Cell Theory
This scientist proposed that all living things are made of cells.
Who is Schleiden?
Cells that do NOT have a nucleus.
What are prokaryotic cells?
The “control center” of the cell.
What is the nucleus?
The cell membrane is selectively ___________.
What is permeable?
Movement of particles from high to low concentration.
What is diffusion?
This states that cells are the basic unit of structure and function in living things.
What is cell theory?
Cells that DO have a nucleus and membrane-bound organelles.
What are eukaryotic cells?
This organelle produces energy for the cell.
What is the mitochondria?
The membrane is made of a phospholipid ___________.
What is bilayer?
Diffusion of water across a membrane.
What is osmosis?
This part of cell theory says all cells come from pre-existing cells.
What is Virchow's contribution?
This type of cell contains a cell wall, chloroplasts, and a large central vacuole.
What is a plant cell?
This organelle modifies and packages proteins.
What is the Golgi Apparatus?
These molecules help substances move across the membrane.
What are transport proteins?
Transport that requires energy.
What is active transport?
The cell theory was developed using observations of plant and animal tissues.
What are cells?
This structure is found in plant cells but NOT animal cells.
What is a cell wall?
Ribosomes are responsible for this process.
What is protein synthesis?
The cell membrane maintains this inside the cell.
What is homeostasis?
Transport that does NOT require energy.
What is passive transport?
These two scientists helped develop the original cell theory.
Who are Schleiden and Schwann
Bacteria are examples of this type of cell.
What are prokaryotic cells?
This organelle contains digestive enzymes that break down waste.
What is a Lysosome?
This model describes the structure of the cell membrane.
What is the fluid mosaic model?
This type of transport moves large particles using vesicles.
What is endocytosis or exocytosis?
