Cells
Cells are
the smallest known functioning units of life.
The six characteristics of living things are?
They are made of Cells
Need Energy
They Grow and develop
They respond to their environment
They reproduce
They have adaptations that allow them to live in their environment
Used to pump blood through the body
Heart
Heart, Arteries, Veins, Capillaries and blood are they
Circulatory system
a “controllable gateway” that lets needed materials in and water materials out
Cell Membrane
All Organisms are made up of
at least one cell
All living things are made of cells,
All organisms are made up of at least one cell and all cells come from other cells
Microscopic in size
A Large Organism such as a tree can have trillions of cells
Non-living things are are not made of cells
The organ that is responsible for the exchange of oxygen and Carbon dioxide in the body
lungs
Nose, Mouth, Trachea, Diaphragm, Bronchi and lungs are a part of the body's
Respiratory System
The “frame” of the cell. Found in plant cells but not in animal cells, it provides strength and support to plants
Cell Wall
Tissues are
groups of similar cells working together to perform a specific function
An organism gets their energy from
Organisms get energy from their environment
Animals use their environment, plants use the sun
Produces acid to help break down food into digestible pieces
Stomach
Salivary Glands, Mouth, Esophagus, Stomach, Liver, Pancreases Gallbladder, small intestine and Large Intestines' are a part of the body's Digestive System
Digestive System
a “command center” that direct all cellular activities such as movement, growth and other life functions
Nucleus
Organs are
a group of tissues that work together to perform a specific function
An organism responds to their environment through
stimulus. This is anything that causes a response in an organism.
Filters the body's blood and aids in digestion
liver
Brain, Spinal cord, Nerves and sensing organs are a part of the body's
Nervous system
The “powerhouse” of the cell where chemical reactions occur that convert the energy the cell receives into a form it can use
Mitochondria
Organ Systems are
a group or organs that work together to perform a certain task, such as digestion or breathing
True or False: Organisms only grow for so long, then they are done growing.
False: Growing involves getting bigger but after that they continue to produce new cells and are always growing new things.
Removes chemicals and other toxins from the body
Kidneys
Kidneys, Bladder, Lungs, Skin and Liver are a part of the body's
Excretory System
The “solar panels” of the cell. They are found in the cells of the green parts of plants. They carry out photosynthesis, converting the sun’s energy into food for the cell
Chloroplasts
