Name the floral parts of an angiosperm and also mention their arrangements?

The floral parts of an angiosperm are:

1. Sepals: The outermost whorl of floral parts, usually green in color, and protect the flower bud. They are arranged in a whorl at the base of the flower.

2. Petals: The second whorl of floral parts, usually brightly colored and fragrant, attract pollinators. They are arranged in a whorl inside the sepals.

3. Stamens: The male reproductive organs of the flower, consisting of anthers (where pollen is produced) and filaments. They are arranged in a whorl inside the petals.

4. Carpels: The female reproductive organs of the flower, consisting of the stigma (where pollen is received), style (connects the stigma to the ovary), and ovary (contains ovules). They are arranged in the center of the flower.

The arrangement of these floral parts can vary depending on the species of angiosperm, but they are typically arranged in concentric whorls around a central axis.

Floral Parts of an Angiosperm

1. Calyx
- Arrangement: Outermost whorl of flower, composed of sepals
- Function: Protection of inner floral structures

2. Corolla
- Arrangement: Next whorl, composed of petals
- Function: Attraction of pollinators

3. Androecium (male reproductive organs)
- Stamens:
- Arrangement: One or more whorls
- Function: Production of pollen grains
- Filaments:
- Arrangement: Supports the anthers
- Anthers:
- Arrangement: Sacs containing pollen grains

4. Gynoecium (female reproductive organs)
- Pistil:
- Arrangement: Central part of flower
- Function: Production and protection of ovules
- Stigma:
- Arrangement: Top part of the style
- Function: Receives pollen grains
- Style:
- Arrangement: Connects the stigma to the ovary
- Ovary:
- Arrangement: Enlarged basal part
- Function: Contains the ovules
