Characterisitics of Living Things! What makes something living and nonliving? Sep 27 6:38 AM 1
All living things no matter how different from each other they may be share a set of common characteristics. Sep 27 6:43 AM 2
All Living organismshave the same 5 characteristics and 3 needs. This helps scientists classify things as living or non living. Does it eat? Does it grow? Does it interact? Does it move? Does it reproduce? Sep 23 9:04 AM 3
1. Characteristics of Living Things Living things are organized and made of cells cells: smallest unit of living matter > can be single celled (1 very simple and self sufficient cell) > can be multi celled (many different cells have different functions) example: blood cells, brain cells, skin cells,muscle cells, etc. Jan 12 12:41 PM 4
multi celled vs. single celled Jan 12 2:34 PM 5
2. Characteristics of Living Things Living things respond to stimuli > Stimulus: any change in an organism's surroundings that will cause the organism to react. Ex: change in light, background, temperature, space, water, food, or other organism > Response: an organism's reaction to stimulus. Ex: running away, color change, hiding in shell, growing thicker fur Stimulus comes first and response comes second Jan 12 12:41 PM 6
What's the stimulus and what is the response? Jan 12 3:07 PM 7
3. Characteristics of Living Things Living things obtain and use energy > Energy comes from food, oxygen, and water > Helps living things grow and develop Autotrophs: (plants) make their own food Heterotrops: (animals) get food from other plants and animals «Respiration: process where energy is released from food in most organisms Jan 12 12:41 PM 8
4. Characteristics of Living Things Living things grow and develop > Growth: process where organism becomes larger Ex: Getting taller > Development: organisms become more complex Ex: Getting smarter **Organism must have energy to grow and develop Jan 12 12:41 PM 9

PDF Characteristics of Living Things Notes.notebook 5. Characteristics of Living Things Living things reproduce > Reproduce: make offspring that have similar characteristics as the parents. 2 types: Sexual vs. Asexual Sexual: 2 parents (sperm and egg) combination of both parents traits Asexual: 1 parent identical offspring to parent Jan 12 12:41 PM 11
WHAT DO LIVING THINGS NEED? 1. Shelter 2. Water 3. Food Jan 12 12:45 PM 12
PDF Characteristics of Living Things Notes.notebook Scientists have categorized all living things into 5 kingdoms based on these characteristics. Plants Animals Fungi Protists 1 cell Bacteria/Monera 1 cell Jan 12 1:34 PM 13
Is it a living organism? 1. Is it made of cells? 2. Does it respond to stimuli? 3. Does it use energy? 4. Does it grow and develop? 5. Does it reproduce? Jan 12 2:24 PM 14
