Biology “BIO-”: Life “-OLOGY”: The study of Characteristics of life
1. All living things are: Made of Cells • CELL: Collection of living material enclosed within a barrier • -basic unit of life • Unicellular: made up of one cell • Multicellular: made up of many cells • Prokaryotic- NO nucleus • Eukaryotic- have a nucleus (and other membrane bound organelles) of Cells. Cheek cells
2. All living things are: Organized • Cells: basic unit of life • Tissues- made of cells • Organs- made up of tissues • Systems- group of organs
3. All living things have a genetic code (DNA) DNA- codes for all genes and proteins
Asexual • 4. AllLiving Things: Reproduce • asexual reproduction: has only one parent • sexual reproduction: requires two parents Sexual
5. All Living Things: Use & Need Energy!! AUTOTROPH: produce own food HETEROTROPH: must consume food Carnivores: meat-eaters Herbivores: plant-eaters Omnivore: eat plants & meat DECOMPOSER: breaks down dead material for food
6. All Living things: Change and have a lifespan GROWTH: increase in size and shape DEVELOPMENT: mature over time LIFESPAN: the length of time for which a person or animal lives or a thing functions Growth Development
7. All Living things adjust to their surroundings: Adjustment: short term change Stimulus: action/sound Reaction: response to a stimulus
