All organisms in the Kingdom Plantae are multicellular, which means that each organism is comprised of more than one cell. Being multicellular allows plants to grow large and complex, since the cells can differentiate and serve various different functions for the plant.Know More
In addition to multicellularity, all plants share several other characteristics. They are capable of making their own food through a process called photosynthesis, which involves absorbing light energy from the sun and converting it to chemical energy stored in carbohydrates. All plant cells have cell walls comprised of a carbohydrate material called cellulose, and they have the ability to grow larger through cell division. Plants lack motility. They reproduce both sexually and asexually.
Plants are divided into four main phyla based on shared characteristics.
The Phylum Bryophyta contains plants, such as mosses and liverworts, which lack vascular tissue that other plants use to transport water and nutrients. The Phylum Pteridophytae contains plants, such as horsetails and ferns, which have vascular tissue but do not reproduce with seeds. Most plants belong to either the Phylum Angiosperm or Phylum Gymnosperm. Phylum Angiosperm contains flowering plants, such as sunflowers and apple trees, which reproduce with developed seeds. Phylum Gymnosperm includes palm trees and other nonflowering plants that reproduce with undeveloped, primitive seeds.Learn more about Botany
DNA is often referred to as the blueprint for life because all living organisms have DNA, including plants. DNA stores the genetic information that links every organism to a common ancestry. Some plants, such as onions and tomatoes, have more DNA than humans.Full Answer >
The defining characteristic of multicellular organisms is the possession of more than one cell. In order for a multicellular organism to function, its constituent cells must be capable of identifying and attaching to one another.Full Answer >
A spirogyra is a multi-cellular organism that is also a plant-like protists. It is a filamentous type of green algae found in fresh bodies of water. Its name is derived from its chloroplast that is spiral-shaped.Full Answer >
Multicellular organisms are composed of more than one cell, while unicellular organisms are a single living cell. This difference determines the size and complexity of an organism, as well as the division of labor within it. Each kind of organism has its own set of survival benefits.Full Answer >
