Characteristics of Life
Any living thing
Organism
Made of many cells
Multi cellular
The system that supports the body
Skeletal system
Single celled organism without a nucleus
Bacteria
Organelle that allows materials to enter OR leave the cell
Cellular Membrane
The passing of genetic material from one generation to the next
Reproduction
Tiny organ-like structures within a cell
Organelle
The system responsible for body’s movement
Muscular system
Eukaryote; they are heterotrophs that feed by absorbing food through cell walls
Fungi
Passive diffusion of water across a cell's membrane
Osmosis
Change in a population over time
Evolution
Powerhouse of the cell; where cellular respiration takes place
Mitochondria
The system that brings in oxygen and removes carbon dioxide
Respiratory system
Tiny, nonliving particle that enters then reproduces inside a living cell
Virus
Molecules moving from high concentration to low concentration, no energy is used
Diffusion
The basic unit of life
A cell
Where DNA is stored
Nucleus
the system for controlling the body’s responses to change in and outside the body.
Nervous system
A substance that contains weakened or killed diseases but allows body to produce chemicals that eventually destroy the disease
Vaccine
The process that allows material to exit the cell
Exocytosis
Having an internal environment that is stable even when there are changes in the external environment
Homeostasis
Explains the relationship between cells and living things. 1. All living things are made of cells. 2. Cells are the basic units of structure and function in living things. 3. All new cells come from existing cells.
Cell Theory
A body structure made of different kinds of tissue that work together
Organ
The system that protects the body from infectious agents
Immune system
The process by which materials enter the cell
Endocytosis
