UNIT ONE
Who discovered cells?
Robert Hook
Which cells have a cell wall and which don't?
Plant cells have a cell wall while animal cells don't.
What is the first step in cell division?
G1; the growth phase
What is the difference between a genotype and a phenotype?
The genotype is the genetic format of a person. Phenotypes are the physical aspects that one can see in a person.
Where do plants store the energy that they get from the sun?
In their leaves.
What is the correct format for a hypothesis?
If the (independent variable) affects the results, then (increasing/decreasing) the (independent variable) will (increase/decrease/affect) on the (dependent variable).
What is the function of the mitochondria?
It is to help perform cellular respiration in eukaryotic cells.
What could happen if a cell does not divide properly?
If a cell does not properly divide, it can lead to serious diseases and effects (ie. cancer).
A heterozygous mother that has brown hair and a father that is homozygous recessive for blonde hair, what are the possible genotypes for their children?
Aa
Aa
aa
aa
How does a plant absorb energy?
Using photosynthesis and absorbing sunlight.
Who was credited for the invention of the improved modern microscope?
Anton van Leeuwenhoek
What is the function of the cell membrane?
It protects the cell while filtering out different nutrients and waste in and out of the cell.
What "check" on the process of cell division?
Cells go through a checkpoint that confirms whether or not the cell can continue into the next phase.
If the original DNA sequence is GCT ACC GTA ATC, what is the mRNA strand for it?
CGA UGG CAU UAG
What is the chemical equation for the process of Photosynthesis?
6CO2 + 6H2O + light energy = C6H12O6 + 6O2
