Study Notes
Characteristics of Life
- All living organisms are highly organized structures made up of one or more cells.
- Organisms respond to diverse stimuli, like bending toward light or moving towards or away from chemicals (chemotaxis) or light (phototaxis).
- Organisms reproduce by duplicating their DNA and dividing to form new cells.
- Multicellular organisms produce specialized reproductive cells.
- All living organisms exhibit adaptations to their environment.
- Organisms grow and develop according to instructions coded in their genes.
- Cells require specific conditions like appropriate temperature, pH, and chemical concentrations to function properly.
- All organisms have genetic material (DNA/RNA).
- Metabolism is the sum of all processes taking place inside an organism's body.
Cells
- The basic unit of life is a cell.
- Cells are organized into organelles, each with a specific function.
- There are different types of cells, including prokaryotic and eukaryotic cells.
Cell Diversity
- Cells vary in size, shape, and function, reflecting their roles in the organism.
Cell Membrane
- The cell membrane controls what enters and leaves the cell.
Cell Division
- Cell division allows organisms to grow, repair tissues, and reproduce.
- Mitosis is a type of cell division that produces two identical daughter cells.
- Meiosis is a type of cell division that produces four gametes (sex cells) with half the number of chromosomes.
Biological Molecules
- Carbs provide energy and structural support.
- Proteins are involved in various functions, including building structures, transporting substances, and catalysing reactions.
- Lipids store energy and form cell membranes.
- Nucleic acids carry genetic information.
Energy Processing
- Photosynthesis is the process by which plants use sunlight to convert carbon dioxide and water into glucose and oxygen.
