Programmed cell death
What is apoptosis?
100
This group of proteins tells your cells, "Go ahead; you can divide."
What are growth factors?
100
This is technically not a phase of mitosis, but rather a preparation period for the cell before mitosis that involves replicating DNA and organelles and increasing in size.
What is interphase?
100
This group of diseases affects many organs of the human body, and occurs when cells stop listening to growth factors and thus grow without stopping.
What is cancer?
100
A group of cells that work together to perform a similar function.
What is (a) tissue?
200
In sexual reproduction, all life has its roots in this process, which occurs in both the organism's parents and leads to haploid cells.
What is meiosis?
200
Cells in a developing blastula answer the question, "What will you be when you grow up?" in this process.
What is determination?
200
The final phase of mitosis, the cell begins to split into two daughter cells in this process, the chromosomes begin to uncoil and return to their normal "spaghetti" stage, and nuclear membranes are built around the chromosomes.
What is telophase?
200
This tumor is "kind" because it has not spread cancer cells to the rest of the body.
What is benign (tumor)? (Acceptable: a benign tumor)
200
A group of tissues working together to perform a similar function.
What is (an) organ?
300
It "mit" seem easy, but this process actually requires many steps -starting with the replication of DNA and ending after the formation of two new nuclear membranes.
What is mitosis?
300
Prokaryotes don't grow up; they just make new children with this simple asexual division process.
What is binary fission?
300
In this phase, the cell gets ready for the "big divide" by lining up the chromosomes in the center of the cell.
What is metaphase?
300
A ____ tumor is definitely "evil," because chances are high that this tumor has spread the cancer throughout the body.
What is malignant?
300
A group of organs working together: two examples of this are integumentary and muscular.
What is (an) organ system?
400
This process results in two identical sister cells.
What is cytokinesis? (mitosis accepted)
400
These cells can grow up into any cell they want, and are only present in developing embryos before they undergo determination and differentiation.
What are (totipotent) stem cells?
400
In this phase, the cell's spindle fibers get active, and the nuclear membrane breaks down.
What is prophase?
400
When cancer cells break away from a tumor, they are ____.
What is metastasizing?
400
As cliquish as cells can be, they all work together to maintain this condition, which is critical for survival.
What is homeostasis?
500
The formation of gametes: spermato____ and oo____.
What is genesis?
500
All eukaryotes and multi-cellular prokaryotes start as a single cell, yet from that cell comes many different kinds of cells, thanks to this process when cells begin to express only certain genes that relate to their job.
What is (cell) differentiation?
500
The cell has a total of 92 chromatids in this phase.
What is anaphase?
500
Some examples of this are DDT, smoking and even viruses.
What is (a) carcinogen?
500
The highest level of cell organization, examples of this range from a club moss to a slime mold to algae to a human.
What is (an) organism?
