Cell Structure & Infectious cells
- Provides energy for the cell by breaking down sugar molecules in cellular respiration
Cytoplasm chloroplastMitochondriaGolgi apparatus
- Provides food for a plant cell by collecting energy from the sun during photosynthesis
Mitochondria chloroplastcytoplasmvacuole
- Allows material to enter or exit the cell & protects the contents of the cell
Cytoplasmcell wallcell membranevacuole
- What type of cell attaches to a cell membrane, injects genetic material, duplicates until the cell burst & dies
Parasitevectorvirusbacteria
- How does mold most often infect your body?
Gets on skin & cause irritation spores enter through a vectorbreath in spores to infect the lungs
- How does a cold virus most often get in your body?
Enters body through an open wound breath in through the mouth or noseeating contaminated food
- How would a parasite in the intestines most likely affect the digestive system?
Give you a stomach virus keep you from absorbing nutrientscause you to have hunger pains
- What process helps organisms use oxygen to get energy from food?
Cellular respirationphotosynthesisbreathingfermentation
- An organism that carries a disease that can be passed to humans.
Parasitevectorvirusbacteria
- Control center of the cell
Cytoplasmcell wallnucleusvacuole
- Tiny particle with nucleic acid surrounded by a protein coat that can only reproduce inside a living cell by injecting its DNA & causes an infection

Heredity
17.Use a punnett square to cross one heterozygous parent with one homozygous recessive parent parents: (use the letter E)
18.What percent is pure recessive? ______
19.What is the genotype and phenotype for the offspring in percentages for two heterozygous parents(R = round & r = wrinkled)
______
20.Number the following in order form smallest to largest:: Chromosome, allele, nucleus, DNA
- Use the pedigree to answer the following questions
- How many females express the trait of color-blindness? ______
- If the female from generation IV-6 marries a dominant male
(non-color blind), what is the chance of having a daughter
with the disorder? ______A son with the disorder? ______
Xn= color blind
XN = not color blind
22. What is it called when the actual DNA is altered in some way by inserting a needed gene directly into a cell to help cure a disease or improve a crop selective breeding pure breeding genetic engineering genetic resistance
23.What is it called when specific traits are selected in the parents in order to ensure they are passed to the offspring & the genes are not actually altered?selective breeding vaccinating genetic engineering genetic resistance
24.Incomplete dominance: If a Red flower (RR) is crossed with a white flower (WW) What percent of the offspring are pink (RW)
- Based on the pedigree below, what can we determine about the phenotype of the offspring in the 3rd generation?
______
