucocytes
- C. Oenocytes
- D. Granulocytes
Explanation: In cockroaches, oenocytes are specialised cells associated with producing lipids and waxes that contribute to the waterproofing of the…
Correct answer: Oenocytes- A. Epidermis
- B. Trichogen cell
- C. Basement membrane
- D. Malpighian cell
Explanation: A cockroach bristle develops from a specialised epidermal hair-forming cell called a trichogen cell.
Correct answer: Trichogen cell- A. Epicuticle
- B. Exocuticle
- C. Endocuticle
- D. All of these
Explanation: Melanin is deposited mainly in the pigmented exocuticle, the harder layer beneath the epicuticle, giving the cockroach cuticle its dark…
Correct answer: Exocuticle- A. Epicuticle
- B. Exocuticle
- C. Endocuticle
- D. All of these
Explanation: The epicuticle is the outermost thin, waxy layer of the cockroach cuticle and lacks chitin; its lipids help reduce water loss.
Correct answer: Epicuticle- A. Arthropods
- B. Chordata
- C. Annelida
- D. Echinodermata
Explanation: In many arthropods, the body is divided into head, thorax and abdomen, especially in insects.
Correct answer: Arthropods- A. Endodermis
- B. Mesophyll
- C. Chitin
- D. Epidermis
Explanation: The chitinous cuticle of an arthropod is secreted by the underlying epidermal cells.
Correct answer: Epidermis- A. Ligule
- B. Radula
- C. Mantle
- D. Muscle
Explanation: The radula is a rasping, tongue-like ribbon bearing many horny teeth, used by most molluscs to scrape or cut food.
Correct answer: Radula- A. Cephalopodsxc
- B. Gastropods
- C. Bivalves
- D. Athropods
Explanation: Snails are gastropod molluscs, a group characterised by a distinct head, muscular foot and usually a single coiled shell.
Correct answer: Gastropods- A. Placenta
- B. Notochord
- C. Cranianta
- D. Ligule
Explanation: The notochord is a flexible supporting rod lying along the mid-dorsal side of chordate embryos and is surrounded by connective tissue.
Correct answer: Notochord- A. 25,000
- B. 50,000

Correct answer: 50,000- A. Pisces
- B. Craniata
- C. Aves
- D. Amphibia
Explanation: Vertebrates are also called Craniata because they possess a cranium surrounding the brain.
Correct answer: Craniata- A. Frogs
- B. Reptiles
- C. Amphibinas
- D. Jawless fishes
Explanation: Jawless fishes, such as lampreys and hagfishes, retain primitive vertebrate features and lack jaws.
Correct answer: Jawless fishes- A. Cartilaginous fishes
- B. Bony fishes
- C. Running fishes
- D. Jawless fishes
Explanation: Scoliodon, or dogfish, has a skeleton made mainly of cartilage, so it belongs to the cartilaginous fishes.
Correct answer: Cartilaginous fishes- A. Primary Xylem and secondary xylem.
- B. Primary xylem and secondary phloem.
- C. Primary xylem and primary phloem
- D. Secondary xylem and secondary phloem.
Explanation: In a young dicot stem, vascular cambium first develops from dividing cells between the primary xylem and primary phloem, forming a cambium…
Correct answer: Primary xylem and primary phloem- A. Cork cambium
- B. Pith.
- C. Vascular cambium.
- D. Both a and c
Explanation: Secondary growth increases stem or root girth through the vascular cambium, which forms secondary xylem and phloem, and the cork cambium…

- B. Sclereids
- C. Trachea
- D. Collenchyma cells
Explanation: Tracheids are long, narrow, lignified cells that provide both support and water conduction, and they are generally more elongated than…
Correct answer: Tracheids- A. Cellulose.
- B. Peptidoglycan and murein.
- C. Lignin.
- D. Pectin.
Explanation: Sclerenchyma cells have thick secondary walls impregnated with lignin, making them hard and mechanically strong after maturity.
