__**How Scientists Classify Different Plants**__

How scientists classify different plants. Sometimes they may classify them according to their characteristics. Like the way they live, their habitat, what they may eat, their life cycle, and sometimes the way they look. Then they try to develop questions that may help them to classify. Now days to make it easier for scientists they use a classification system that was designed by Carolus Linnaeus in 1735. He was the first scientist to divide living thing in to groups called kingdoms. He only thought of five kingdoms in total. But the main two kingdoms are plants and animals. To help scientists classify thousands of species, they often use questions like I said before, here are the three important questions they use to help them classify thousands of different species:


 * Does this plant have roots, stems and leaves?


 * Does it produce cones or flowers?[[image:http://www.the-simple-homeschool.com/image-files/seedfruit.gif width="300" height="330" align="right"]]


 * Does it have a tube like structor to help it transport water?

These three questions will then help the scientist to organize the species into four main groups. The four groups are: mosses, liverworts, hornworts, ferns and their relatives conifers.

__**How Plants Reproduce**__

Plants are mostly divided into these three groups according to how they reproduce. Here are the three main groups they may most likely be divided by:


 * Plants that reproduce with seeds from flowers


 * Plants that reproduce with spores


 * Plants that reproduce with seeds from cones

How plants may reproduce is usually they may have a sort of seed inside them. Then the seeds may fall down to the ground. The weather may do the rest by giving it sunlight and rain. Then a new plant may grow. For example, lets observe and cherry tree. First a tree grows. Then beautiful flowers blossom. Later in a couple of months cherry’s replace the flowers. Then if the cherry’s are not picked to be eaten, they may rot and the seeds may fall. Then the weather will do the rest of the job by making it rain, giving it sunshine and before you know it, a new cherry tree will be growing!
