The Cell Cycle
growth and repair
What is the purpose of the cell cycle?
Controls the passage of materials in and out of cell
What is the cell membrane?
The need of an organism to stay stable.
What is homeostasis?
the basic unit of life
What is the cell?
Digests foreign substances and worn out cells
What are Lysosomes?
The process of cell division.
What is Mitosis?
Main purpose of organelles
What is making proteins?
The output/product of the system is increased.
What is a positive feedback loop?
Specialized structures in a cell that perform a specialized task.
What are organelles?
This has no nucleus and is unicellular
What is prokaryotic?
The cell grows, duplicates organelles and doubles its DNA.
What is interphase?
This jelly-like structure holds everthing in place in the cell.
What is cytoplasm?
The spreading out of molecules across a membrane until equilibrium is reached
What is Simple Diffusion?
All cells come from other cells
What is the Cell Theory?
Type of cell that has membrane bound organells
What is the Eukaryotic Cell?
These cells can turn into a number of different kinds of cells.
What are stem cells?
Its job is to protect the DNA (genetic material of the cell)
What is the nucleus?
Diffusion of molecules is aided by proteins that act as a channel or carrier.
What is Facilitated Diffusion?
This type of cell has a nucleus and divides by mitosis
What are Eukaryotic cells?
This organelle makes the proteins and is located on Rough ER.
What are Ribosomes?
Cells the undergo a process of programmed death.
What is apoptosis?
Makes and packages proteins.
What is Rough Endoplasmic Reticulum (ER)?
When a cell uses energy to pump molecules across membrane.
What is active transport?
All cells have these 4 things.
What is Genetic material, cytoplasm, cell membrane & Ribosomes?
The "mini carts" of protein transportation
What are 'vesicles'?
