Any help (no matter how little) would be greatly appreciated!!!

algae
mosses
ferns
liverworts
2. Which stage is the haploid (1N) stage for either mosses or ferns?
gametophyte stage
sporophyte stage
zygote stage
none of the above
3. One characteristic that chordates share ONLY with echinoderms is that they both
have a mantle.
have a hydrostatic skeleton.
are deuterosomes.
have a pseudocoel.
4. Lycophyta are also called club mosses. Do these plants have a vascular system?
Yes
No
