Question 212 of 300
📘 CLASS XI
Match the inflorescence patterns with their growth dynamics:
Column I (Inflorescence Type)
Column II (Growth Behavior of Main Axis)
(a) Racemose
(i) Main axis terminates in a flower; limited in growth; basipetal order
(b) Cymose
(ii) Main axis continues to grow; flowers borne laterally in acropetal succession
(c) Solitary
(iii) Shoot tip transforms directly into a single flower
In racemose inflorescence, the main axis continues growing and flowers are borne laterally in acropetal succession. In cymose inflorescence, growth is limited as the main axis terminates in a flower, and flowers are in basipetal order. A solitary flower occurs when a shoot tip transforms directly into a single flower.
Question 213 of 300
📘 CLASS XI
Match the floral whorls with their primary description:
Column I (Floral Whorl)
Column II (Anatomical Description / Category)
(a) Calyx & Corolla
(i) Reproductive organs directly involved in sexual reproduction
(b) Androecium & Gynoecium
(ii) Accessory organs of the flower that are not directly reproductive
(c) Receptacle / Thalamus
(iii) Swollen end of the pedicel on which the floral whorls are arranged
Calyx and corolla are accessory organs, whereas androecium (male) and gynoecium (female) are reproductive organs. The thalamus or receptacle is the swollen end of the pedicel that bears these four whorls.
Question 214 of 300
📘 CLASS XI
Match the floral symmetry definitions with their technical names:
Column I (Symmetry Type)
Column II (Mathematical / Plane Division Criteria)
(a) Actinomorphic
(i) Irregular; cannot be divided into two similar halves in any vertical plane
(b) Zygomorphic
(ii) Radial symmetry; divisible into equal halves in any radial plane
(c) Asymmetric
(iii) Bilateral symmetry; divisible into similar halves only in one vertical plane
Actinomorphic flowers have radial symmetry and can be divided into equal halves in any radial plane passing through the center. Zygomorphic flowers have bilateral symmetry and are divisible into similar halves in only one particular vertical plane. Asymmetric (irregular) flowers cannot be divided into similar halves in any plane.
Question 215 of 300
📘 CLASS XI
Match the floral symmetry examples with their taxonomic representatives:
Column I (Symmetry Class)
Column II (Botanical Examples)
(a) Actinomorphic group
(i) Pea, Gulmohur, Bean, Cassia
(b) Zygomorphic group
(ii) Mustard, Datura, Chilli
(c) Asymmetric group
(iii) Canna
Actinomorphic examples in the text are mustard, datura, and chilli. Zygomorphic examples are pea, gulmohur, bean, and Cassia. Asymmetric example is canna.
Question 216 of 300
📘 CLASS XI
Match the terminology of flower parts and bracts with their definitions:
Column I (Bract / Appendage Term)
Column II (Structural Feature / Multiples)
(a) Bracteate
(i) Flowers without reduced leaves at the base of the pedicel
(b) Ebracteate
(ii) Flowers with reduced leaves (bracts) found at the base of the pedicel
(c) Trimerous, Tetramerous, Pentamerous
(iii) Floral appendages are in multiples of 3, 4, or 5 respectively
Flowers with reduced leaves called bracts at the base of their pedicel are bracteate, and those without are ebracteate. Flowers are trimerous, tetramerous, or pentamerous when appendages are in multiples of 3, 4, or 5 respectively.
Question 217 of 300
📘 CLASS XI
Match the positions of floral parts on the thalamus with their descriptions:
Column I (Flower Classification)
Column II (Relative Placement of Ovary and Whorls)
(a) Hypogynous flower
(i) Margin of thalamus grows upward, enclosing and fusing with ovary
(b) Perigynous flower
(ii) Gynoecium is central; other whorls are on thalamus rim at same level
(c) Epigynous flower
(iii) Gynoecium occupies the highest position; other parts are situated below
In hypogynous flowers, the gynoecium is at the highest point and other parts are below. In perigynous flowers, the gynoecium is central and other parts are on the rim at almost the same level. In epigynous flowers, the thalamus completely encloses and fuses with the ovary, and other parts arise above it.
Question 218 of 300
📘 CLASS XI
Match the ovary classifications with their diagnostic examples:
Column I (Ovary Status)
Column II (Botanical Representative Taxa)
(a) Superior ovary
(i) Plum, Rose, Peach
(b) Half inferior ovary
(ii) Mustard, China rose, Brinjal
(c) Inferior ovary
(iii) Guava, Cucumber, Ray florets of sunflower
Superior ovary (hypogynous) is found in mustard, china rose, and brinjal. Half inferior ovary (perigynous) is found in plum, rose, and peach. Inferior ovary (epigynous) is found in guava, cucumber, and ray florets of sunflower.
Question 219 of 300

(i) Gamopetalous
(b) Sepals free
(ii) Polysepalous
(c) Petals united
(iii) Gamosepalous
(d) Petals free
(iv) Polypetalous
Gamosepalous refers to united sepals. Polysepalous means free sepals. Gamopetalous refers to united petals. Polypetalous refers to free petals.
Question 220 of 300
📘 CLASS XI
Match the corolla shapes with their descriptions:
Column I (Corolla Shape)
Column II (Morphological Form)
(a) Tubular
(i) Shaped like a hollow cylinder or tube
(b) Bell-shaped
(ii) Shaped like a campanulate cup or bell
(c) Funnel-shaped
(iii) Shaped like an infundibuliform funnel
(d) Wheel-shaped
(iv) Shaped like a rotate wheel
The shape of the corolla varies greatly in angiosperms; tubular, bell-shaped, funnel-shaped, and wheel-shaped are major morphological variations mentioned in the textbook.
