Photosynthesis
Almost all plants are autotrophs, meaning they generate what from what.
sugar from carbon dioxide and water
Energy that can be used by cells
ATP
What organelle is responsible for maintaining homeostasis?
cell membrane
Differences between genotype and phenotype
Genotype is the pair of alleles
phenotype is physical traits
What is transcription?
mRNA being made as a complementary form of DNA
Organelles in the plant cell where photosynthesis occurs
chloroplast
What organelle is responsible for cellular respiration?
Mitochondria
In eukaryotes where does transcription take place?
Nucleus
What is the differences between dominant and recessive?
Dominant - the form of a trait that always appears when an individual has an allele for it. Recessive - the form of a trait that only appears when an individual has two alleles for it.
What are the three types of RNA and what are their jobs?
messenger RNA- carries instructions for protein synthesis from nucleus to ribosomes
transfer RNA- carries amino acids to the ribosomes and matches them to the coded mRNA message
Ribosomal RNA- forms an important part of both subunits of the ribosomes.
Thick fluid in between the 2 membranes of chloroplasts.
Stroma
What type of cells do cellular respiration?
All cells
What organelle is responsible for protein synthesis during translation?
ribosomes
What is a codon
a group of three nucleotide bases in messenger RNA that specifies a particular amino acid
What are the 3 results of Franklin's research?
DNA is a helix
DNA is double stranded
The nitrogenous bases are on the inside of the two strands
Interconnected sacs in the Stroma.
Thylakoids
Why does photosynthesis only happen part of the day but cellular respiration happens 24 hours a day?
Photosynthesis requires sun light, cellular respiration does not.
What are the differences in structure and function of the smooth ER and rough ER?
Smooth ER: no ribosomes and makes lipids (fats)
Rough ER: ribosomes and makes proteins
What are the differences between codominance and incomplete dominance?
Codominance: The phenotypes for both alleles are clearly expressed.
Incomplete dominance:One allele is not completely dominant over another.
What are the 3 differences between RNA and DNA that we talked about in class?
RNA has Uracil DNA has Thymine
RNA is usually single stranded, DNA is usually double
The sugar in RNA is ribose instead of deoxyribose.
Stacks of thylakoids
Grana
What are the three stages of cellular respiration
Glycolysis, Krebs cycle, Electron Transport Chain
What is the job of the lysosomes?
Remove waste and old organelles from the cell
Make a dihybrid cross between AaBb x aaBb and state the probability of each genotype.
AaBB=1/8
AaBb=2/8
AaBB=1/8
aaBB=1/8
aaBb=2/8
aabb=1/8
What amino acid sequence is formed from this DNA sequence?
TACAAGTTTACTTCTCTA
Met-Phe-Lys-STOP
