this root has been broken in half, revealing the inner layers. An important layer is the phloem(big idea 2#30), which is the nutrient transport of the plant. It is the middle layer of a plant stalk, between the xylem and the layer of supporting fibers. It moves sugars produces by photosynthisis around the plant to power growth and development. Along with the Xylem, it is the main transport tissue of the plant and a major factor in growth and survival.
the splashes/ ripples resulting from a skipped stone demonstrate cohesion(big idea 2#10). this molecular phenomina is more responcible for life as we know it than any ther in my oppinion. It is what allows unicellular organisms to survive and what makes plants stand tall. This is when two moleculas are polar and form hydrogen bonds to eachother. essentially, the liquid sticks to itself and it takes some force to break this attraction, seen here by the rock bouncing due to surface tension.
(this photo took probably 10 minutes to get right)
These are both the leaves of a eucalyptus tree with a different phenotype(big idea 3 #17). a phenotype is the physical embodiment of dominant and recessive alleles and is what is displayed due to genotype. This can either be the trait of the dominant allele, the recessive allele, or a mix depending on codominance ect. These leaves are the same in function but different in shape due to the expression of different genotypes.
