Sexual reproduction is a process in which two parents contribute genetic material to produce offspring with genetic diversity.
Explain the process of pollination in plants.
Pollination is the transfer of pollen from the anther to the stigma of a flower, enabling fertilization and seed production.
What are the male and female reproductive organs in humans?
The male reproductive organs are testes, while the female reproductive organs are ovaries.
What is asexual reproduction?
Asexual reproduction is a type of reproduction that involves only one parent. The offspring are genetically identical to the parent.
Describe the process of fertilization in animals.
Fertilization is the fusion of sperm and egg to form a zygote, which then develops into an embryo.
What is the function of the ovule in plants?
The ovule contains the female reproductive cell, known as the egg or ovum, which is fertilized by pollen during pollination.
What is the purpose of meiosis in sexual reproduction?
Meiosis is a specialized cell division process that reduces the chromosome number by half, ensuring genetic diversity in offspring.
How do plants reproduce asexually?
Plants can reproduce asexually through methods such as vegetative propagation, fragmentation, and budding.
What are the advantages of sexual reproduction?
Sexual reproduction leads to genetic variation, which enhances the adaptability and survival of a species in changing environments.
Explain the role of mitosis in plant growth and development.
Mitosis is a cell division process that allows plants to grow, repair damaged tissues, and produce new cells for reproduction.
What is the role of the placenta during pregnancy?
The placenta is an organ that provides oxygen, nutrients, and waste elimination for the developing fetus in the uterus.
How does external fertilization occur in aquatic animals?
In aquatic animals, such as fish and frogs, external fertilization occurs when eggs and sperm are released into the water and combine outside the body.
What is the purpose of the stigma in a flower?
The stigma is a sticky structure that receives pollen during pollination and allows for the fertilization of the flower's ovules.
Discuss the advantages and disadvantages of asexual reproduction.
Advantages of asexual reproduction include rapid reproduction and the ability to colonize new environments. Disadvantages include lack of genetic diversity and vulnerability to environmental changes.
What is the purpose of the epididymis in the male reproductive system?
The epididymis is a coiled tube where sperm mature and are stored before being ejaculated during sexual reproduction.
How is seed dispersal important for plant reproduction?
Seed dispersal allows plants to colonize new areas, reduce competition with parent plants, and increase the chances of successful germination.
