Questions and Answers
What are the seven life processes in living organisms and give an example of each?
The seven life processes are nutrition, respiration, excretion, transportation, regulation, growth, and reproduction. Examples include photosynthesis for nutrition, breathing for respiration, and urination for excretion.
What is homeostasis and why is it important for living organisms?
Homeostasis is the ability of living organisms to maintain a stable internal environment despite changes in the external environment. It is important because changes in the internal environment can disrupt the normal functioning of cells and tissues.
Describe the process of cellular respiration, including its reactants and products.
Cellular respiration is the process by which cells convert glucose and oxygen into carbon dioxide, water, and energy. The reactants are glucose and oxygen, while the products are carbon dioxide, water, and ATP (energy).
Study Notes
Life Processes
- Seven life processes in living organisms: Movement, Sensitivity, Nutrition, Respiration, Excretion, Growth, and Reproduction
- Movement: Muscle contraction in humans, e.g., walking, running
- Sensitivity: Response to stimuli, e.g., plants bending towards light
- Nutrition: Ingestion, digestion, and absorption of nutrients, e.g., photosynthesis in plants
- Respiration: Breathing, e.g., oxygen intake and carbon dioxide release in humans
- Excretion: Removal of waste, e.g., sweating in humans
- Growth: Increase in size, e.g., development of cells, tissues, and organs in humans
- Reproduction: Production of offspring, e.g., fertilization in humans
Homeostasis
- Homeostasis: Maintenance of a stable internal environment despite external changes
- Importance: Enables living organisms to function optimally, respond to stimuli, and maintain health
Cellular Respiration
- Cellular respiration: Process of generating energy from glucose, releasing ATP (adenosine triphosphate)
- Reactants: Glucose, oxygen
- Products: ATP, carbon dioxide, water
- Process: Glycolysis, Citric Acid Cycle, Electron Transport Chain, and Oxidative Phosphorylation
