Reproduction and Development
Embryo
What is it called when cells lose control over their growth and division?
Cancer
What phase can you see visible chromosomes? Hint: This phase also condenses chromatin and breaks down the nuclear envelope
Prophase
What are thread like structures made of DNA and protein called?
Chromosomes
What is Cell Division?
Process by which a cell splits into two daughter cells. Key for growth, repair and reproduction.
What is the process when cells become specialized to preform specific functions?
A mass of uncontrolled dividing cells that can be benign or malignant?
What phase is when the sister chromatids separate and move to opposite poles of the spindle?
Anaphase
What structure in animal cells organize the spindle fibers during cell division?
Centrioles
What is Mitosis?
process of nuclear division in eukaryotic cells.
The ability of a cell to develop into any type of cell in the body is called?
Totipotent
What is it called when proteins start cell division based on needs of an organism?
Growth factors
What phase is when chromosomes align at the center of the cell?
Metaphase
What is the thread like form of DNA and protein found in the nucleus during interphase?
Chromatin
What is the longest phase of the cell cycle? What happens during this phase?
Interphase: Cell grows and replicates DNA
What is a hollow ball of cells that forms to develop into the embryo called?
Blastocyst
What is Apoptosis?
Programmed cell death to help remove damaged or unnecessary cells
What are the four phases of Mitosis in order?
1. Prophase
2. Metaphase
3. Anaphase
4. Telophase
What region of a chromosome where chromatids are joined and spindle fibers attach?
Centromere
What is Cytokinesis?
Process of dividing the cytoplasm of a parent cell into two daughter cells. Completing cell division.
A cell that is able to develop into many different types of cells/tissues in the body is called?
Pluripotent
What is the type of protein that regulates the cell cycle by controlling the timing of cell division called?
Cyclin
What is the difference between Cytokinesis in animal cells vs plant cells?
Animal Cell: Cytoplasm is pinched into two cells
Plant Cell: Cell plate or cell wall forms between two daughter cell
What is the difference between Prokaryotic and Eukaryotic chromosomes?
Prokaryotic chromosomes: a single DNA molecule
Eukaryotic chromosomes: DNA molecules wrapped around proteins called histones found in the nucleus
What are the three events in the life of a cell cycle?
1. Growth
2. DNA Replication
3. Cell Division
