🌾 Key Points
→ Most of the monocotyledonous plants have bulky endosperm in their seeds.
→ Grains like maize have a special layer called the aleurone layer.
→ Aleurone layer: It is a proteinaceous layer of the endosperm that separates the embryo from the endosperm in plants like wheat, maize, and other grains.
→ The ploidy of aleurone is the same as that of the endosperm.
→ Ploidy refers to the number of sets of chromosomes in a cell.
→ Haploid: Refers to one set of chromosomes, denoted by (n).
→ Diploid: Refers to 2 sets of chromosomes, denoted by (2n).
→ Triploid: Has 3 sets of chromosomes, denoted by (3n).

🌺 Important Points
→ Double fertilization is a unique process in angiosperms.
→ Each pollen grain has 2 male gametes, both of which take part in fertilization.
→ Double fertilization involves 2 processes:
→ Syngamy: The fusion of one male gamete with the egg cell to produce a zygote, which later develops into an embryo.
→ Triple fusion: The fusion of the 2nd male gamete with the 2 polar nuclei of the embryo sac to produce the endosperm.
→ Explanation:
→ Syngamy: Male gamete (n) + Egg (n) → Zygote (2n)
→ Triple fusion: Male gamete (n) + 2 Polar nuclei (n) → Endosperm (3n)
→ Therefore, the endosperm is triploid in nature.
→ As the aleurone layer is a part of the endosperm, it is also triploid.

📝 Additional Information
→ Zygote: It is diploid as it is formed by the fusion of a haploid male gamete and a haploid female gamete.
→ Synergids: These are haploid cells of the embryo sac formed from the haploid megaspore by mitosis.
→ Antipodals: These are also haploid, as they are formed from the megaspore as part of the embryo sac.
