4. Two examples shown are plant cells and animal cells, but fungi and protists are also eukaryotic
5. Notice, plants have chloroplasts (for photosynthesis) and cell walls made of cellulose. Animal cells don't have these parts. Also, plant cells have a larger vacuole for storage.
69. What amino acid is coded for by the DNA ATA GAG READING THE CODON CHART First convert DNA to mRNA ATA GAGUAU CUC UAU = tyr CUC = Leu
70. We have two genes for each trait – this is our GENOTYPE One gene came from mom, one from dad If the genes are alike, the individual is homozygous (RR, rr) If the genes are different , they are heterozygous (Rr) Some genes are dominant and others are recessive We only show a recessive trait if we have no dominant gene RR and Rr would “look” dominant rr would look recessive This diagram shows the cross between 2 heterozygous purple flowers Cross is: Bb x Bb Notice that 75% are purple and 25% white Genetics
78. Can you identify the genotypes of individuals 4, 7, 12?4 = Ee (parent 2 had to give an e) 7 = Ee (child is ee, so they had to have one e) 12 = ee (affected with recessive condition)
113. PLANT ADAPTATIONS Flowers and Fruits Root, stem, Leaf Flowers have bright petals to attract pollinators Pollen (Sperm) can be transferred by animals When egg joins with pollen, a seed is formed in the ovary The ovary becomes the fruit Fruit surrounds and protects seed Fruit also helps get baby plants in seeds away from parent plant Roots are adapted to absorb water with root hairs Leaves are adapted for photosynthesis by being flat and green Stems move water with xylem
145. Food CHAINS Original source of energy for most chains is the sun 1st trophic level is producer 2nd trophic level is primary consumer 2rd trophic level is secondary consumer Decomposer not shown on chain, but they recycle nutrients Energy is “lost” as you mover “up” the food chain
