In plants, after fertilisation the ovary develops into a ________.
Seed
Flower
Seedling
Fruit
Fruit
In angiosperms (flowering plants), fertilization marks the transformation of floral parts. Following successful fertilization, the ovary matures and undergoes physiological changes to develop into a fruit, while the ovules inside the ovary develop into seeds.
In angiosperms (flowering plants), fertilization marks the transformation of floral parts. Following successful fertilization, the ovary matures and undergoes physiological changes to develop into a fruit, while the ovules inside the ovary develop into seeds.
Think of the ovary as a 'nursery' that surrounds and protects the developing 'babies' (seeds) until they are ready, forming a 'cradle' known as the fruit.
O-F: Ovary to Fruit, O-S: Ovule to Seed (Remember 'OF-OS').
ZygoteтЖТEmbryo тАФ The developmental outcome of the egg cell after syngamy.
OvaryтЖТFruit тАФ The developmental outcome of the gynoecium after fertilization.
OvuleтЖТSeed тАФ The developmental outcome of the ovule after fertilization.
After fertilization, the zygote develops into an embryo, and the primary endosperm nucleus develops into endosperm. Simultaneously, the ovary wall (pericarp) thickens and differentiates into the fruit wall, protecting the developing seeds inside. The hormonal shift, particularly the rise in auxins and gibberellins, triggers this transition of the floral structure into a fruit.
The ovary wall becomes the fruit wall, scientifically termed the pericarp.
The process of fruit formation is often stimulated by the presence of developing seeds.
Flowers are essential for reproduction, but once their function is served, petals and sepals often wither.
Fruits provide protection for the developing seeds.
Fruits aid in seed dispersal by attracting animals or utilizing wind/water.
Agriculture: Understanding fruit development is crucial for crop yield management.
Botany: Taxonomic classification often relies on fruit types (e.g., fleshy vs. dry).
The entire process described is specific to angiosperms, where the seed is enclosed within a fruit.
Wrong options: Seed is the transformation of the ovule; Flower is the entire reproductive organ; Seedling is the young plant stage that develops after seed germination.
D is correct тАФ After fertilization, the ovary wall matures and ripens to become the fruit, which protects the seeds.
Always distinguish between the ovule (which becomes the seed) and the ovary (which becomes the fruit); this is a classic high-frequency question in competitive biology.
