Check the model questions with their explanations and answers here.
Questions | Options | Correct Answer | Explanation |
|---|---|---|---|
Which of the following is a plant hormone involved in seed dormancy? |
A. Auxin
B. Gibberellin C. Cytokinin D. Abscisic Acid | Abscisic Acid | Abscisic acid (ABA) is known as the stress hormone. It induces seed dormancy and helps the plant tolerate stress conditions. |
Triple fusion in angiosperms results in |
A. Zygote formation
B. Embryo formation C. Endosperm formation D. Seed coat development | Endosperm formation | Triple fusion involves fusion of a sperm nucleus with two polar nuclei to form a triploid endosperm. |
The primary function of the root cap is: |
A. Absorption of water
B. Protection of root meristem C. Anchorage D. Photosynthesis | Protection of root meristem | The root cap protects the delicate apical meristem as the root pushes through the soil. |
Which one of the following is a characteristic of dicotyledonous roots? |
A) Presence of pith
B) Polyarch vascular bundles C) Xylem and phloem arranged alternately D) Tetrarch to hexarch xylem bundles | Tetrarch to hexarch xylem bundles | In dicot roots, xylem is generally tetrarch (4) or hexarch (6), arranged in a radial manner with alternating phloem bundles. |
Which plant tissue is responsible for the transport of water? |
A. Phloem
B. Collenchyma C. Xylem D. Parenchyma | Xylem | Xylem conducts water and minerals from roots to aerial parts of the plant. |
Which of the following is a non-essential mineral element for plants? |
A. Zinc
B. Molybdenum C. Sodium D. Iron | Sodium | Sodium is not essential for most plants, though it may be beneficial for some C4 and CAM plants. |
Which stage of meiosis is responsible for the independent assortment of genes? |
A. Prophase I
B. Metaphase I C. Anaphase II D. Telophase I | Metaphase I | In metaphase I, homologous chromosomes align randomly, leading to independent assortment. |
In dicot stems, the vascular bundles are |
A. Scattered
B. Radial C. Conjoint, collateral and open D. Closed | Conjoint, collateral and open | Dicot stems have vascular bundles that are conjoint (xylem and phloem together), collateral (xylem and phloem side-by-side), and open (allowing secondary growth). |
The enzyme Rubisco is involved in |
A. Photorespiration
B. Light reactions C. Carbon fixation in Calvin cycle D. Water splitting | Carbon fixation in Calvin cycle | Rubisco catalyzes the fixation of CO₂ into a 5-carbon sugar during the Calvin cycle in photosynthesis. |
Which plant hormone is primarily responsible for fruit ripening? |
A) Auxin
B) Gibberellin C) Cytokinin D) Ethylene | Ethylene | Ethylene is a gaseous hormone involved in fruit ripening, senescence, and abscission in plants. |
The cork cambium originates from |
A. Epidermis
B. Cortex C. Phloem D. Pericycle | Cortex | Cork cambium (phellogen) usually arises from cortical cells during secondary growth |
Which of the following processes occurs in the grana of chloroplasts? |
A. Calvin cycle
B. Photorespiration C. Light-dependent reactions D. CO₂ fixation | Light-dependent reactions | The grana contain thylakoids where light-dependent reactions (photolysis and ATP/NADPH formation) occur. |
Which of the following plant hormones is responsible for cell elongation in plants? |
A) Cytokinin
B) Auxin C) Ethylene D) Abscisic acid | Auxin | Auxin promotes cell elongation, especially in shoot tips. It helps in plant growth and phototropism |
In C4 plants, the first stable product of carbon fixation is |
A. 3-phosphoglyceric acid
B. Oxaloacetic acid C. Malic acid D. Pyruvic acid | Oxaloacetic acid | In the C4 pathway, CO₂ is initially fixed into oxaloacetic acid (OAA) in mesophyll cells before entering the Calvin cycle. |
Transpiration is least in which of the following conditions? |
A) High temperature and low humidity
B) Low temperature and high humidity C) Windy and sunny D) Dry and hot | Low temperature and high humidity | Transpiration decreases when temperature is low and humidity is high because the water vapor gradient is reduced. |
The most abundant plant hormone is |
A. Cytokinin
B. Auxin C. Gibberellin D. Abscisic Acid | Auxin | Auxin (especially IAA) is the most abundant and well-studied plant hormone responsible for cell elongation and apical dominance. |
Which one of the following is a feature of meiosis but not mitosis? |
A) Equational division
B) Synapsis C) Chromosome duplication D) Spindle formation | Synapsis | Synapsis, the pairing of homologous chromosomes, occurs during prophase I of meiosis and not in mitosis |
Which structure in the plant is responsible for absorption of water and minerals? |
A) Stem
B) Root hair C) Xylem vessel D) Phloem | Root hair | Root hairs are extensions of root epidermal cells that increase surface area for water and mineral absorption. |
Double fertilization is characteristic of |
A) Gymnosperms
B) Angiosperms C) Bryophytes D) Pteridophytes | Angiosperms | In angiosperms, one male gamete fuses with the egg (syngamy), and another with the central cell (triple fusion), known as double fertilization. |
Which of the following is NOT a feature of dicotyledonous leaves? |
A) Reticulate venation
B) Stomata mostly on lower surface C) Parallel venation D) Presence of palisade mesophyll | Parallel venation | Parallel venation is typical in monocots; dicots usually have reticulate (net-like) venation. |
Which plant tissue is responsible for secondary growth in dicots? |
A) Apical meristem
B) Intercalary meristem C) Vascular cambium D) Xylem | Vascular cambium | Vascular cambium is a lateral meristem responsible for secondary growth, increasing girth in dicot stems and roots. |
Which part of the embryo in a seed gives rise to the shoot system? |
A) Plumule
B) Radicle C) Cotyledon D) Hypocotyl | Plumule | Plumule is the embryonic shoot and will develop into the shoot system after germination. |
Which of the following tissues is dead at maturity and provides mechanical support? |
A) Parenchyma
B) Collenchyma C) Sclerenchyma D) Xylem parenchyma | Sclerenchyma | Sclerenchyma is composed of dead cells with thick lignified walls that provide structural support. |
Which of the following is not a component of the phloem? |
A) Sieve tubes
B) Companion cells C) Tracheids D) Phloem parenchyma | Tracheids | Tracheids are part of the xylem, not phloem. Phloem consists of sieve tubes, companion cells, phloem parenchyma, and phloem fibers. |
