Biology for Grade 9 FAQs

1. What is biology?
Ans. Biology is the study of living organisms, including their structure, function, growth, evolution, and distribution.
2. What are the main branches of biology?
Ans. The main branches of biology include botany (study of plants), zoology (study of animals), microbiology (study of microorganisms), genetics (study of heredity), and ecology (study of organisms and their environment).
3. What is the importance of biology?
Ans. Biology is important because it helps us understand the natural world, including how living organisms function, interact, and evolve. It also plays a crucial role in fields such as medicine, agriculture, and conservation.
4. What is the scientific method in biology?
Ans. The scientific method in biology is a systematic approach used to investigate and understand natural phenomena. It involves making observations, formulating hypotheses, conducting experiments, analyzing data, and drawing conclusions.
5. What is the difference between prokaryotic and eukaryotic cells?
Ans. Prokaryotic cells are simpler and do not have a nucleus, while eukaryotic cells are more complex and have a nucleus. Prokaryotic cells include bacteria, while eukaryotic cells are found in plants, animals, fungi, and protists.
6. What is DNA and its role in biology?
Ans. DNA (deoxyribonucleic acid) is a molecule that carries the genetic instructions for the development, functioning, growth, and reproduction of all known organisms. It plays a crucial role in genetics and inheritance.
7. What is natural selection?
Ans. Natural selection is the process by which certain traits or characteristics become more or less common in a population over time, based on their ability to survive and reproduce. It is a key mechanism of evolution.
8. What is photosynthesis?
Ans. Photosynthesis is the process by which green plants, algae, and some bacteria convert sunlight, carbon dioxide, and water into glucose (a form of sugar) and oxygen. It is the primary source of energy for most living organisms.
9. What is the difference between mitosis and meiosis?
Ans. Mitosis is the process of cell division in which a single cell divides into two identical daughter cells, each with the same number of chromosomes as the parent cell. Meiosis, on the other hand, is a specialized form of cell division that produces gametes (sex cells) with half the number of chromosomes.
10. What is the role of enzymes in biology?
Ans. Enzymes are proteins that act as catalysts in biological reactions. They speed up chemical reactions in cells by lowering the activation energy required for the reaction to occur. Without enzymes, many essential biological processes would not be possible.
11. What is the difference between aerobic and anaerobic respiration?
Ans. Aerobic respiration is a process that occurs in the presence of oxygen and produces a large amount of energy (ATP) by breaking down glucose. Anaerobic respiration, on the other hand, occurs in the absence of oxygen and produces less energy through the incomplete breakdown of glucose.
12. What is the role of hormones in the human body?
Ans. Hormones are chemical messengers that regulate various physiological processes in the human body. They are produced by endocrine glands and help control growth, metabolism, reproduction, and other functions.
13. What is the difference between dominant and recessive traits?
Ans. Dominant traits are those that are expressed or visible in an organism's phenotype even if only one copy of the gene is present. Recessive traits, on the other hand, require two copies of the gene to be expressed.
14. What is the role of the immune system in the body?
Ans. The immune system is responsible for defending the body against harmful pathogens such as bacteria, viruses, and parasites. It consists of various cells, tissues, and organs that work together to identify and eliminate foreign substances.
15. What is the impact of human activities on the environment?
Ans. Human activities such as deforestation, pollution, overfishing, and climate change have a significant impact on the environment. These activities can lead to habitat destruction, loss of biodiversity, and other ecological problems.
