Study Notes
Life Processes
- Movement: involves changing the position of the body to adapt to the environment, e.g., catching prey
- Reproduction: producing offspring to continue the species
- Sensitivity: sensing the environment through various means, such as touch, taste, sight, etc.
- Growth: increasing cell size and number, resulting in an organism getting bigger
- Respiration: breaking down glucose to produce energy
- Excretion: removing waste from the organism, e.g., carbon dioxide
- Nutrition: obtaining energy and nutrients, e.g., plants photosynthesizing, animals consuming other organisms
Living and Non-Living Things
- All organisms (bacteria, fungi, plants, and animals) on Earth are considered living things because they carry out the seven life processes (MRS GREN)
- Examples of living things exhibiting movement include plants growing towards light
- Viruses are non-living because they only carry out replication, which requires a host to copy themselves, and do not exhibit true reproduction
- Examples of non-living things include fire, clouds, and other entities that do not exhibit the seven life processes
