उत्तर
- Many times, calyx and corolla remain undifferentiated. Such member is known as tepal.
- The whorl of tepals is known as Perianth.
- It protects other floral whorls.
- If all the tepals are free the condition is called as polyphyllous and if they are fused the condition is called as gamophyllous.
- Sepaloid perianth shows green tepals, while petaloid perianth shows brightly coloured tepals. e.g. Lily, Amaranthus, Celosia, etc.
- Petaloid tepal helps in pollination and sepaloid tepals can perform photosynthesis.
