They are multicellular. They all have chlorophyll and make their own food by Photosynthesis (autotrophic).
Gymnosperms or Non-flowering plants The plants that do not have flowers, but usually bear spores are called Gymnosperms. Non flowering plants are usually simpler than flowering plants. But because they do not have flowers, they have to reproduce in other ways. Non flowering plants grow from spores and not seeds.

Algae, diverse group of simple, plantlike organisms. Like plants, most algae use the energy of sunlight to make their own food. However, algae lack the roots, leaves, and other structures typical of true plants.
Algae are the most important photosynthesizing organisms on Earth. They capture more of the sun’s energy and produce more oxygen than all plants combined. Algae form the foundation of most aquatic food webs, which support an abundance of animals.
Fungus, any member of a diverse group of organisms obtain food by absorbing nutrients from an external source. The fossil record suggests that fungi were present 550 million years ago and may have evolved even earlier.
Today thousands of different types of fungi grow on and absorb food from substances such as soil, wood, decaying organic matter, or living plants and other organisms. They range from tiny, single-celled organisms invisible to the naked eye to some of the largest living multicellular organisms.
Bryophytes or mosses Moss plants consist of small, slender stalks and leaves; vascular tissue is not present. They lack true roots, the functions of underground support and conduction being carried on by filamentous structures called rhizoids.

Pteridophytes or ferns Fern, common name for any of a division of cryptogamous (spore-producing) plants. The fern phylum contains about 150 genera; estimates of the number of species range from 6000 to 15,000. Ferns are found throughout the world. Most grow in damp, shady places, although certain species grow on dry ground, soil, or rocks. Some ferns, in fact, grow only in rocky places—in fissures and crevices of cliff faces and in boulders. Others grow as epiphytes, or air plants, on trees. Plant Kingdom Gymnosperms Angiosperms Algae Fungi Bryophytes Pteridophytes Monocotyledons Dicotyledons
Angiosperm (Latin angi-, “enclosed”; Greek sperma, “seed”), common name for the division or phylum comprising flowering plants, the dominant form of plant life. Members of the division are the source of most of the food on which humans and other mammals rely and of many raw materials and natural products. Included in the division are most shrubs and herbs, most familiar trees except pines and other conifers, and specialized plants such as succulents, parasites, and aquatic types. Although about 230,000 species are known, many remain obscure. Flowering plants occupy almost every ecological situation and dominate most natural landscapes.
