Any two characteristics of pteridophyts are:
They are seedless, vascular plants that show true alternation of generations.
They reproduce by spores, which are developed in sporangia.
They must live near water because their skin needs to absorb water and oxygen otherwise their skin dries out and they can die

Chemiosmosis is the process that allows the diffusion of a
molecule or an atom through the membrane. Also, it is the movement of ions
across semipermeable membrane down their electrochemical gradients. In chloroplast,
chemiosmotic coupling is an important factor in ATP production through proton
gradient establishment.
I think it’s a forelimb of a whale
Something with higher electric potential than the ground or a defined null or neutral point. Electrons flow from the positive point in a circuit. See also negative, null, and potential.
