Question

difference between double fertilization and syngamy? Related:  Fun Video: Double fertilization?

Answer

Fertilization and Syngamy both are two types of different reproduction processes. Syngamy refers to fusion of two cells and one nuclei, here triple fusion occur  so this is also known as triple fusion. where as fertilisation refers to the fusion of one male gamete (I.e., sperm) and female gamete(I.e, ovum)it is a diploid state of cells containing 2n cells.

Answer

Syngamy and fertilization are synonyms just the diffrerence between them is that syngamy is the process of fusion of two gametes to form zygote while fertilisation refers to the act or process of rendering fertile.

Answer

Difference Between Double Fertilization and Syngamy
Double fertilization and syngamy are two vital processes in plant reproduction, but they serve different functions.
Double Fertilization
- Involves two fertilization events occurring in the ovule.
- One sperm cell fuses with the egg cell to form a diploid zygote (syngamy).
- The second sperm cell fuses with two polar nuclei to form a triploid endosperm nucleus, which nourishes the developing embryo.
- This process is unique to angiosperms (flowering plants) and ensures efficient nutrient transfer to the embryo.
Syngamy
- Refers specifically to the fusion of the male sperm cell with the female egg cell.
- This results in the formation of a diploid zygote, marking the beginning of a new organism.
- Syngamy occurs in both plants and animals, making it a broader term than double fertilization.
Key Differences
- Occurrence: Double fertilization is exclusive to flowering plants, while syngamy occurs in both plants and animals.
- Outcome: Double fertilization produces both a zygote and an endosperm, whereas syngamy results solely in the zygote.
- Function: Double fertilization enhances seed viability and nutrition, while syngamy is essential for the initiation of development in the zygote.
In summary, while syngamy is a crucial part of double fertilization, the latter encompasses a more complex process necessary for the successful development of seeds in flowering plants. Understanding these processes is essential for grasping plant reproductive biology, especially in the context of NEET studies.
