Cancer Cells
A cell is rapidly growing out of control. What could be the cause?
What is cancer
What is the non dividing part of the cell cycle?
What is interphase.
During which phase do the sister chromatids separate into individual chromosomes and are moved apart?
What is anaphase
Discuss ways plant cells are different from animal cells.
What is plant cells have a cell wall, and are boxy in shape, not oval. They have chloroplasts which is where photosynthesis takes place.
What allows the cell to proceed only when certain processes have happened inside the cell?
What is internal regulators
True or False
Mutations in genes could cause uncontrolled cell growth in genes that control the cell cycle
What is true
What is the dividing part of the cell cycle called?
What is mitosis
What happens in prophase?
What is the basic unit of life?
What is the cell.
A natural process of programmed cell death.
What is apoptosis
True or False
All tumors are cancerous.
What is false
Describe the cell cycle.
Interphase- The nondividing part of the cell cycle.
It has 3 phases (G1, S & G2).
Mitosis- The dividing part of the cell cycle.
PMAT
Cytokinesis
What happens in metaphase?
What is the chromosomes line up in the middle.
What is the difference between a prokaryotic and an eukaryotic cell?
What is a prokaryotic cell does not have a nucleus and a eukaryotic cell has a nucleus.
What regulates the timing of the cell cycle in a eukaryotic cell?
What is cyclin
Cancer cells lack the ability to recognize and control cell growth and reproduction, as a result they
What is, they replicate again and again.
When the chromosomes are replicated during this phase.
What is the S phase
What structures help move the chromatids during mitosis?
What are the spindle fibers
Cells have ______________surface area to volume ratio for greater diffusion of substances in and out of the cell.
What directs cells to speed up or slow down the cell cycle?
What is external regulators.
What is a disorder in which some of the body’s own cells lose the ability to control growth?
What is cancer
During which phase does the cytoplasm pinch in half?
What is cytokinesis
Describe the final phase of mitosis.
What is, Telophase, Two identical daughter cells are produced.
Why are cells small?
What is To maximize the surface area to volume ratio
One effect of an internal regulator is that a cell will not begin mitosis until
What is all its chromosomes have been replicated
