Ch. 3 Cell Structure and FunctionCell Membrane = homeostasis Active vs Passive Osmosis vs diffusion
Methods of Transport Across a Cell Membrane
???

Methods of Transport Across a Cell Membrane
???– Does not require energy– Particles move from _____ concentration to
_______concentration.
???????
Methods of Transport Across a Cell Membrane
Passive Transport Movement of water through a semi-
permeable membrane from an area of high water concentration to an area of low water concentration.
?????
Methods of Transport Across a Cell Membrane
Passive Transport
–??? Movement of particles through a cell membrane by
means of a transport protein. Down the concentration gradient Does NOT require energy.
Methods of Transport Across a Cell Membrane
???– “Cell eating”– A cell takes in macromolecules or other
substances when regions of the plasma membrane surround the substance, pinch off, and form a vesicle within the cell.
Methods of Transport Across a Cell Membrane
??????????????????– A cell secretes macromolecules –waste,
hormones, neurotransmitters, etc.

SYNTHASE
For each glucose molecule that enters cellular respiration, this produces up to 32 ATP molecules
Respiration and Photosynthesis
???– Process of using energy from the sun to
produce sugars (glucose)
– 6CO2 + 6H2O + Light Energy C6H12O6 +6O2
– Occurs in ____?_______of plants and some algae
– Part 1 and Part 2 ?
Photosynthesis
???
???
How are photosynthesis and respiration related?
Respiration and Photosynthesis
Where and how are excess sugars stored in plants?
Excess sugars are stored as ?????? in the roots.
This is a polymer of glucose.
Where and how are excess sugars stored in animals?
Excess sugars are stored as glycogen in the liver of animals.
Glycogen is a polymer of glucose.
Ch. 5 Cell Growth and Division
Define the phases of the cell cycle.What factors regulate the cell cycle?Binary Fission compared to Mitosis Mitosis compared to Meiosis e.g. haploid and diploid

Why is meiosis required for sexual reproduction?

Comparing Mitosis and Meiosis:
Genetics/ DNA
Heredity and Mendelian Genetics– Genetics: The study of heredity (the passing of
traits from parents to offspring)
– ???????: The father of genetics.
– DNA: Consists of many ???
– ???: Alternate version of a gene
????????– Make up most of the
body’s tissues and organs
– 2 of each chromosome for a total of 46
????????– Sperm cell (male) or
egg cell (female)– Only 1 kind of each
chromosome; – Half #
chromosomes in body cells (23)
Genetics/ DNA
Dominant and Recessive Traits ?????? Allele
– Gene that is fully expressed.– Masks/ “speaks louder than” a recessive allele.
?????? Allele– Masked/not expressed if dominant allele is
present.– Only expressed if dominant allele is absent.
Genotype
The genetic makeup of an organism– ??? : having two of the same allele BB bb– ??? : having two different alleles. Bb
_____ ______: having two dominant alleles BB_____ ______: : having two recessive alleles bb______ : having one of each allele Bb
?????
The physical and physiological traits of an organism
How the genes are expressed What you would see in a photograph
Example:
In peas, Y is a dominant allele that instructs for yellow seeds; y is a recessive allele that produces green seeds.
DNA/ Genetics A __________ can be used to predict the
genotypes and phenotypes of the offspring produced by a given genetic cross.
Generations– ??? (P): The organisms involved in the initial cross– ????? (F1): The offspring of the Parental Generation– ???(F2): The offspring of First Filial Generation
Example: A chicken and a rooster mate. The chicken has
white feathers and the rooster has brown feathers. Brown is dominant, and white is recessive. Assuming the rooster is heterozygous, predict the frequency of each genotype and phenotype in their offspring.
What is the cellular process that determines which alleles an offspring will receive from their parents? Meiosis
Practice: 1. A plant that is homozygous dominant for height
is crossed with a plant that is homozygous recessive. (T = tall; t = short).
Use a Punnett Square to predict the genotypic and phenotypic ratios of the F1 generation.
Practice:
2. Using question number 1, what would be the genotypic and phenotypic ratios of a cross of two F1 individuals?
DNA/ Genetics
Determining Sex
Human male: ?? Human female: ??
Which parent determines the
sex of a human offspring? ????
What is the probability of having a boy? A girl? ???
DNA/ Genetics
Sex linked traits
Typically carried on the X chromosome
Example: hemophilia, color blindness.
Disorders occur more often in males than females. Why?
Males have one X chromosome, so if one is defective, they do not have a backup copy as do females.
DNA/ GeneticsMutation Definition?
A change in DNA can lead to a change in the __?____ coded for by that gene.
A change in the protein structure can lead to certain disorders, for example, sickle cell anemia.
Genetic Exceptions to the rules!
???Both alleles contribute to
the phenotype
Example: A red cow crossed with a white cow results red cows with white blotches.
Genetic Exceptions to the rules!???
A gene has more than one alleleThe result is various expressions of the gene.Example: various hair colors in mice.
Genetic Exceptions to the rules!???
Traits controlled by more than one geneEx. Human skin color
More than 4 different genes control this trait, which is why we all look so different!
