Ferns. Ferns, horsetails, and their allies make up the second group of land plants, the pteridophytes. These plants all have vascular systems, made up of xylem (flow of water and nutrients from roots to leaves) and phloem (flow of sugars and other metabolic products from leaves to roots).e will not go into the details of this, other than to state the two generations are called the gametophyte (produces gametes) and the sporophyte (produces spores) generations. We need to mention these because the four plant groups each have unique alternation of generations.
What the difference between Intel Cores: Core i3, Core i5, Core i7 â the difference in a nutshell. If you want a plain and simple answer, then generally speaking, Core i7s are better than Core i5s, which are in turn better than Core i3s.
For the most part, you'll get faster CPU performance from the Core i5 parts over Core i3. Some Core i5 processors are dual-core and some are quad-core. Most of the time, a true quad-core CPU will perform better than a dual-core processor, especially on multimedia tasks like video transcoding or photo editing. All Core i3 processor are dual core. Occasionally, you'll find an older Ivy Bridge processor like the Intel Core i3-3130M in a system that's the same price as system with a newer Haswell CPU like the Intel Core i3-4012Y.
