What is interphase?
Non-dividing part of the cell cycle
What is the cell cycle?
Repeating steps of events in the life of a cell
G1, S, and G2 are all apart of what process?
Interphase
What are the five steps of cell division?
Prophase, metaphase, anaphase, telophase, cytokinesis
What happens in G1?
Gap of time, cell grows and matures to size
What happens in S?
Synthesis of DNA; exact copy of all DNA in the nucleus
What happens in G2?
Gap of time, cell prepares for cell division
What happens in prophase, metaphase, anaphase, and telophase?
Division of the nucleus
What happens in cytokinesis?
Division of the cytoplasm
What is the cell cycle controlled by?
Proteins
How do multicellular organisms grow?
Making more cells
Where do new cells come from?
Pre-existing cells
What are new cells used for?
Growth or repair of damaged tissues
What is cell reproduction called?
Cell division
What is cell division?
Process by which cells produces offspring cells
What are offspring cells also called?
Daughter cells
How many cells are prduced every second in humans?
25 million
How long is the cell cycle?
The length is different from one cell to another
When does cancer occur?
When cells grow uncontrollably
What is a tumor?
Swelling of a part of the body caused by an abnormal growth of tissues
What is benign?
Not harmful in effect, in a particular tumor
What is metastasize?
Spread to other sites in the body by metastasis
What is cancer?
Disease caused by an uncontrolled division of cells in the body
