Published by Houghton Mifflin Harcourt Publishing Company. any member of the kingdom Plantae, comprising multicellular organisms that typically produce their own food from inorganic matter by the process of photosynthesis and that have more or less rigid cell walls containing cellulose, including vascular plants, mosses, liverworts, and hornworts: some classification schemes may include fungi, algae, bacteria, blue-green algae, and certain single-celled eukaryotes that have plantlike qualities, as rigid cell walls or photosynthesis. Today, most modern-day algae are classified as bacteria, not plants. Most plants grow in a fixed location and reproduce sexually, showing an alternation of generations between a diploid stage (with each cell having two sets of chromosomes) and haploid stage (with each cell having one set of chromosomes) in their life cycle. Plants, algae and cyanobacteria are the major groups of organisms that carry out photosynthesis, a process that uses the energy of sunlight to convert water and carbon dioxideinto sugars that can be used both as a source of chemical energy and of organic molecules that … a line of dialogue, or a character, action, etc., introducing an idea or theme that will be further developed at a later point in the play: Afterward we remembered the suicide plant in the second act.
