, 1. MORPHOLOGY OF FLOWERING PLANTS
A flowering plant has root, stem, leaves, flowers, fruits and seeds. Root systems: tap root (dicot) and fibrous root
(monocot). Root modifications: storage (carrot), prop roots (banyan), stilt roots (maize), pneumatophores
(mangrove). Stem modifications: tuber (potato), rhizome (ginger), bulb (onion), runner, sucker, climbers. Leaf:
simple or compound; venation reticulate (dicot) or parallel (monocot). Flower: thalamus, calyx, corolla, androecium,
gynoecium. Placentation: marginal, axile, parietal, free central, basal. Fruit: true (from ovary) or false; fleshy or dry.
Seed: dicot (two cotyledons) or monocot (one cotyledon).
Q1. Prop roots are found in:
A. Maize
B. Banyan
C. Rhizophora
D. Carrot
✓ Correct Answer: B
Why this is correct: Prop roots (pillar-like roots growing downward from branches) are characteristic of banyan (Ficus
benghalensis).
✗ Why the other options are wrong:
• A has stilt roots.
• C has pneumatophores.
• D is a storage tap root.
Q2. Pneumatophores are:
A. Storage roots
B. Respiratory roots of mangroves
C. Climbing roots
D. Parasitic roots
✓ Correct Answer: B
Why this is correct: Pneumatophores are negatively geotropic roots of mangrove plants (e.g., Rhizophora) that help in
gaseous exchange in water-logged soil.
✗ Why the other options are wrong:
• A, C and D are different root modifications.
Q3. Potato is a modification of:
A. Root
B. Stem
C. Leaf
D. Flower
✓ Correct Answer: B
Why this is correct: Potato is a stem tuber – an underground stem modification that stores food and bears buds (‘eyes’).
✗ Why the other options are wrong:
• A would be sweet potato or carrot.
• C and D are incorrect.
Q4. Parallel venation is characteristic of:
A. Dicot leaves
B. Monocot leaves
C. All leaves
D. Only compound leaves
✓ Correct Answer: B
Why this is correct: Most monocot leaves show parallel venation, whereas dicot leaves usually show reticulate venation.
✗ Why the other options are wrong:
• A typically has reticulate venation.
NEET 2027 | High-Weightage Biology | Part 5 – Morphology to Mixed Practice Page 3
, • C and D are incorrect.
Q5. The arrangement of ovules inside the ovary is called:
A. Aestivation
B. Placentation
C. Phyllotaxy
D. Venation
✓ Correct Answer: B
Why this is correct: Placentation is the arrangement of ovules on the placenta inside the ovary (marginal, axile, parietal,
etc.).
✗ Why the other options are wrong:
• A is arrangement of petals/sepals in bud.
• C is arrangement of leaves on stem.
• D is arrangement of veins in leaf.
Q6. Axile placentation is found in:
A. Pea
B. Mustard
C. China rose / Tomato / Lemon
D. Sunflower
✓ Correct Answer: C
Why this is correct: In axile placentation the ovules are attached to a central axis in a multilocular ovary – seen in China
rose, tomato, lemon, etc.
✗ Why the other options are wrong:
• A has marginal.
• B has parietal.
• D has basal.
Q7. A flower that has both androecium and gynoecium is called:
A. Unisexual
B. Bisexual / Hermaphrodite
C. Incomplete
D. Staminate
✓ Correct Answer: B
Why this is correct: A bisexual (hermaphrodite) flower possesses both male (androecium) and female (gynoecium)
reproductive organs.
✗ Why the other options are wrong:
• A has only one.
• C lacks one or more floral whorls.
• D is a male flower.
Q8. The edible part of mango is:
A. Endocarp
B. Mesocarp
C. Epicarp
D. Seed
✓ Correct Answer: B
Why this is correct: In mango (a drupe) the fleshy edible portion is the mesocarp.
✗ Why the other options are wrong:
• A is the hard inner stone.
• C is the outer skin.
• D is not normally eaten.
