Plants are mainly multicellular organisms, predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, plants were treated as one of two kingdoms including all living things that were not animals, and all algae and fungi were treated as plants. However, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes. By one definition, plants form the clade Viridiplantae, a group that includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, mosses, and the green algae, but excludes the red and brown algae.
Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ability to produce normal amounts of chlorophyll or to photosynthesize, but still have flowers, fruits, and seeds. Plants are characterized by sexual reproduction and alternation of generations, although asexual reproduction is also common.

WHAT IS PLANT?

Plants are essential for any ecosystem. They provide all the energy for the ecosystem, because they can get energy directly from sunlight. They use a process called photosynthesis to use energy from the sun to grow and reproduce. They also must get nutrients from the soil. Those nutrients get into the soil when decomposers break down waste and dead materials. Plants require space to grow and reproduce. The size of your ecodome will influence how much space your plants have.

All other organisms in the food chain get energy from plants, either by directly eating them as herbivores do, or by eating plant eaters, like carnivores do. Omnivores can get energy either by eating plants directly or by eating herbivores. Likewise, decomposers get energy either from plants or from the animals that eat them. Since all the energy in your ecosystem comes from plants, you’d better have a lot of them.

There are several different kinds of plants, and not all animals can eat all kinds of plants.

GRESS  are only edible to herbivores. That is because the plants contain kinds of fiber that many omnivores cannot digest efficiently. Many herbivores have specially adapted stomachs that allow them to digest these plants.

Introduction to the Plantae

The green kingdom

The Plantae includes all land plants: mosses, ferns, conifers, flowering plants, and so on—an amazing range of diverse forms. With more than 250,000 species, they are second in size only to the arthropoda. Plants have been around for a very long time. The plants first appeared in the Ordovician, but did not begin to resemble modern plants until the Late Silurian. By the close of the Devonian, about 360 million years ago, there were a wide variety of shapes and sizes of plants around, including tiny creeping plants and tall forest trees. The most striking, and important, feature of plants is their green color, the result of a pigment called chlorophyll. Plants use chlorophyll to capture light energy, which fuels the manufacture of food—sugar, starch, and other carbohydrates. Without these food sources, most life on earth would be impossible. There would still be mushrooms and algae, but there would be no fruits, vegetables, grains, or any animals (which ultimately rely on plants for their food too!) Another important contribution of plants is their shaping of the environment. Think of a place without plants. The only such places on earth are the arctic wastelands, really arid deserts, and the deep ocean. Everywhere else, from the tundra to the rainforest to the desert, is populated by plants. In fact, when we think of a particular landscape, it is the plants which first come to mind. Try to picture a forest without trees, or a prairie without grasses. It is the plants which produce and maintain the terrestrial environment as we know it.
