Homework Answers
During its initial development embryo floats over yolk but with time it sinks into yolk as it grows increases in mass and consumes yolk.
Yolk make up around 33-34% of a egg .Chicken egg yolk is a source of nutrients for growing embryo .It continue to be consumed by embryo .During its development fats are oxidized in yolk so overall weight of yolk will decrease with time . Metabolism will lead to further reduction in weight . But embryo continue to increase as proteins are being synthesised .

1) Compare and contrast embryo development in from fertilization to mature seed. 2) Fabian performed a mutant screen and found a plant the was extra droopy when compared to wildtype. Upon further analysis, he found that the plant’s stomata didn’t open very well. What kind of gene/protein might have been mutated in this plant? 3) How does plant biotechnology enable one to overcome genetic barriers between distant species (different genera or even families)
