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.
