Study Notes
Characteristics of Living Organisms
- Movement: Ability of an organism or its parts to change position or place.
- Respiration: Series of chemical reactions breaking down nutrients in cells to release energy for metabolism.
- Sensitivity: Capability to detect and appropriately respond to internal and external stimuli.
- Growth: A permanent increase in size and mass due to either an increase in cell number or cell size, or both.
- Reproduction: Processes through which organisms produce more of their own kind.
- Excretion: Removal of toxic substances and waste products from metabolism.
- Nutrition: Intake of materials necessary for energy, growth, and development; plants require light, carbon dioxide, water, and ions, while animals consume organic compounds, ions, and water.
Exam Tip
- Use the mnemonic MRS.H.CIE to remember the characteristics of living organisms.
Classification of Organisms
- Organisms can be organized and classified based on their unique characteristics.
- Key subtopics include:
- Features of organisms
- Classifying animals
- Classifying plants
- Understanding viruses
- Using dichotomous keys for classification
Exam Questions Sample
- Identification of non-characteristics in living organisms (example: Photosynthesis is not seen in all living organisms).
- Features distinguishing dicotyledon plants, such as reticulated leaf veins and floral structures.
Important Definitions
- Dichotomous keys: Tools used to identify organisms based on a series of choices that lead to the correct identification.
