Essay Questions
Construct detailed, essay-format answers for the following questions. (Answers not provided).
Describe the structure of a typical leaf in a flowering plant. Discuss its main parts, the two primary types of venation and their association with plant classification, and the three patterns of phyllotaxy.
Explain the concept of a flower as a modified shoot. Describe the four floral whorls of a typical flower, identifying the accessory and reproductive organs, and explain the significance of floral symmetry.
Provide a comprehensive overview of the female reproductive part of a flower, the gynoecium. Detail the structure of a carpel, the difference between apocarpous and syncarpous conditions, and describe the five main types of placentation.
Detail the characteristics of the Solanaceae family. Cover its vegetative characters (habit, stem, leaves) and floral characters (inflorescence, flower symmetry, calyx, corolla, androecium, gynoecium), and present its floral formula.
Trace the development of a flowering plant from seed to fruit. Differentiate between monocot and dicot seeds, explain how the plumule and radicle develop, and describe how ovary and ovules mature post-fertilization.
Glossary of Key Terms
A flower that can be divided into two equal radial halves in any radial plane (radial symmetry).
Roots that arise from parts of the plant other than the radicle.
The arrangement of sepals or petals in a floral bud with respect to other members of the same whorl.
The whorl composed of stamens, the male reproductive organs of a flower.
A condition where the carpels of a gynoecium are free (not fused).
A type where the placenta is axial and ovules are attached to it in a multilocular ovary.
The outermost whorl of a flower, composed of sepals.
Inflorescence where the main axis terminates in a flower, limiting growth; flowers are borne in basipetal order.
A one-seeded fruit with a pericarp differentiated into epicarp, mesocarp, and stony endocarp.
A food-storing tissue formed as a result of double fertilization in some seeds.
A flower where floral parts arise above the ovary, resulting in an inferior ovary.
A system where the primary root is replaced by many roots originating from the stem base (Monocots).
The female reproductive part of the flower, made up of one or more carpels.
A flower where the gynoecium occupies the highest position, resulting in a superior ovary.
The arrangement of flowers on the floral axis.
The region of the stem where leaves are borne.
The arrangement where veins run parallel to each other (Monocots).
A fruit formed without fertilization of the ovary.
The term used when the calyx and corolla are not distinct.
A flower where floral parts are on the rim of the thalamus at the same level as the ovary (half-inferior).
The pattern of arrangement of leaves on the stem or branch.
The arrangement of ovules within the ovary.
Roots modified to grow vertically upwards to get oxygen for respiration (found in swampy areas).
A swollen leaf base found in some leguminous plants.
Inflorescence where the main axis continues to grow and flowers are borne laterally in acropetal succession.
The arrangement where veinlets form a network in the lamina (Dicots).
A sterile stamen.
A condition where the carpels of a gynoecium are fused.
A system where the radicle elongation forms a primary root with lateral branches (Dicots).
The swollen end of the pedicel on which the whorls of a flower are arranged.
A flower that can be divided into similar halves only in one particular vertical plane (bilateral symmetry).
