While it may have many separate parts, the organism cannot survive without the parts, as the parts cannot survive without the organism. As plants die, the amount of oxygen available to other life-forms decreases. Various types of plant communities resemble or differ from each other in different ways. Explore all 4 major phyla of the plants here. Cyanobacteria, and bacteria in general, are prokaryotic life forms. The process of osmosis concerns the flow of a solvent, such as water, through a semipermeable membrane. There are close to 300,000 species of catalogued plants. All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. The essential mineral elements are: . Phototropism is a plant’s response to stimuli (turning toward the light). Fossil plant remains that clearly show features of true plants date back to 475 million years ago.
