A plant species exhibits cleistogamous flowers alongside chasmogamous flowers. What is the PRIMARY advantage conferred by the cleistogamous flowers?
Increased genetic diversity through cross-pollination
Assured seed set even in the absence of pollinators
Attraction of a wider range of pollinators
Production of larger and more nutritious seeds

In the flowers of a plant, the ovarian part is fused, but styles and stigmas are free. Its ovary becomes unilocular due to breakdown of partition wall and the ovules are attached to a central axis. Identify the plant.
Dianthus
Abutilon
Nymphaea
Michelia
Free-central placentation is found in
Citrus
Dianthus
Argemone
Brassica
How does parietal placentation differ from axile placentation in terms of ovule arrangement within the ovary?
Both have ovules attached to the central axis.
Parietal has ovules at the base, while axile has them on the wall.
Ovules attach to the peripheral wall in parietal, while they attach to the central axis in axile placentation.
There is no difference in ovule arrangement.
