can u name a plant in which sepals remain attached after fertilization?
What you have asked is about persistent calyx. Normally after fertilization members of accesory whorls calyx and corolla wither off. Also necessory whorls too lose the spent parts like style, stigma, anther, filament and connective. Only ovary, ovules (and thalamus too sometimes as in Apple) plays role in forming fruit. However when sepals persists and remains attached to fruits too then it is called persistent calyx. Examples are Brinjal, Chilli, Tomatoes etc.
Meiosis is also known as reduction division in which the chromosome number is reduced to half in organisms which are diploid in nature. The haploid organism usually undergoes mitosis division to form diploid zygote. The zygote then undergoes meiosis division to form the embryo.
The noticeable difference between parthenocarpy and pathenogenesis is that parthenocarpy takes place in plants while parthenogenesis takes place in animals mostly in insects and lizards e.g- honeybee. Parthenocarpy is the production of fruits from unfertilized ovules in plants while parthenogenesis is the development of egg without fertilisation. Moreover fruits formed by Parthenocarpy do not contain seeds.
