What makes a living thing?
What do living things have that non living do not? • What do living things do that non living do not?
1. Living things are made of cells • Unicellular or single celled organisms • Multicellular organisms (made of many cells)
2. Living Things Take in Nutrients • Consumers - consume (eat) other organisms for food • Producers - produce their own food using energy from the Sun and nutrients from their surroundings
3. Living Things Use Energy • Living things use energy for life processes (growth, movement, sleep) • Consumers: get energy from the food they eat. • Producers: make their own food from the energy they take in. .
4. Living Things Produce Waste Eg. Carbon dioxide, urine, and feces. Plants oxygen Animals carbon dioxide. Consumers poop
4. Living Things Produce Waste Unicelluar organisms: Waste passes across the membrane of a cell into the environment, or is excreted by a vesicle Multicellular organisms: Have structures and systems that collect and remove waste. Humans have kidneys that filter waste from blood
5. Living Things Respond to Stimuli • Stimulus (plural: stimuli): anything that causes a living thing to respond in a certain way
5. Living Things Respond to Stimuli • Internal stimuli – occur inside a living thing’s body and cause a response • something you feel: hunger, thirst, love • ex stomach growling –> eat food, • External stimuli – occurs outside the body ( from the environment) to cause a response • Eg Light –> plant grows towards it, • Eg Heat (hot outside we sweat)

6. Living Things Grow • Unicellular organisms: grow by increasing in cell size up to a certain point. • Multicellular organisms: grow by increasing the number of cells in their body
7. Living Things Reproduce Unicellular Organisms reproduce by: • Cell division: eg. bacteria divide into two cells • Budding – eg. yeast cells pinch off a piece that grows into new cell
7. Living Things Reproduce Multicellular Organisms reproduce by mating:
