Nucellus III. Pore where integuments are absent D. Funicle IV. Parenchymatous mass enclosed within integuments Choose the correct answer from the options given below:
Options
- AA - III, B - II, C - I, D - IV
- BA - II, B - III, C - I, D - IV
- CA - II, B - III, C - IV, D - I
- DA - III, B - II, C - IV, D - I
Correct answer
C. A - II, B - III, C - IV, D - I
Step-by-step solution
The ovule is a small structure attached to the placenta by means of a stalk called the funicle. The integuments leave a small opening at the tip of the ovule called the micropyle. Opposite the micropylar end is the chalaza, representing the basal part of the ovule. Enclosed within the integuments is a mass of parenchymatous cells called the nucellus. Therefore, the correct matching is A - II, B - III, C - IV, D - I. Answer: A - II, B - III, C - IV, D - I
