Flashcards in Finals Biology Deck (40):
Where does the energy that a plant needs come from?
What is produced during photosynthesis?
When BTB turned yellow what did it mean?
Co2 was detected
What does it mean when BTB stayed blue?
No Co2 was detected
What matter do plants take in to make their food?
Co2 and H2o
Do plants do both photosynthesis and cellular respiration? Why?
Both; the take in/give off energy
Do prokaryotic cells have a nucleus?
What is the amount of prokaryotic cells?
Do prokaryotic cells have complex organelles or ribosomes?
Do eukaryotic cells have a nucleus?
What is the amount of cells in a eukaryotic cell?
Do eukaryotic cells have complex organelles or ribosomes?
Which cell organelle stores genetic information?
Which cell organelle produces ATP from glucose?
What are 3 organelles found in a plant cell that is not found in an animal cell?
Cell wall, central vacuole, chloroplasts
What does an enzyme do to the amount of energy needed to start a reaction?
I'm an enzyme reaction, what has to be a perfect match with the enzyme in order for the reaction to work?
What can increase the rate of an enzyme reaction?
What 3 substances get cycled around in an ecosphere between algae, shrimp, and bacteria?
Carbon oxygen nitrogen
What substance is used by the shrimp and by the bacteria?
What is a closed system?
Matter does not enter or leave
What is the original source of energy for nearly all of life on earth?
Which type of organisms provide all of the energy to support an ecosystem?
What molecule in plants stores energy from the sun and is the main product of photosynthesis?
What percentage of the energy gets passed from one trophic level to the next in a food chain?
Where does the energy that is not passed on from one level in a food web, go?
Used by organism to live
3 molecules that makeup DNA nucleotide
Deoxyribose sugar, nitrogen base, phosphate
3 molecules that make up RNA nucleotide
Ribose sugar, nitrogen base, phosphate
What are the strong/weak bonds in the DNA nitrogen base?
AT & CG
What is the information stored in DNA used for?
Make copies (mRNA)
How many nucleotides make up the codon for one amino acid?
A segment of DNA that codes for a specific trait/protein
What determines an individual's traits?
The genes you inherit from your parents
Where in a cell are proteins assembled?
How does the information in DNA get from the nucleus to the ribosome?
Bonds between bases break, RNA copies DNA code, RNA goes to ribosome
What cell process creates daughter cells that are genetically different from the original parent cells?
What is the goal of creating genetically different sex cells? (Gametes)
Diversity and a greater survival chance
Contains 2 complete sets of chromosomes (1 from each parent)
Single set of unpaired chromosomes (half of diploid cell)
