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.
Diamond Pricing: 1 carat diamonds are an affordable option for many. The price range for 1 carat diamonds is between $3,080 and $26,950 per carat. Round Brilliant Cut stones have a 6.5mm diameter. 1 carat diamonds are often sold because they make for great shoulder stones.
First of all, diamonds are all priced per carat. So, lets say a 0.50 carat diamond has a price of $1400 per carat. That diamondâs price for the stone would be $1400 * 0.50, or $700. Secondly, diamond prices per carat increase as you jump up to higher weight categories.ets say, for example, that you have a 1.55ct H color SI1 clarity diamond. The âRap Priceâ for that diamond would be $7,600 per carat. But finding the Rap Price for your diamond is only the beginning of pricing a diamond.
