Cell Theory
The small unit of life that performs life functions.
What is a cell?
The simplest level of organization.
What is a cell?
The organelle of a eukarytoic cell that controls all of it's functions.
What is a nucleus?
The specialized parts of a cell.
What is an organelle?
The water pressure pressing against a cell wall, allowing a plant to stand up tall.
What is Turgor Pressure?
The first tenant of Cell Theory.
What is "All living things are composed of cells"?
A whole, complete living thing.
What is an organism?
The organelle that controls what comes in and out of the cell.
What is the cell membrane?
The jellylike material that supports the other organelles.
This process is an essential proof to cell theory, but we are just splitting cells.
What is reproduction?
Produced the first compound microscope.
Who is Zacharias Janssen?
A group of tissues that come together in an organism to perform a specific job.
What is an organ?
The organelle in plant cells that converts light energy into chemical energy.
What is the chloroplast.
The organelle that converts energy in the cell.
What is the mitochondrion?
A plants response to stimuli.
What are tropisms?
This tenant of cell theory has been portrayed through examples of asexual reproduction such as binary fission.
What is "All cells come from preexisting cells."
A level of organization in organisms, such as when roots, stem and leaves work together.
What is an organ system?
The large organelle that stores water and works with the cell wall.
What is a vacuole?
An organelle in animal cells that can be present in multiple small groups or not present.
What is a vacuole?
What is movement, respiration, sensitivity, growth, reproduction, excretion, and nutrition?
Examples of this level of organization of organism include nerve, connective, epithelial, and muscle.
What is tissue?
The organelle in plant cells that is responsible for providing the organisms rigid shape.
What is a cell wall?
The two organelles not present in animal cells.
What are chloroplasts and cell wall?
