What are two challenges land plants experienced in their transition from an aquatic environment?

Dealing with dryness and lack of buoyancy.

What differences would you expect to see in a plant that is wind pollinated vs one that is pollinated by bees?

Bee-pollinated plants may have colorful flowers; wind-pollinated plants produce large quantities of small pollen.

How do plants transport water, minerals, and sugar through their tissues?

Xylem transports water and minerals; phloem transports sugar.

Locomotion and prey capture.

What is secondary radial symmetry?

Echinoderms have bilaterally symmetrical larvae and develop radial symmetry later in life.

How does counter-current flow facilitate diffusion of oxygen into fish gills?

It allows blood to continually encounter water with higher oxygen concentrations.

What is the difference between endothermy and homeothermy?

Endothermy is heat from internal sources; homeothermy is stable body temperature.
