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.
If her heart is set on a round 1 carat diamond, you can expect to pay between $3,500-$5,500. Conversely, princess diamonds tend to be less costly, as they retain more carat weight during the cutting process. The typical price range for a 1 carat princess cut would be between $3,000-$4,500 (a savings of 15-30%). While the princess cut is relatively new, it is often desired due to the unique cutting and polishing techniques that hide inclusions and show color more clearly.
