C3 L1 - Cell Division and Cell Cycle Flashcards
Cell Cycle
Growth
Develop
Replace
Interphase
A period of Growth and Decelopment
3 parts in Interphase
Rapid growth, replication, or copying
Copying DNA, genetic
Preparation for cell division
Organelles Replication
Makes a copy of each organelle
What can copy themselves on their own
Mitochondrion
Chloroplasts
Mitotic Phase
Mitosis
Cytokenesis
Daughter Cells
Mitosis
The nucleus divides
Cytokenisis
The cytoplasm and contents divide
Daughter Cells
The two new cells that result from Mitosis and Cytokinesis
Phases of Mitosis
PMAT
Prophase
Metaphase
Anaphase
Telophase
Prophase
Nucleus and nuclear membrane disappear
Metaphase
Spindle fibers push chromosomes to the middle
Anaphase
Opposite directions
Anaphase equals
Away
Telephone
Two identical neclei
Cytokinesis
Division of cytoplasm
Cytokinesis equals
Cytoplasm
Cyto=cyto
Plant cells
A new cell wall forms in the middle of cell; vesicles join to form a cell plate
Result of Cell Division
Reproduction
Growth
Replacement
Repair
Reproduction
In some unicellular organisms
Growth
Cells divide
Replacements
Replaces cells that wear out or damaged
Repair
Produces new cells that patch broken pieces together
Repair doesn’t repair
Nerve or muscle cells
When a cell divides each
Cell has some
Chromosome is what shape
X
Chromatin
Stringy
Chromosome
Tightly
Chromotad
Half of chromosome
Which cycle takes the longest
Interphase
Why does interphase take the longest
Always growing , functioning , organelle replicating
Sister chromatids
Identical strands of chromosome
Centromere
sister chromatid are connected
Two main phases
Mitotic and Interphase
After cell division
The parent cell divides again
The cell cycle is important for reproduction in ___ organisims
Unicellular organisms
The most important result of the cell cycle is two
Identical cells
The cell cycle is important for growth and repair in
Multicellular
