Embryophyta is a clade within the Phragmoplastophyta, a larger clade that also includes several green algae groups. Embryophytes are the plants growing on land which include hornworts, liverworts, gymnosperms, flowering plants etc while green algae mostly thrive in aquatic environment.
The conduction of water requires vascular tissue called xylem. In green algae, it is not necessary to have water conducting tissue as the entire body is in contact with water. However in embryophytes, having a vascular tissue is an adaptation that ensures to provide water to the higher parts of the plant which is not directly in contact with the soil.
Answer:Organ
Explanation:An organ may be defined as a group of tissues which perform similar functions. Organs can be found in both plants and animals,functionally related organs often cooperate to form systems. These organs are interdependent on each other to make up organ systems. Organ systems can be found in the different parts of the body. For instance,the esophagus,stomach and liver make up the digestive system and in the excretory system the skin and kidney are examples of the organs that can be found here. The main tissues of an organ tend to have the same embryological origin. This simply means that they arise from the same germ layer and by germ layer we mean the primary layer of cells that form during embryonic development. In plants however,the main organs are the roots,stem and leaves whose primary functions are to give nourishment to the plant. Reproductive organs of plants include the seed,flowers and spores which maintain the basic life processes of the plant.
<span>Sir Isaac Newton quantified the gravity between two objects when he formulated his three laws of motion. ... Yet Newton's laws assume that gravity is an innate force of an object that can act over a distance

In 1905, Albert Einstein determined that the laws of physics are the same for all non-accelerating observers, and that the speed of light in a vacuum was independent of the motion of all observers. This was the theory of special relativity. It introduced a new framework for all of physics and proposed new concepts of space and time.
Einstein then spent 10 years trying to include acceleration in the theory and published his theory of general relativity in 1915. In it, he determined that massive objects cause a distortion in space-time, which is felt as gravity.
