Examples of plant organisms are ferns, grass, flowers, trees and any other multicellular organisms that aren't animals. Plants are multicellular organisms that contain chloroplasts. The chloroplasts within plant cells contain chlorophyll, which is what plants use to create energy through photosynthesis. It also gives plants their green color.Continue Reading
There are more than 2 million known species of plants that contain chloroplasts. However, not all plants can produce energy through photosynthesis. The species that are unable to produce their own energy are parasitic and must take their nutrients from a host organism.
There are many different groups of plants, some which live on land and others in the water. Some of the major groups include gymnosperms, angiosperms, green algae, flowering plants and ferns, each consisting of numerous genera and species. Other groups of plants include mosses, liverworts and hornworts. Flowering plants are one of the largest groups of either plants or animals, with more than 250,000 known species, making it second only to the arthropod group.
Plants are thought to have evolved from algae more than 400 million years ago. Fossil records show the first vascular plants appeared approximately 370 million years ago, and flowering plants evolved around 130 million years ago.Learn more about Biology
Biological science, or biology, is the study of living organisms, such as plants, animals and other living organisms. The subject of biology is divided into many separate fields, such as behavior, human anatomy, botany, physiology, zoology, ecology and genetics.Full Answer >
Carl Linnaeus grouped organisms by the binominal system, a system he invented for separating animals and plants into a genus name and a species name. Linnaeus is called "the Father of Taxonomy" for his work in species classification.Full Answer >
Human beings require air because, like all other animals, they are aerobic organisms who require oxygen, which is a component of air. While oxygen is found in water, humans evolved to extract the oxygen from air, as birds, mammals and reptiles do, instead of from the water, as fish and some amphibians do. Additionally, air is necessary to keep the planet warm as it insulates the planet like a blanket.Full Answer >
Plants and animals are multi-cellular organisms composed of eukaryotic cells, while bacteria are single-cell prokaryotic organisms. Each eukaryotic cell of a plant or animal includes a central nucleus containing DNA and membrane-bound organelles, such as endoplasmic reticulum and mitochondria. A bacterial cell has no nucleus or membrane-bound organelles.Full Answer >
