1. Most of the solid matter of plants is obtained from the atmosphere. Through a process called photosynthesis, plants use energy from sunlight to convert carbon dioxide in the atmosphere into simple sugars.
2. These sugars are used as building materials and constitute the main structural components of plants. Plants mainly rely on soil for support and access to water, as well as important basic nutrients such as nitrogen and phosphorus. For most plants to grow successfully, they also need oxygen in the atmosphere (for respiration) and around the roots. However, some special vascular plants such as mangroves can allow their roots to grow in an oxygen-deficient environment.
3. Plants have the ability of photosynthesis - that is to say, they can use water, inorganic salts and carbon dioxide for photosynthesis with the help of light energy and chlorophyll that animals do not have, release oxygen, and produce glucose - a substance rich in energy, for plant use.
4. Plant chlorophyll contains magnesium. Plant cells have distinct cell walls and nuclei, and their cell walls are composed of a glucose polymer, cellulose.
5. The ancestors of all plants were single-celled non-photosynthetic organisms that engulfed photosynthetic bacteria, forming a mutually beneficial relationship: photosynthetic bacteria lived within plant cells (the so-called endosymbiosis).
