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.
Diamond prices typically increase at a higher rate from one weight / price bracket to the next. For example, price per carat for diamonds in the size bracket 1.00â1.49 carats could be $8,000, while price per carat in the bracket 1.49â1.99 carats can jump to $11,000.In a graph below you can see how fast the price per carat jumps with diamond weight moving from one carat weight bracket to another.ecause of this fact, you may occasionally hear some jewelers referring to a 1-carat diamond a âfour grainer,â which means in the past 1 carat was equal to four grains of rice. The weight of smaller diamonds is often expressed as points, not carats. One carat is equal to 100 points.
