More Cellular Transport
Passive transport that moves water
Osmosis
What art the two purposes of the cell cycle?
Growth and repair
While in the womb, the webbed fingers of the embryo undergo programmed cell death, also known as what?
Apoptosis
Research has shown that uncontrolled cell growth and development can lead to what disease?
Cancer
Growth and repair
Name the type of transport that requires energy, and moves molecules from an area of low concentration to an area of high concentration.
Active transport
Which type of tumor can cause tumors in other parts of the body?
Malignant tumors
How are stem cells different from other cells in the body?
They are undifferentiated cells that can turn into a number of different kinds of cells as needed.
What is the difference between a cancer cell and a normal cell?
Cancer cells divide uncontrollably
What happens during cytokinesis?
The cell membrane pinches in the middle until two equal cells are formed. (cytoplasm division)
Passive transport that moves oxygen and carbon dioxide in and out of the cell.
Diffusion
Internal regulation
Which organelle do animal cells use for cell division?
Substances that are known to produce or promote cancer.
Carcinogens
What are the four phases of mitosis and what happens at each?
Prophase: nuclear membrane dissolves and chromosomes become visible as sister chromatids.
Metaphase: Chromatids line up in the middle of the cell.
Anaphase: Sister chromatids pull apart
Telophase: nuclear membranes reform around chromatids.
Passive transport that moves glucose into the cell.
Facilitated diffusion
Level of organization represented by a group of different tissues working together to perform a complex function.
Organ
What happens during interphase?
The cell grows, and copies DNA.
True or false: Chromosomes line up in the middle of the cell during prophase.
False
What are the three phases of interphase and what happens at each?
G1: cell growth and making proteins
S: Chromosomes are duplicated
G2: cell growth and making proteins
Active transport that is used by white blood cells to capture bacteria.
Endocytosis
Put the following parts in the correct order from largest to smallest.
human being, neurons (brain cells), brain, central nervous system, nerve tissue
Human being
Central nervous system
brain
nervous tissue
neurons (brain cell)
If a cell has 46 chromosomes, how many will each of its daughter cells have AFTER mitosis?
46
Why is it important for cells of multicellular organisms to undergo mitosis?
Mitosis produces cells that are identical to the original dividing cell.
If a cell does not go through S phase of the cell cycle before mitosis, what might be wrong with the daughter cells?
There won't be enough chromosomes in the daughter cells.
