Study Notes
The Study of Biology
- Biology encompasses the study of all living organisms, including plants, animals, and microorganisms.
- Living things are found in diverse environments: land, water, and air.
- Biology aims to understand both existing organisms and those that have ever lived on Earth.
The Importance of Biology in Everyday Life
- Biology plays a crucial role in advancements related to food production and disease control.
- Plant and animal breeding has led to higher yields of food through the modification of organisms.
- Biological research contributes to better farming practices and methods for disease control, pests, and weeds.
Different Fields of Study in Biology
- Botany: Study of plants.
- Zoology: Study of animals.
- Microbiology: Study of microscopic organisms.
- Morphology: Examination of the forms and structures of organisms.
- Anatomy: Focus on gross internal structures.
- Histology: Study of microscopic structures within tissues.
- Cytology: Examination of cells.
- Physiology: Study of the living processes of organisms.
- Embryology: Investigation of early development stages of organisms.
- Palaeontology: Study of fossils and ancient life.
- Taxonomy: Classification of organisms.
- Ecology: Relationships between organisms and their environments.
- Biodiversity: Variety among living organisms.
- Evolution: The origins and changes in organisms over time.
- Genetics: Study of heredity and variations.
- Mycology: Study of fungi.
- Protistology: Study of protists.
- Phycology: Study of algae.
- Virology: Study of viruses.
- Bacteriology: Study of bacteria.
- Molecular Biology: Examination of molecules in organisms.
- Biotechnology: Application of living organisms in industrial processes.
- Bioinformatics: Use of information technology to analyze molecular biology data.
Characteristics of Living Things
- Cellular Structure: All living organisms consist of protoplasm forming cells, containing DNA that carries genetic information.
- Metabolism: Sum of biochemical processes, with anabolism building up substances and catabolism breaking them down for energy release and waste production.
- Growth: Increase in size and weight as organisms utilize food to develop structures.
- Movement: Visible in animals through locomotion; in plants, it occurs mainly within cells or in response to stimuli like light.
- Irritability: Living organisms respond to environmental stimuli (light, sound, temperature), demonstrating sensitivity and reaction.
-
Reproduction: Two types exist:
- Asexual Reproduction: Involves one parent organism producing new individuals from a part of itself.
- Sexual Reproduction: Involves the fusion of two parental sex cells, resulting in a new organism.
- Adaptability: Living organisms adjust to changes in their internal and external environments for survival.
