What is the main difference between the life cycles of members of phylum bryophyta and phylum pteridophyta?

mode of reproduction

Explanation: Phylum pteridophyte are vascular plants this means they are plants that possess xylem and phloem tissues. Phylum pteridophyte reproduce and disperse by spores. The dominant phase in pteridophyte is sporophyte.

Phylum bryophyte lack true roots and they are non-vascular plants (no xylem and phloem tissues). They reproduce via gamates, the dominant reproductive phase in bryophyte is gametophyte.

passive transport is a movement of biochemicals and other atomic or molecular substances across cell membranes without need of energy input. unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy.

so, according to what that says, i believe it's hypertonic and hypotonic.

good luck!

i believe this is true, if you're asking for whether its true or false. : )
