Write two examples for each of the following.

Plants and animals are the two major classifications of living things. All species under these two kingdoms require proper functioning of their body processes to survive. Among the most important of the body processes is the transport system, which enables all other body systems to function smoothly and -- by supplying sufficient nutrients -- allows members of the species to go about their normal activities.

Railway Ecology pp Cite as. Biological invasions are a major component of global environmental change, threatening biodiversity and human well-being. These invasions have their origin in the human-mediated transportation of species beyond natural distribution ranges, a process that has increased by orders of magnitude in recent decades as a result of accelerating rates of international trade, travel, and transport. We focus specifically on the role of rail vehicles in dispersing stowaway species, i. We place these processes in the context of biological invasions as a global phenomenon and provide examples from the literature. We also list general management recommendations for biological invasions highlighting the particularities associated with their management in railway transport systems. These approaches are not mutually exclusive, and they range from an expectation that natural processes e.

In order to carry on photosynthesis, green plants need a supply of carbon dioxide and a means of disposing of oxygen. In order to carry on cellular respiration, plant cells need oxygen and a means of disposing of carbon dioxide just as animal cells do. Unlike animals, plants have no specialized organs for gas exchange with the few inevitable exceptions! The are several reasons they can get along without them:. Normally stomata open when the light strikes the leaf in the morning and close during the night.

Circulation of blood in animals requires energy supplied from respiration used in pumping of the heart and muscle contractions. Transporting tissue in plant is xylem and phloem. It involves movement of water, salts and organic molecules (manufactured food). This Consists of xylem vessels and tracheids.

16.2D: Gas Exchange in Plants

The body of an organism requires nutrients and oxygen to carry out various life processes. Waste products, produced due to the various functions inside the body also need to be transported and removed. Therefore, the term transport may be defined as a life process in which a material is absorbed in one part or organ of an organism and is carried to other parts in its body. In animal body, these functions are carried out by an internal transport system called as circulatory system. Circulatory System Circulatory system or blood circulatory system is the main transport system in human beings and animals.

Y ou have learnt earlier that all organisms need food, water and oxygen for survival. They need to transport all these to various parts of their body. Further, animals need to transport wastes to parts from where they can be removed.

Xylem is one of the two types of transport tissue in vascular plants , phloem being the other. The basic function of xylem is to transport water from roots to stems and leaves, but it also transports nutrients. The most distinctive xylem cells are the long tracheary elements that transport water.

Transport in biology means carrying substance absorbed or made in the body of an organism to all other parts of its body.
