JKBOSE Class 12th Important Biology Textual Questions
What is the reproductive system of flowering plants?
Answer: Flowering plants have a complex reproductive system that involves both sexual and asexual reproduction. They possess specialized structures such as flowers, stamens, pistils and ovaries for reproduction.
How does pollination occur in flowering plants?
Answer: Pollination is the transfer of pollen from the anther to the stigma. It can occur through various agents like wind, water or animals. This process facilitates the fertilization of the ovule.
What happens after fertilization in flowering plants?
Answer: After fertilization the ovule develops into a seed and the ovary develops into a fruit. This allows for the dispersal of seeds and the continuation of the plants life cycle.
What are genes and their role in genetics?
Answer: Genes are segments of DNA that contain instructions for building and maintaining an organism. They carry genetic information that is passed from one generation to the next. Genes determine traits and play a crucial role in heredity and variation.
How does biology contribute to human welfare?
Answer: Biology plays a vital role in human welfare and the improvement of human health. It helps in understanding the structure, function and physiology of the human body, leading to the diagnosis and treatment of diseases. Additionally, advancements in biotechnology have led to medical breakthroughs such as vaccines, antibiotics and organ transplants, which have significantly improved human health and increased life expectancy.
