Cell Structure
The ratio that determines how large a cell can grow
The surface area to volume ratio
The term uniquely describing prokaryotic cell division
Binary fission
The phase of the cell cycle where the golgi apparatus is duplicated
G2
An issue during this phase of the cell cycle is often responsible for cancer
S phase
The number of cells produced after 3 rounds of mitosis
8 cells
The structure of chromosomes (four components in order)
DNA -> Histones -> Chromatids -> Chromosomes
The amount of chromosomes in a sperm and/or egg cell
23 (1/2 normal)
The structure connecting the centrioles to the centromeres
Spindle fibers
Proteins that tell the cell to stop or start dividing
Regulatory proteins
The term for programmed cell death
Apoptosis
Draw two ways cells can increase their surface area to volume ratio
-Smaller size
-Ridges/texture
The structure that forms in between a dividing plant cell
Cell plate
The protein that spikes in concentration at the end of each phase in the cell cycle
Cyclins
3 risk factors for cancer
Tobacco
Disease
etc.
The metal band Mr. Jacques played recently
Iron Maiden
Draw a chromosome labeling the sister chromatids and centromere
-Two sister chromatids
-Centromere in the middle
The advantages of asexual reproduction
-More efficient (less energy/time)
-Can create large population quickly
S phase
External regulatory protein
The term for unicellular eukaryotes
Protista (protists)
You are observing a dividing cell with a cell wall, but no cell plate. What type of cell might you be observing?
Bacteria
The four reasons for cell division
-Reproduction (asexual, prokaryotic cells)
-Growth/Development (organism needs to get bigger)
-Repair (healing)
-Replacement (cells die or are shed)
A malformed centriole would interfere with which phase of mitosis
Prophase
An explanation for why there is no cure for cancer
-Cancer varies by cells, people, etc.
-Cancer camouflages in our own body
The reason sperm and egg cells have 1/2 the DNA of a normal cell
Genetic variation in offspring
