It's Just a Theory
The cell theory states that all living things are made of these.
Cells
This organelle is often referred to as the cell's control center.
Nucleus
This process involves the movement of water across a cell membrane.
Osmosis
Moves through the cell membrane by osmosis

Water
The human body cells usually contain 23 pairs of DNA strands; these strands may also be called __________
Chromosomes
This scientist is credited with coining the term "cell" after observing cork under a microscope.
Robert Hooke
This organelle is filled with enzymes that break down waste in the cell.
Lysosome
This term describes how cells maintain a stable internal environment.
Homeostasis
This is not required in passive transport
gereyn
Energy
Bacteria reproduce through this process
Binary Fission
According to cell theory, cells are the basic unit of this.
Life
This organelle is known as the powerhouse of the cell.
Mitochondrion
The process by which cells convert glucose into energy is called
Cellular Respiration
We speed up reactions
enzymes
This is the phase of mitosis where chromosomes line up in the middle of the cell.
Metaphase
This scientist proposed that all cells come from pre-existing cells.
Rudolf Virchow
This organelle is responsible for photosynthesis in plant cells.
Chloroplast
The process in which DNA molecules make exact duplicates
Replication
The division of a cell into two identical daughter cells by the duplication of chromosomes.
Mitosis
Meiosis results in the formation of these types of cells.
Gametes
The discovery of these led to the development of cell theory.
Microscopes
This structure controls what enters and exits the cell.
Cell Membrane
When a cell splits into two identical cells
Binary fission
A solution with fewer dissolved particles
oohcpntyi
Hypotonic
This process occurs at the end of mitosis, resulting in two daughter cells.
Cytokinesis
