It states that all organisms are made up of cells, cells are the smallest unit of life and cells come from preexisting cells through cell division
Cell Theory
Gets rid of liquid waste from the body
Excretory System
They respond to pain, pressure and temperature
Mechanoreceptors
An individual, free-living, independent thing such as, a plant, animal, fungus, bacterium, archaean or protist
Organism
It's the control center of the cell and contains the cell's DNA
Nucleus
He was the scientist that coined the term "cell" after viewing a thin slice of cork

Reproduction
Uses hormones to communicate with the body
Endocrine System
They are stimulated by chemicals and responsible for smell and taste
Chemoreceptors
A chemical that is released when an electric impulse reaches the end of a neuron's axon and transmits a signal to the dendrite of the next neuron.
Neurotransmitter
The gel-like fluid where the organelles are found
Cytoplasm
Organisms made up of one or more cells that have a nucleus and membrane bound organelles
Eukaryotes
Exhales waste gasses such as carbon dioxide
Respiratory System
They are stimulated by light and responsible for vision
Photoreceptors
Tiny air sacs in the lungs, surrounded by capillaries, where oxygen and carbon dioxide are exchanged
Alveoli
The organelle responsible for cellular respiration
Mitochondria
The two substances that react to produce energy during aerobic cellular respiration.
Oxygen and Glucose
Enables the body to move
Muscular System
They are located in the center of the retina
Cones
A single-celled organism that has no nucleus or membrane bound organelles
Prokaryote
Free-floating or attached to the E.R., these organelles are responsible for assembling amino acids to create proteins
Ribosomes
