Floral Morphology & Placentation — NEET Biology

NTA focuses on placentation, the arrangement of ovules inside the ovary, which directly affects fruit and seed development. Students often confuse the different types—axile, parietal, free-central, and marginal—and mix up their defining features. The key is to visualize the ovary's cross-section: where exactly are the ovules attached? Axile means along the central axis (most common in multilocular ovaries), while parietal means on the inner wall (in unilocular ovaries). Understanding placentation is critical because it determines fertility patterns and appears frequently in comparative plant anatomy questions. Memorize the visual diagrams and link each type to example plants.
