Study Notes
Introduction to Cells: Definition, Characteristics, Types, and Discovery
- A cell is the smallest unit of life responsible for all life processes and is present in all living beings.
- Cells are structurally, functionally, and biologically diverse and contain biomolecules and organelles suspended in cytoplasm.
- Cell biology is the study of cells from their basic structure to organelle functions.
- Robert Hooke discovered the cell in 1665, while Anton Van Leeuwenhoek observed cells with motility under a microscope.
- Prokaryotic cells lack a nucleus, while eukaryotic cells have a nucleus and membrane-bound organelles.
- All organisms are made up of cells, which can be unicellular or multicellular.
- Cells provide structure, convert nutrients into energy, and perform specialized functions.
- The nucleus holds genetic information necessary for reproduction and cell growth.
- Mitochondria generate energy, lysosomes digest waste, and endoplasmic reticulum synthesizes and processes molecules.
- Cells come in different shapes and sizes, and humans have more cells than bacteria.
- Cells are the lowest level of organization in every life form, and the count of cells varies from organism to organism.
- The discovery of cells helped us understand life processes and the structure and function of cells.
Introduction to Social Psychology and How Social Psychologists Work
- Psychology is the scientific study of behavior and mental processes.
- Psychology uses the same scientific process and methods as biology and chemistry.
- Psychology aims to understand why people engage in certain behaviors and how their brain controls their actions.
- Social relates to society or forming cooperative and interdependent relationships with others.
- Social psychology is the scientific study of behavior and mental processes as they relate to how people interact with others.
- Sociology is the study of society or groups, both large and small.
- Social psychology focuses on the individual as they relate to others and is affected by others.
- Personality psychology is the scientific study of individual differences in people’s thoughts, feelings, and behaviour, and how these come together as a whole.
- Social psychologists use observation as a method of studying behavior.
- Observations must be clearly defined and measured to be recorded accurately.
- Scientists seek to manipulate conditions to see the effect on social behavior.
- Experimentation is a hallmark of social psychology.
