Characteristics of Life
- Metabolism: the process by which cells generate energy and nutrients from food
- Catabolism: a type of metabolism that involves the breakdown of large substances into smaller ones
- Continuity of life: the idea that life is continuous and that all living organisms share a common ancestry
- Cell: the smallest entity that has all the characteristics of life
Organisation and Structure
- Organisation: the arrangement of components in a living organism to perform specific functions
- Organ system: a group of organs that work together to perform a specific function
- Organelles: structures within cells that perform specific functions
Reproduction
- Asexual reproduction: a type of reproduction that involves the production of offspring that are genetically identical to the parent, e.g. binary fission
- Sexual reproduction: a type of reproduction that involves the fusion of gametes from two parents to produce offspring with a unique combination of genetic traits
- Main difference between sexual and asexual reproduction: sexual reproduction produces offspring with genetic variation, while asexual reproduction produces offspring that are genetically identical to the parent
Nutrition and Excretion
- Nutrition: the process by which organisms obtain energy and nutrients from food
- Excretion: the process by which organisms remove waste products from their bodies, necessary for maintaining homeostasis and preventing toxicity
