Question
Placentation, in which ovules develop on the inner wall of the ovary or in peripheral part, is:
Free central
Basal
Axile
Parietal
, in parietal placentation, the ovules develop on the inner wall of the ovary or on the peripheral part. The ovary is initially one-chambered but becomes two-chambered due to the formation of a false septum (e.g., mustard and Argemone). In contrast, free central involves ovules on a central axis without septa, basal involves a single ovule at the base, and axile involves ovules attached to a central axis in a multilocular ovary .
This question aligns with the NEET BIOLOGY syllabus, specifically targeting concepts from Morphology of Flowering Plants. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.
