Answer:
1. Which of the following is not an asexual reproductive structure?
The correct answer is b) pollen. Pollen is a male reproductive structure produced by plants. It contains male gametes, which are involved in sexual reproduction.
Other options like zoospores, buds, and conidia are examples of asexual reproductive structures.
2. Parthenogenesis is the development of an organism directly from:
The correct answer is a) Female gametes. Parthenogenesis is a form of asexual reproduction in which an embryo develops from an unfertilized egg cell. It is a common reproductive strategy among invertebrates, such as insects and crustaceans, and some vertebrates, such as lizards and fish.
In parthenogenesis, the female gamete undergoes cell division and forms an embryo without fertilization by a male gamete. This process can occur naturally or be induced by artificial means.
Vegetative cells and fertilized ovum are not involved in parthenogenesis. Vegetative cells can give rise to new individual cells but not a whole organism, and fertilized ovum involves the fusion of a male and female gamete, which is not the case in parthenogenesis.
