First, all plants undergo an alternation of generations, between a haploid gametophyte stage and a diploid sporophyte stage. In the most primitive plants, like mosses, the gametophyte is dominant (i.e. it's big and green). In higher plants like ferns and fern allies, the sporophyte stage is dominant.s we pass from mosses to ferns, we see a gradual transition from primitive to modern traits. There are two major trends you should focus on in today's lab. The first is a transition in life cycles, the second is a change in basic internal structure.

A Crown is worth 5 shillings, it's a step up from a Florin which was worth 2 Shillings. Britain went to metric money in 1971, you would see these guys circulating into the early 90s although the Churchill pieces were mainly sold as souveniers. Face value today is 25p (1 Shilling = 5p) or about 38c. Numismatic value? I think theyre worth a few dollars at best if still in the original snap case.
