Organelles
The organelle that functions in energy production; the power factory of the cell
What is the Mitochondria?
The basic structural and functional unit of living organisms
Thought the objects looked liked individual rooms in a monastery, which were called cells
who is Robert Hooke?
Supports the plant (allows it to grow tall)
what is the cell wall?
A cell that lacks organelles.
What is a Prokaryotic cell?
A membrane-bound organelle in eukaryotic cells that contains the DNA; the control center of the cell
What is the nucleus?
A self-contained living thing
What is an organism?
A theory that states the following: all life is made up of cells, cells are the fundamental unit of life, and all cells come from preexisting cells
What is cell theory?
Controls movement of materials in and out of the cell
What is cell membrane?
A cell that has many types of organelles with many different functions.
What is a Eukaryotic cell?
The organelle that stores water and food in both plant and animal cells
What is the vacuole?
A collection of organs that work together to perform specialized functions
What is an organ system?

Who is Mathias Schleiden?
Large, oval shape in the center of animal cells and at the edge of plant cells
What is the Nucleus?
tightly packed DNA found only during cell division
What is a chromosome?
The jellylike material inside the outer membrane of a cell that holds the nucleus, organelles, and other components of the cell
What is the Cytoplasm?
A collection of similar tissues joined together into a structure that performs specialized functions
What is an organ?
Proposed that all cells result from the division of previously existing living cells
Who is Rudolph Virchow?
Uses energy from the sun to make food (sugar and oxygen) for the plant (photosynthesis).
What is Chloroplast?
a membrane that separates the nucleus from the cytoplasm in eukaryotic cells
What is a nuclear envelope?
A lipid barrier that encloses the cytoplasm and controls what enters and exits the cell
What is the cell wall?
A mass of similar cells that perform a specialized function
What is tissue?
Concluded that all animal tissues are composed of cells, too.
Who is Theodor Schwann?
Breaks down sugar molecules into energy (ATP - the chemical energy of the cell)
What is Mitochondria?
a structure in a chromosome that holds the two chromatids together
