Study Notes
Life Processes
- Viruses are not considered alive because they do not exhibit any metabolic processes until they infect a cell.
- Diffusion is not efficient enough for oxygen transport in multicellular organisms because all cells might not be directly exposed to the environment.
- Nutrition is the process of obtaining nutrients from the external environment and transporting them into the body.
- Nutrients are essential for growth and development.
- Enzymes act as biological catalysts, breaking down complex food molecules into simpler substances for digestion.
- Autotrophic nutrition is the process where organisms synthesize their own food through photosynthesis.
- Examples of autotrophs include plants and blue-green algae.
- Photosynthesis involves the following key events:
- Absorption of light energy by chlorophyll
- Conversion of light energy into chemical energy
- Splitting of water molecules into hydrogen and oxygen
- Reduction of carbon dioxide to carbohydrates
