Plants are extremely complex and adverse. They have thousands of species. In fact, they are probably somewhere around half million different species. And these are just the ones we know about. There are no doubt many more that haven't been fully discovered yet. It is estimated that 1 in 5, 30% of plant species are threatened with extinction. In order to continue studying these plant species, we need to organise them in different groups. This is known as plant classification. Plants all have some common parts that maintain a survival, but beyond that they can look very very different. These differences help partners classify and organise plants. Plants within a group are more closely related to other members of their own group than they are two members of another group. Just like we as humans are more closely related to the great apes than we are to other mammals. So how are plants classified? The plant kingdom can be split into plants with seeds and plants with art seeds. Not every plant grows from a seed, like ferns and masters for example. They grow from spores instead. Other plants use asexual reproduction and grow new plants from rhizomes or tubers. The evolution of a seed was a huge evolutionary step for plants. It meant they could grow anywhere on earth in any environment. There were no longer limited to extremely moist conditions. Seed plants can be split into flowering plants and non-flying plants. These have scientific names of germinous bones and angiosperms. As in a name non-flying plants do not produce flowers. They also reproduce by means of exposed seed or ovule. Rose sperm means naked seed. Like with conifers, the cone on a pine tree is a naked seed and they do not produce flowers. Gemini sperms are usually tall evergreen trees often with needle shaped leaves. They are usually found in dry places. Now for angiosperms, the largest and the most diverse group in the plant kingdom. Angiosperms consist of two major groups, monocotyledans and diacotyledans. These groups differ with respect to roots, stems, leaves, flowers, fruits and seeds. Some observable differences are that monocots have parallel veins and petals in groups of three. Whereas diocots have mid-like veins and petals in groups of four or five. There are other differences as well, but we don't need to worry too much about these at the stage. Grass and maize examples of monocots, whereas trees, sunflowers and roses are examples of diacots. So there we have some of the ways plants are classified. You need to remember that non-flying plants are called gemnospirms and have naked seeds. And then flowering plants are called angiosperms, which can be separated into monocots and diacrons.
