Study Notes
Life Processes
- Life processes are necessary for sustaining ourselves and include nutrition, respiration, transportation, excretion, and reproduction.
Nutrition
- Nutrition is the process of obtaining essential substances for survival, growth, and reproduction.
- Organisms gather nutrients from plants, animals, and microorganisms.
- Nutrients include carbohydrates, proteins, fats, vitamins, minerals, and water.
Respiration
- Respiration generates energy using absorbed nutrients and eliminates waste products.
- There are two types of respiration: cellular and gas exchange respiration.
- Cellular respiration occurs inside cells, breaking down glucose to release energy.
- Gas exchange respiration occurs between body tissues and the external environment for oxygen uptake and carbon dioxide expulsion.
Transportation
- Transportation involves moving essential molecules, cells, and waste throughout the body to maintain homeostasis.
- Blood circulation delivers oxygen, nutrients, hormones, and heat.
- Cells possess structures like centrosomes and microtubules for intracellular movement of molecules and organelles.
Excretion
- Excretion removes waste products accumulated due to metabolic activities.
- Organ systems involved in excretion include kidneys, liver, gallbladder, skin, and lungs.
- Waste removal helps maintain normal physiological levels, preventing toxicity.
Reproduction
- Reproduction creates offspring genetically similar to their parents.
- Sexual reproduction combines genetic material from both parents, creating unique zygotes.
- Asexual reproduction involves one parent producing identical copies without meiosis or fertilization.
- Both methods serve to propagate species, passing traits and genes to future generations.
