Bsc 2nd year Botany 2nd paper important MCQ’s
1. The primary pigment involved in photosynthesis is:
- A) Chlorophyll b
- B) Carotene
- C) Chlorophyll a
- D) Xanthophyll
Answer: C) Chlorophyll a
Explanation: Chlorophyll a is the primary photosynthetic pigment responsible for capturing light energy and initiating the photosynthesis process.
2. Kranz anatomy is a characteristic feature of:
- A) C₃ plants
- B) C₄ plants
- C) CAM plants
- D) Algae
Answer: B) C₄ plants
Explanation: C₄ plants like maize and sugarcane exhibit Kranz anatomy, where bundle sheath cells are specialized for the Calvin cycle.
3. The plant hormone responsible for seed dormancy is:
- A) Auxin
- B) Gibberellin
- C) Abscisic acid
- D) Cytokinin
Answer: C) Abscisic acid
Explanation: Abscisic acid (ABA) induces and maintains seed dormancy by inhibiting growth and metabolic activities.
4. Which is a non-vascular plant group?
- A) Bryophytes
- B) Pteridophytes
- C) Gymnosperms
- D) Angiosperms
Answer: A) Bryophytes
Explanation: Bryophytes lack vascular tissues (xylem and phloem) and are considered non-vascular plants.
5. During glycolysis, glucose is converted into:
- A) Pyruvate
- B) Acetyl-CoA
- C) Ethanol
- D) Lactic acid
Answer: A) Pyruvate
Explanation: Glycolysis is the metabolic pathway that breaks down glucose into two molecules of pyruvate, producing ATP and NADH.
6. Which enzyme is crucial for CO₂ fixation in the Calvin cycle?
- A) RuBisCO
- B) ATP synthase
- C) Hexokinase
- D) PEP carboxylase
Answer: A) RuBisCO
Explanation: RuBisCO (Ribulose-1,5-bisphosphate carboxylase/oxygenase) is the key enzyme in the Calvin cycle, fixing CO₂ into organic molecules.
7. The functional unit of the chloroplast is:
- A) Cristae
- B) Grana
- C) Stroma
- D) Thylakoid
Answer: D) Thylakoid
Explanation: Thylakoids are the structural and functional units of chloroplasts where light-dependent reactions occur.
8. Which of the following is an example of a xerophyte?
- A) Hydrilla
- B) Cactus
- C) Mango
- D) Lotus
Answer: B) Cactus
Explanation: Xerophytes, like cacti, are adapted to arid environments with modifications like spines and thick cuticles to minimize water loss.
9. Double fertilization is unique to:
- A) Algae
- B) Bryophytes
- C) Gymnosperms
- D) Angiosperms
Answer: D) Angiosperms
Explanation: Double fertilization, where one sperm fertilizes the egg and the other fuses with polar nuclei to form the endosperm, occurs only in angiosperms.
10. Which of the following is a nitrogen-fixing cyanobacterium?
- A) Nostoc
- B) Spirogyra
- C) Chlamydomonas
- D) Ulva
Answer: A) Nostoc
Explanation: Nostoc is a cyanobacterium capable of fixing atmospheric nitrogen, converting it into forms usable by plants.
11. The main food storage in fungi is:
- A) Glycogen
- B) Starch
- C) Cellulose
- D) Fructose
Answer: A) Glycogen
Explanation: Fungi store carbohydrates as glycogen, similar to animals, rather than starch like plants.
12. Which of the following structures is haploid in the plant life cycle?
- A) Sporophyte
- B) Zygote
- C) Gametophyte
- D) Seed
Answer: C) Gametophyte
Explanation: Gametophytes are the haploid stage in the alternation of generations, producing gametes by mitosis.
13. The enzyme that breaks down cellulose is:
- A) Amylase
- B) Cellulase
- C) Lipase
- D) Protease
Answer: B) Cellulase
Explanation: Cellulase breaks down cellulose into glucose, aiding in the digestion of plant cell walls.
14. Which gas is released during photosynthesis?
- A) Carbon dioxide
- B) Oxygen
- C) Nitrogen
- D) Methane
Answer: B) Oxygen
Explanation: Oxygen is released as a by-product of photosynthesis during the splitting of water molecules in the light-dependent reactions.
15. Which plant tissue is responsible for the transport of water?
- A) Phloem
- B) Xylem
- C) Parenchyma
- D) Collenchyma
Answer: B) Xylem
Explanation: Xylem is the vascular tissue responsible for the upward transport of water and minerals from roots to other parts of the plant.
