This is mossy stuff on a rock in my yard which is an example
of a bryophyte(big idea 1 #13), or
a nonvascular plant. Becuase they are nonvascular, they cannot grow very tall
and must be in a moist enviroment. They contain neither plowers or seeds.
This is the inside of a rusty and gross mailbox on the side
of a hill, containing within it the web of an arachnid(big idea 1 #8). arachnids are deffined by the
reliable source of wikipedia as "joint-legged creatures with eight legs,
which in some circumstances are transformed for sensory functions."
Examples are spiders, scorpions, and ticks. Their boddies have two distinct
segments and they tend to be hetrotrophs or parasites. The most common phobia
is arachnophobia.
These seasonally-confused flowers exemplify transpiration(big idea 2 #36), which is the mass flow of
liquid from the roots of the tree to the leaves to replace water that was lost
through pores. This is a vital process that is powered by the cohesion of water
and will supply the plant with electrons for photosystem I and II.
This rose bush is clearly very thorny, an example of adaption of a plant( big idea 1 #3). I would guess that these plants were eaten by hetrotrophs and through mutation one grew primitive spikes or thorns that prevented herbivors from easily eating folliage. This would promote reproductive success and would eventually become common within the population.
