What term describes the mode of asexual reproduction in which offspring develop from unfertilized eggs?
a. Parthenogenesis
b. Budding
c. Regeneration
d. Fission

검증된 단계별 안내

Understand the concept of asexual reproduction: Asexual reproduction is a mode of reproduction that does not involve the fusion of gametes and results in offspring that are genetically identical to the parent.

Identify the term 'parthenogenesis': Parthenogenesis is a form of asexual reproduction where an organism develops from an unfertilized egg. This process occurs naturally in some plants, invertebrates, and vertebrates.

Differentiate between the options: Budding involves the growth of a new organism from a part of the parent, regeneration refers to the regrowth of lost parts, and fission is the division of a single organism into two or more separate entities.

Recognize that parthenogenesis is unique because it specifically involves the development of offspring from unfertilized eggs, without the need for fertilization.

Conclude that the correct term describing the mode of asexual reproduction where offspring develop from unfertilized eggs is 'parthenogenesis'.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Parthenogenesis

Parthenogenesis is a form of asexual reproduction where an organism develops from an unfertilized egg. This process allows for the generation of offspring without the need for fertilization by a male gamete, commonly seen in certain plants, invertebrates, and some vertebrates like reptiles and birds.

Asexual Reproduction

Asexual reproduction is a mode of reproduction that does not involve the fusion of gametes, resulting in offspring that are genetically identical to the parent. It includes various methods such as parthenogenesis, budding, regeneration, and fission, each with distinct mechanisms and occurring in different organisms.

Unfertilized Eggs

Unfertilized eggs are eggs that have not undergone fertilization by a sperm cell. In the context of parthenogenesis, these eggs can develop into a new organism without fertilization, bypassing the typical sexual reproduction process and leading to offspring that are clones of the parent.
