The Characteristics of Living things
Basic unit structure in a functioning organism.
Organisms are made of one cell or many.
Unicellular organisms are made of one cell.
Multi-cellular organisms are made of more than one cell.
The Chemicals of Life
All living things are made up of chemicals.
The most of a material in a cell is water.
Carbohydrates are the main source of energy for a cell.
The building materials of cells are proteins and lipids.
The main material is nucleic.
Cells repair/grow damaged/healthy cells
Ex: Stomach digesting food.
Response to Surroundings
Living things use their stimulus to react.
The ways that stimuli can sense things through
Growth and Development
A change that make an organism a more complex organism.
Organisms need to create new cells to grow.
Organisms have to make offspring to not go extinct.
The Needs of Living Things
Autotrophs make their own food.
Food makes energy.
Without energy the organism can't do anything
Heterotrophs need to find their own food. (They can't make their own.)
All organisms need water.
Water makes up to 90% of human blood.
Water dissolves chemicals in organisms.
Every organism needs shelter to live in.
Since Earth is only so big sometimes organisms have to fight for shelter.
Even trees need to fight for water and minerals.
Stable Internal Connections
Every organism needs to have stable conditions inside of their bodies.
Homeostasis keeps the conditions inside of the organism just right for the cells to function.
When you are dehydrated chemicals in your body tell your brain to feel thirsty.
Life Comes From Life
Flies go into uncovered jar.
Then lay eggs that turn into more flies.
The flies can't enter the covered jar, so that proves that life can't come from inanimate objects.
He boiled broth to prove that there was no bacteria in the broth.
Then he got normal un-boiled broth
They both go the same result
This proved that spontaneous generation didn't exist.
