Which of the following citrus is monoembryonic (develops only one embryo per seed)?

✅Explanation:
-Pumelo (Citrus grandis) and Citron (Citrus medica) are the correct answers. These citrus varieties are monoembryonic, meaning each seed typically develops only one embryo.

• As explained before:
-Monoembryonic: In this type of citrus, a single fertilized egg (embryo) matures inside a seed.
-Polyembryonic: Most citrus varieties are polyembryonic. In these varieties, a seed can develop multiple embryos, with one arising from sexual reproduction and others from asexual reproduction within the ovule.

IMP 🔑Key Points:
Polyembryonic refers to the development of many embryos. When two or more two embryos develop from a single fertilized egg, then this phenomenon is known as Polyembryony.

• According to Webber, polyembryony is classified into three different types :
-Cleavage Polyembryony: In the case of this type, a single fertilized egg gives rise to a number of embryos.
-Simple polyembryony: In this type, a number of embryos develop as a result of the fertilization of several archegonia.
-Rosette polyembryony: Additional embryos develop from the rosette cells in certain gymnosperms, this type of polyembryony is termed rosette polyembryony.

🛑 Related Terminology:
-Embryo: The early stage of development of a seed or fertilized egg.
-Ovule: The structure in a flowering plant that contains the female reproductive cell and develops into a seed after fertilization.
