FAQs on Living Things Grow and Develop Video Lecture - Crash Course for Class 6

1. What is the process of growth in living organisms?
Ans. Growth in living organisms refers to the increase in size and mass of an organism over time. This process involves cell division and expansion, where cells multiply and increase in size, leading to the overall growth of the organism. For instance, plants grow by adding new cells in their roots and stems, while animals grow by increasing the number of cells in their tissues.
2. How do living things develop throughout their life cycle?
Ans. Development in living things encompasses all the changes that occur from the beginning of life until maturity. This includes various stages such as infancy, childhood, adolescence, and adulthood in animals, or seed, germination, growth, flowering, and seed production in plants. Each stage is characterized by specific changes in structure and function, often influenced by genetic and environmental factors.
3. What is the difference between growth and development in living organisms?
Ans. Growth and development, while related, are distinct processes. Growth specifically refers to an increase in size and mass, while development encompasses the broader changes that occur throughout an organism's life cycle, including differentiation and maturation. For example, a caterpillar grows in size, but it undergoes development when it transforms into a butterfly, involving significant changes in form and function.
4. What factors influence the growth and development of living organisms?
Ans. Several factors influence growth and development, including genetics, environmental conditions, nutrition, and health. Genetic makeup determines the potential for growth, while environmental factors like temperature, light, and water availability play crucial roles. Adequate nutrition is essential for providing the energy and materials needed for growth, and overall health affects how well an organism can grow and develop.
5. Why is understanding growth and development important in biology?
Ans. Understanding growth and development is crucial in biology as it helps us comprehend how living organisms function and adapt throughout their lives. This knowledge is essential for various fields, including medicine, agriculture, and conservation. For instance, it enables scientists to develop better health care strategies for humans and animals, improve crop yields, and protect endangered species by understanding their life cycles and needs.
