The pistil is the female reproductive organ of a flower, consisting of three main parts: the swollen bottom part is the ovary, the middle elongated part is the style, and the terminal sticky part is the stigma. The ovary contains tiny bead-like structures called ovules.
The pistil is the female reproductive organ of a flower, consisting of three main parts: the swollen bottom part is the ovary, the middle elongated part is the style, and the terminal sticky part is the stigma. The ovary contains tiny bead-like structures called ovules.
Think of the pistil like a fruit-producing factory: the stigma is the receiving dock at the top, the style is the delivery chute/hallway, the ovary is the main processing vault at the bottom, and the ovules are the raw seeds waiting to be manufactured into final products.
SOS - Stigma (Top), Style (Middle), Ovary (Bottom/Swollen).
Pistil=Stigma+Style+Ovary
Ovary\rightarrow Fruit,\quad Ovule\rightarrow Seed
During pollination, pollen grains land on the sticky stigma, germinate, and grow down through the style to reach the ovary. Inside the ovary, the male gamete fertilizes the ovule, which subsequently develops into a seed, while the ovary ripens into a fruit.
The pistil (or carpel) is the female reproductive unit of angiosperms.
Stigma acts as the landing platform for pollen grains.
Style connects the stigma to the ovary and supports pollen tube growth.
Ovary contains ovules which develop into seeds after fertilization.
Ensures protected fertilization inside the ovary.
Facilitates precise selection of compatible pollen grains on the stigma.
Sexual reproduction in flowering plants (Angiosperms).
Crop breeding and hybrid seed production.
A flower may have a single carpel (monocarpellary) or multiple carpels (multicarpellary).
When multiple carpels are fused together, the condition is syncarpous; when free, it is apocarpous.
A is correct тАФ (i) - (c), (ii) - (d), (iii) - (a), (iv) - (b) correctly match the parts of the pistil and their functions.
Remember that after fertilization, petals, sepals, and stamens usually wither and fall off, while the ovule transforms into a seed and the ovary wall thickens to form the pericarp of the fruit.
