How could you resist drying conditions?
Adaptations to shallow water may have “set the stage” for the invasion of land…
The selective advantages of invading this new habitat…
What reproductive and other innovations allowed certain plant species to dominate the earth?
What problems did these innovations solve?
…waxy cuticle and protected gametes
Both female spores and developing embryos were protected from drying and UV radiation.
What are the functional names for male and female cones?
How does the evolution of wind-born male gametes (pollen) affect gene flow?
If pollination is more likely and more random by this method, why don’t we see many hybrids?
Identify the male and female gametophytes in the figure below.
What function is the seed coat providing as demonstrated in this photo?
