Question

Production of seeds without fertilization is known as:

• A. Parthenogenesis
• B. Apomixis
• C. Polyembryony
• D. Syngamy

Answer 1

The Correct Option is B

In the context of biology, when seeds are produced without fertilization, the process is termed "apomixis." This is distinct from sexual reproduction as it involves no fusion of gametes. Here's a breakdown of the terms to clarify: 

• Parthenogenesis: Involves development of an embryo from an unfertilized egg but generally does not produce seeds.
• Apomixis: Specifically refers to the formation of seeds without fertilization, bypassing the usual sexual reproduction process.
• Polyembryony: Refers to the development of multiple embryos from a single fertilized egg, not directly related to seed formation without fertilization.
• Syngamy: The fusion of two gametes during sexual reproduction, leading to fertilization.

Thus, apomixis is the correct term for seed production without fertilization.

Answer 2

The question asks about the process of production of seeds without fertilization. The correct term for this process is Apomixis.

Apomixis (Option 2) is the process in which seeds are produced without fertilization, meaning that the seeds are formed asexually, and the offspring are genetically identical to the parent plant. This occurs naturally in certain plant species.

Here’s a breakdown of the other options:

Parthenogenesis (Option 1): This term refers to the process of reproduction without fertilization, but it primarily applies to animals, not plants. In parthenogenesis, offspring are produced from an unfertilized egg.

Polyembryony (Option 3): This refers to the development of more than one embryo from a single fertilized egg. While it involves multiple embryos from one seed, it still requires fertilization.

Syngamy (Option 4): This term refers to the process of fertilization, where male and female gametes combine to form a zygote.

Thus, the correct answer is Apomixis (Option 2), which refers to the formation of seeds without fertilization.
