The Cell Cycle & Cell Division_11.1 Flashcards
(39 cards)
The process which most cells in an organism go through a cycle of growth, development, and division.
Cell cycle
Through this cycle, organisms grow, develop, replace old or damaged cells, and produce new cells.
Cell cycle
The two main phases in the cell cycle are…
Interphase and the mitotic phase
The phase in the cell cycle when cells grow and develop
Interphase
A cell spends most of its life in…
Interphase
During the Interphase, most cells go through…
G1, S, and G2
What occurs during G1?
Rapid growth and replication, or copying, of the membrane-bound structures called organelles
What occurs during S?
Copying of DNA, and the genetic information in a cell
What occurs during G2?
Preparation for cell division
The phase in the cell cycle when cells reproduce
Mitotic phase
The shorter phase of the cell cycle
Mitotic phase
The mitotic phase has two stages:
Mitosis and cytokinesis
Division of nucleus and its contents
Mitosis
Division of cytoplasm and its contents
Cytokinesis
The mitotic phase creates…
Two new identical cells
At the end of the mitotic phase the original cell…
No longer exists
The time it takes to complete the cell cycle depends on…
The type of cell that is dividing
Eukaryotic cells contain membrane-bound…
Organelles
The time it takes for a cell to complete the cell cycle _______
Varies
A cell with membrane-bound structures
Eukaryotic
Newly produced cells begin interphase with…
A period of rapid growth
Rapid growth can also be described as…
Cells getting bigger
After rapid growth comes…
Cellular activities such as making proteins
Next, actively dividing cells…
Make copies of their DNA and prepare for cell division
