Angiosperm Ovule Structure — NEET Biology

Correct answer: D — A-IV, B-II, C-III, D-VI, E-V, F-I

This question tests the knowledge of the different parts of a typical angiosperm ovule and their correct descriptions, as provided in NCERT. - A. Funicle: NCERT states, 'The ovule is a small structure attached to the placenta by means of a stalk called funicle.' This matches with 'IV. The stalk that attaches the ovule to the placenta'. - B. Hilum: NCERT states, 'The body of the ovule fuses with funicle in the region called hilum. Thus, hilum represents the junction between ovule and funicle.' This matches with 'II. The junction between the ovule body and its stalk'. - C. Integuments: NCERT states, 'Each ovule has one or two protective envelopes called integuments.' This matches with 'III. Protective envelopes that encircle the nucellus'. - D. Micropyle: NCERT states, 'Integuments encircle the nucellus except at the tip where a small opening called the micropyle is organised.' It is the entry point for the pollen tube. This matches with 'VI. A small opening at the tip of the ovule, through which the pollen tube often enters'. - E. Nucellus: NCERT states, 'Enclosed within the integuments is a mass of cells called the nucellus. Cells of the nucellus have abundant reserve food materials.' This matches with 'V. A mass of cells enclosed within integuments, containing abundant reserve food materials'. - F. Chalaza: NCERT states, 'Opposite the micropylar end, is the chalaza, representing the basal part of the ovule.' This matches with 'I. Basal part of the ovule, typically opposite the micropyle'. Therefore, the correct match is A-IV, B-II, C-III, D-VI, E-V, F-I.
