Anther:
- The anther is the male reproductive organ of a flower, responsible for producing and releasing pollen.
- It is typically located at the tip of the stamen, the male reproductive part of the flower.
- The anther is made up of four lobes, each containing pollen sacs where pollen grains are produced.
- The anther is supported by a filament, which connects it to the rest of the flower.

Pistil:
- The pistil is the female reproductive organ of a flower, responsible for receiving pollen and producing seeds.
- The pistil is typically located at the center of the flower and consists of three main parts: the stigma, style, and ovary.
- The stigma is the sticky, often bulbous tip of the pistil that receives pollen grains.
- The style is a slender tube that connects the stigma to the ovary.
- The ovary is the enlarged base of the pistil that contains ovules, which develop into seeds after fertilization.
- The pistil is surrounded by the stamens, the male reproductive organs of the flower.

Anther

- Filament: A stalk-like structure that supports the anther.
- Anther sac (locule): Two or four sacs within the anther where microspores (pollen grains) develop.
- Anther wall: The outer covering of the anther that protects the microspores.
- Pollen grains: Tiny, single-celled particles containing the male gametes (sperm).

Pistil

- Stigma: The topmost part of the pistil that receives pollen grains. It may be sticky or have hairs to aid in pollen capture.
- Style: A slender stalk that connects the stigma to the ovary.
- Ovary: The lower, swollen part of the pistil that contains the ovules (female gametes).
- Ovules: Small, sac-like structures within the ovary that each contain one female gamete (egg cell).
- Micropyle: A small aperture in the ovule through which the pollen tube enters during fertilization.
- Funicle: A stalk-like structure that attaches the ovule to the ovary.
- Integuments: Protective layers that surround the ovule (one or two in flowering plants).
