Plants share four characteristics that are structural and functional. Structurally, plants are separated into shoots and roots and they have protective layers that prevents water loss. Functionally, they synthesize their own food and use alternating reproductive processes in each generation.Know More
The structural similarities of plants are the shoots, or the plant above ground, including the leaves, flowers and stems. The roots lie underground, anchor the plant and take in nutrients and water. Furthermore, cells jackets around the gametes retain moisture so they won't dry out and reproduction is more likely. Also, plant surfaces exposed to air have a waxy layer called the cuticle to prevent drying.
Functionally, most plants do not eat other organisms. They synthesize their food from light, water and carbon dioxide. In addition, plants alternate between haploid and diploid generations. Diploid generations have a set of chromosomes from both parent plants. Haploid is just one set of chromosomes.Learn more in Botany
Plants provide food to people and animals, regulate the water cycle, create oxygen and provide a habitat for other species. Without plants, life on Earth would not be sustainable for most species, including humans.Full Answer >
Plants are green because of a pigment called chlorophyll. Chlorophyll absorbs all colors of visible light except for green, which is reflected. Thus, the reflection of the green part of visible light is what causes plants to look green.Full Answer >
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 >
Like other organisms, plants have mitochondria in order to generate ATP, an energy molecule that powers cellular function. ATP is created in the mitochondria of both plants and animals in a process called respiration.Full Answer >
