Cells
The basic unit of life.
Cell
A lipid barrier that encloses the cytoplasm and controls what enters and exits the cell
Cell Membrane
A collection of similar tissues joined together into a structure that performs specialized functions
Organ
A membrane-bound organelle in eukaryotic cells that contains the DNA; the control center of the cell
Nucleus
Name the three inputs
Mechanical Input
Chemical Input
Electromagnetic Input
*DAILY DOUBLE*
A category of organisms made up of more than one cell and of different types of cells
Multicellular
A tough, protective barrier that surrounds the outer membrane of some types of cells
Cell Wall
A self-contained living thing.
Organism
A structure inside a cell that performs a specialized function
Organelle
Which input allows us to sense balance and gravity ?
Mechanical Input
A category of organisms made up of one cell
Unicellular
What something does.
Function
*DAILY DOUBLE*
A group of interacting, interrelated, or interdependent elements forming a complex whole
System
A dense, gel-like liquid that contains all the structures needed for the basic life functions of the cell
Cytoplasm
Which input allows us to sense hunger?
Chemical Input
Cells that do not have membrane-enclosed organelles such as mitochondria or a nucleus.
Prokaryotic cells
The organelle that functions in energy production; the power factory of the cell
Mitochondrion
A mass of similar cells that perform a specialized function
Tissue
Genetic material which contains instructions for making new organisms and for carrying out all functions that keep a cell alive.
DNA
Which input allows us to sense time?
Electromagnetic Input
A complex cell that has organelles surrounded by membranes. These include mitochondria and a nucleus.
Eukaryotic cells
DAILY DOUBLE!!!
A membrane-bound organelle in plants that is the site of photosynthesis
Chloroplast
Having characteristics that allow specific functions to be performed.
Specialized
A self-contained system within a larger system
Subsystem
What part of your body do you think is mainly responsible for allowing you to hear when a sound is being made? Explain.
The brain allows us to hear sounds. Ears also help, but without the brain, there would be nothing to process the information.
