Study Notes
- Biology is the study of life in all its aspects
Sub-Sciences of Biology
- Zoology deals with animals
- Botany deals with plants
Important Sciences in Biology
- Morphology is the study of external form
- Anatomy is the study of internal structure
- Physiology is the study of function
- Embryology is the study of development
- Taxonomy is the study of classification
- Ecology is the study of the relationship between organisms and their habitats
- Genetics and evolution are also important sciences
General characteristics of living organisms
- All living organisms are composed of protoplasm, referred to as living matter
- Protoplasm is a complex system with a constant interchange of materials between its components
- Growth results from nutrition, where substances are produced and used up in respiration
- Growth leads to an increase in the amount of protoplasm
- Respiration is a chemical reaction within cells that releases energy from food
- Sensitivity is the ability to detect changes in the surrounding environment
- Reproduction is the ability to produce offspring and pass genetic information
- Excretion is getting rid of waste
- The power of reproduction is common in all living organisms
- New individuals are formed that are similar to the previous generation
- Nutrition is the intake and use of nutrients, which occurs in different ways for different organisms
- Evolution is the ability of living organisms to adapt to their environment
- During evolution, changes occur in populations, leading to improved metabolism, response, and reproduction
- Organisms develop abilities to cope with their environment that their ancestors did not have
- Irritability and movement are exhibited by all living organisms, allowing them to respond to external stimuli
- In animals, movement is highly developed as a way to obtain food
- Metabolism distinguishes living organisms from non-living things
- It is the ability to show spontaneous activity and do work, obtaining energy
- Energy source in a living organism can be found in chemical compounds like carbohydrates and proteins
- Molecules contain energy that can be released by exothermic reactions, known as "respiration"
- Anabolism is a constructive process in metabolism
- Simple molecules combine to form complex molecules, requires energy
- Catabolism is a destructive process involving the breakdown of complex molecules into simpler ones
- Catabolism proceeds with the release of energy, acting as a driving force
- Catabolic reactions are catalyzed by enzymes
- Adaptation is any alteration in the structure or function of an organism
- Results from natural selection, allowing the organism to better survive and multiply in its environment
- A stimulus is a detectable change in the internal or external environment
- The ability to respond to external stimuli defines sensitivity
- Homeostasis is the ability to maintain a constant internal environment in response to environmental changes
- Homeostasis is a unifying principle of biology
- The nervous and endocrine systems control homeostasis through feedback mechanisms involving organs and organ systems
