What organelle in a cell stores water, nutrients, and pigments
|
Produces lipids, phospholipids, and steroids.
Breaks down toxins.
Explain the function of the smooth ER
|
1952
When was DNA discovered to be genetic material?
|
it breaks down and recycles cell parts
What is the purpose of a lysosome?
|
temperature, whether phospholipids are saturated or not, and how many big molecules are embedded
What determines if cell membranes are more liquid or more solid?
|
Sunlight, water, and carbon dioxide
What are the reactants of photosynthesis?
|
rRNA and protein
What is a ribosome made up of?
|
Chloroplasts
Which organelle is responsible for photosynthesis?
|
plant cells have a cell wall
plant cells have chloroplasts animal cells have centrioles
3 differences between plant and animal cells are....
|
The inside
If E. coli are infected with T2 viruses that have radioactive DNA, would you expect the INSIDE or the OUTSIDE of the cell to be radioactive?
|
Oxygen and sugar
What are the products of photosynthesis?
|
the Nucleus
Where is DNA stored in a cell?
|
1953
When did people start thinking that DNA was a double helix and not a triple helix?
|
proteins are large molecules that are very specific in function
Why did researchers in the 1940's think that protein was the genetic material?
|
DNA can easily reproduce -- it uses the extra strand to make double-stranded copies of itself.
What is the importance of the fact DNA is double stranded (rather than single stranded)?
|
Greater number of chloroplasts
What separates mesophyll cells from other types of cells in a plant?
|
Proteins
In the 1940's, what was thought to be the genetic material?
|
They have internal membranes
How do eukaryotic cells compensate for their surface area to volume ratio?
|
1,000 times
How much bigger are eukaryotic cells than prokaryotic cells?
|
The males have different traits than the females.
How can you tell if a species has undergone sexual selection or not?
|
mRNA
What is used to carry orders from the DNA to the rest of the cell?
|
Countertransport
What form of transport requires energy and solutes move in the opposite direction to each other?
|
Large, polar molecules
What kind of molecules need energy to cross a membrane?
|
Clump of ribosomes and DNA
What is the nucleolus made up of?
|
shrinking population
nonrandom mating mutation movement (immigration and emigration)
What 5 categories of cards did you draw in the Evolution Game that changed the gene pool of your organisms?
